逐步解說: 顯示陳述式完成

發行項
03/24/2017

如需 Visual Studio 2017 的最新文件請參閱 Visual Studio 2017 文件。

您可以定義您要提供完成的識別項，然後觸發完成的工作階段，以實作語言為基礎的陳述式完成。您可以語言服務內容中定義陳述式完成、定義您自己的檔案名稱副檔名和內容類型，然後顯示完成只是該型別，或者完成現有的內容類型的觸發程序 — 例如，「純文字」。本逐步解說示範如何觸發陳述式完成「純文字」內容類型，也就是文字檔案的內容類型。「文字」內容類型是所有其他內容類型，包括程式碼和 XML 檔案的上階。

陳述式完成通常會觸發輸入特定的字元 — 例如，藉由輸入的識別碼，例如「使用」的開頭。它通常被按下空格鍵、 Tab 或 Enter 鍵，確認選取項目。您可以實作 IntelliSense 功能所觸發的輸入字元的按鍵輸入使用的命令處理常式 ( IOleCommandTarget介面) 和處理常式提供者實作IVsTextViewCreationListener介面。若要建立完成來源時，這是參與完成的識別項的清單，實作ICompletionSource介面和完成來源提供者 ( ICompletionSourceProvider介面)。提供者是 Managed Extensibility Framework (MEF) 元件組件。他們要負責匯出的來源和控制器類別和匯入服務和代理程式 — 例如， ITextStructureNavigatorSelectorService，可讓文字緩衝區中，瀏覽和ICompletionBroker，而觸發完成的工作階段。

本逐步解說示範如何實作硬式編碼的組的識別項的陳述式完成。在完整的實作中，語言服務和語言文件有責任提供該內容。

必要條件

啟動 Visual Studio 2015 中，您未安裝 Visual Studio SDK 從「下載中心」。它是 Visual Studio 安裝程式的選用功能。您也可以在稍後安裝 VS SDK。如需詳細資訊，請參閱安裝 Visual Studio SDK。

建立 MEF 專案

建立 C# VSIX 專案。 (在新的專案對話方塊中，選取Visual C# / 擴充性，然後VSIX 專案。)將方案命名為CompletionTest。
將編輯器分類項目範本加入至專案。如需詳細資訊，請參閱編輯器項目範本以建立副檔名為。
刪除現有類別檔案。
下列參考加入至專案，並確定CopyLocal設為false:

Microsoft.VisualStudio.Editor

Microsoft.VisualStudio.Language.Intellisense

Microsoft.VisualStudio.OLE.Interop

Microsoft.VisualStudio.Shell.14.0

Microsoft.VisualStudio.Shell.Immutable.10.0

Microsoft.VisualStudio.TextManager.Interop

實作完成來源

完成來源負責收集組的識別項，並將內容加入至完成視窗中，當使用者輸入完成觸發程序，例如識別項的第一個字母。在此範例中，識別項和其描述是硬式編碼AugmentCompletionSession方法。在大部分的實際用途，您會使用您的語言剖析器取得的權杖來擴展完成清單。

若要實作完成來源

將類別檔案，並將它TestCompletionSource。

新增這些匯入︰

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel.Composition;
using Microsoft.VisualStudio.Language.Intellisense;
using Microsoft.VisualStudio.Text;
using Microsoft.VisualStudio.Text.Operations;
using Microsoft.VisualStudio.Utilities;

Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Text
Imports System.ComponentModel.Composition
Imports Microsoft.VisualStudio.Language.Intellisense
Imports Microsoft.VisualStudio.Text
Imports Microsoft.VisualStudio.Text.Operations
Imports Microsoft.VisualStudio.Utilities

修改的類別宣告TestCompletionSource，使其實作ICompletionSource:

internal class TestCompletionSource : ICompletionSource

Friend Class TestCompletionSource
    Implements ICompletionSource

加入私用欄位的來源提供者、文字緩衝區，以及一份完成物件（對應至要參與完成的工作階段識別項）︰

    private TestCompletionSourceProvider m_sourceProvider;
    private ITextBuffer m_textBuffer;
    private List<Completion> m_compList;

    Private m_sourceProvider As TestCompletionSourceProvider
    Private m_textBuffer As ITextBuffer
    Private m_compList As List(Of Completion)

新增設定的來源提供者和緩衝區的建構函式。 TestCompletionSourceProvider類別定義於稍後的步驟︰

    public TestCompletionSource(TestCompletionSourceProvider sourceProvider, ITextBuffer textBuffer)
    {
        m_sourceProvider = sourceProvider;
        m_textBuffer = textBuffer;
    }

    Public Sub New(ByVal sourceProvider As TestCompletionSourceProvider, ByVal textBuffer As ITextBuffer)
        m_sourceProvider = sourceProvider
        m_textBuffer = textBuffer
    End Sub

實作AugmentCompletionSession您想要提供的內容中加入一個完成集合，包含所完成的方法。每個完成集包含一組完成完成項數目，而對應的索引標籤的 [完成] 視窗。 (在 Visual Basic 專案完成視窗索引標籤會命名為常見和所有。)FindTokenSpanAtPosition 方法被定義在下一個步驟。

    void ICompletionSource.AugmentCompletionSession(ICompletionSession session, IList<CompletionSet> completionSets)
    {
        List<string> strList = new List<string>();
        strList.Add("addition");
        strList.Add("adaptation");
        strList.Add("subtraction");
        strList.Add("summation");
        m_compList = new List<Completion>();
        foreach (string str in strList)
            m_compList.Add(new Completion(str, str, str, null, null));

        completionSets.Add(new CompletionSet(
            "Tokens",    //the non-localized title of the tab
            "Tokens",    //the display title of the tab
            FindTokenSpanAtPosition(session.GetTriggerPoint(m_textBuffer),
                session),
            m_compList,
            null));
    }

    Private Sub AugmentCompletionSession(ByVal session As ICompletionSession, ByVal completionSets As IList(Of CompletionSet)) Implements ICompletionSource.AugmentCompletionSession
        Dim strList As New List(Of String)()
        strList.Add("addition")
        strList.Add("adaptation")
        strList.Add("subtraction")
        strList.Add("summation")

        m_compList = New List(Of Completion)()
        For Each str As String In strList
            m_compList.Add(New Completion(str, str, str, Nothing, Nothing))
        Next str

        completionSets.Add(New CompletionSet(
            "Tokens",
            "Tokens",
            FindTokenSpanAtPosition(session.GetTriggerPoint(m_textBuffer),
                session),
            m_compList,
            Nothing))
    End Sub

若要尋找目前的文字從游標的位置使用下列方法︰

    private ITrackingSpan FindTokenSpanAtPosition(ITrackingPoint point, ICompletionSession session)
    {
        SnapshotPoint currentPoint = (session.TextView.Caret.Position.BufferPosition) - 1;
        ITextStructureNavigator navigator = m_sourceProvider.NavigatorService.GetTextStructureNavigator(m_textBuffer);
        TextExtent extent = navigator.GetExtentOfWord(currentPoint);
        return currentPoint.Snapshot.CreateTrackingSpan(extent.Span, SpanTrackingMode.EdgeInclusive);
    }

    Private Function FindTokenSpanAtPosition(ByVal point As ITrackingPoint, ByVal session As ICompletionSession) As ITrackingSpan
        Dim currentPoint As SnapshotPoint = (session.TextView.Caret.Position.BufferPosition) - 1
        Dim navigator As ITextStructureNavigator = m_sourceProvider.NavigatorService.GetTextStructureNavigator(m_textBuffer)
        Dim extent As TextExtent = navigator.GetExtentOfWord(currentPoint)
        Return currentPoint.Snapshot.CreateTrackingSpan(extent.Span, SpanTrackingMode.EdgeInclusive)
    End Function

實作Dispose()方法︰

    private bool m_isDisposed;
    public void Dispose()
    {
        if (!m_isDisposed)
        {
            GC.SuppressFinalize(this);
            m_isDisposed = true;
        }
    }

    Private m_isDisposed As Boolean
    Public Sub Dispose() Implements IDisposable.Dispose
        If Not m_isDisposed Then
            GC.SuppressFinalize(Me)
            m_isDisposed = True
        End If
    End Sub

實作完成來源提供者

完成來源提供者已具現化完成來源 MEF 元件組件。

若要實作完成來源提供者

新增名為TestCompletionSourceProvider實作ICompletionSourceProvider。匯出與這個類別ContentTypeAttribute 「純文字」和NameAttribute的「測試完成」。

[Export(typeof(ICompletionSourceProvider))]
[ContentType("plaintext")]
[Name("token completion")]
internal class TestCompletionSourceProvider : ICompletionSourceProvider

<Export(GetType(ICompletionSourceProvider)), ContentType("plaintext"), Name("token completion")>
Friend Class TestCompletionSourceProvider
    Implements ICompletionSourceProvider

匯入ITextStructureNavigatorSelectorService，用來尋找目前的文字完成來源中。

    [Import]
    internal ITextStructureNavigatorSelectorService NavigatorService { get; set; }

    <Import()>
    Friend Property NavigatorService() As ITextStructureNavigatorSelectorService

實作TryCreateCompletionSource方法具現化完成來源。

    public ICompletionSource TryCreateCompletionSource(ITextBuffer textBuffer)
    {
        return new TestCompletionSource(this, textBuffer);
    }

    Public Function TryCreateCompletionSource(ByVal textBuffer As ITextBuffer) As ICompletionSource Implements ICompletionSourceProvider.TryCreateCompletionSource
        Return New TestCompletionSource(Me, textBuffer)
    End Function

實作完成命令處理常式提供者

完成命令處理常式提供者衍生自IVsTextViewCreationListener，其文字檢視建立事件接聽，並將從檢視轉換IVsTextView— 可讓 Visual Studio shell 的命令鏈結的命令加入 — 至ITextView。因為這個類別是 MEF 匯出，您也可以使用它來匯入命令處理常式本身所需的服務。

若要實作完成命令處理常式提供者

新增名為TestCompletionCommandHandler。

加入下列 using 陳述式︰

using System;
using System.ComponentModel.Composition;
using System.Runtime.InteropServices;
using Microsoft.VisualStudio;
using Microsoft.VisualStudio.Editor;
using Microsoft.VisualStudio.Language.Intellisense;
using Microsoft.VisualStudio.OLE.Interop;
using Microsoft.VisualStudio.Shell;
using Microsoft.VisualStudio.Text;
using Microsoft.VisualStudio.Text.Editor;
using Microsoft.VisualStudio.TextManager.Interop;
using Microsoft.VisualStudio.Utilities;

Imports System

Imports Microsoft.VisualStudio.OLE.Interop
Imports Microsoft.VisualStudio.Shell
Imports Microsoft.VisualStudio.Text
Imports Microsoft.VisualStudio.Text.Editor
Imports Microsoft.VisualStudio.TextManager.Interop
Imports Microsoft.VisualStudio.Utilities

新增名為TestCompletionHandlerProvider實作IVsTextViewCreationListener。匯出與這個類別NameAttribute 「語彙基元的完成處理常式」的ContentTypeAttribute 「純文字」和TextViewRoleAttribute的編輯。

[Export(typeof(IVsTextViewCreationListener))]
[Name("token completion handler")]
[ContentType("plaintext")]
[TextViewRole(PredefinedTextViewRoles.Editable)]
internal class TestCompletionHandlerProvider : IVsTextViewCreationListener

<Export(GetType(IVsTextViewCreationListener))>
<Name("token completion handler")>
<ContentType("plaintext")> <TextViewRole(PredefinedTextViewRoles.Editable)>
Friend Class TestCompletionHandlerProvider
    Implements IVsTextViewCreationListener

匯入IVsEditorAdaptersFactoryService，可讓從轉換IVsTextView至ITextView、 ICompletionBroker，和SVsServiceProvider ，可讓您存取標準的 Visual Studio 服務。

    [Import]
    internal IVsEditorAdaptersFactoryService AdapterService = null;
    [Import]
    internal ICompletionBroker CompletionBroker { get; set; }
    [Import]
    internal SVsServiceProvider ServiceProvider { get; set; }

    <Import()>
    Friend AdapterService As IVsEditorAdaptersFactoryService = Nothing
    <Import()>
    Friend Property CompletionBroker() As ICompletionBroker
    <Import()>
    Friend Property ServiceProvider() As SVsServiceProvider

實作VsTextViewCreated方法具現化的命令處理常式。

    public void VsTextViewCreated(IVsTextView textViewAdapter)
    {
        ITextView textView = AdapterService.GetWpfTextView(textViewAdapter);
        if (textView == null)
            return;

        Func<TestCompletionCommandHandler> createCommandHandler = delegate() { return new TestCompletionCommandHandler(textViewAdapter, textView, this); };
        textView.Properties.GetOrCreateSingletonProperty(createCommandHandler);
    }

    Public Sub VsTextViewCreated(ByVal textViewAdapter As IVsTextView) Implements IVsTextViewCreationListener.VsTextViewCreated
        Dim textView As ITextView = AdapterService.GetWpfTextView(textViewAdapter)
        If textView Is Nothing Then
            Return
        End If

        Dim createCommandHandler As Func(Of TestCompletionCommandHandler) = Function() New TestCompletionCommandHandler(textViewAdapter, textView, Me)
        textView.Properties.GetOrCreateSingletonProperty(createCommandHandler)
    End Sub

實作完成命令處理常式

因為按鍵動作所觸發陳述式完成時，您必須實作IOleCommandTarget介面來接收及處理觸發程序、認可和關閉完成的工作階段的按鍵。

若要實作完成命令處理常式

新增名為TestCompletionCommandHandler實作IOleCommandTarget:

internal class TestCompletionCommandHandler : IOleCommandTarget

Friend Class TestCompletionCommandHandler
    Implements IOleCommandTarget

加入私用欄位（要您傳遞的命令）的下一個命令處理常式、文字檢視、命令處理常式提供者（這可讓您存取各種服務），並完成工作階段︰

    private IOleCommandTarget m_nextCommandHandler;
    private ITextView m_textView;
    private TestCompletionHandlerProvider m_provider;
    private ICompletionSession m_session;

    Private m_nextCommandHandler As IOleCommandTarget
    Private m_textView As ITextView
    Private m_provider As TestCompletionHandlerProvider
    Private m_session As ICompletionSession

新增的建構函式，設定文字檢視和 [提供者] 欄位中，並將命令加到命令鏈結︰

    internal TestCompletionCommandHandler(IVsTextView textViewAdapter, ITextView textView, TestCompletionHandlerProvider provider)
    {
        this.m_textView = textView;
        this.m_provider = provider;

        //add the command to the command chain
        textViewAdapter.AddCommandFilter(this, out m_nextCommandHandler);
    }

    Friend Sub New(ByVal textViewAdapter As IVsTextView, ByVal textView As ITextView, ByVal provider As TestCompletionHandlerProvider)
        Me.m_textView = textView
        Me.m_provider = provider

        'add the command to the command chain
        textViewAdapter.AddCommandFilter(Me, m_nextCommandHandler)
    End Sub

實作QueryStatus方法傳遞沿著命令︰

    public int QueryStatus(ref Guid pguidCmdGroup, uint cCmds, OLECMD[] prgCmds, IntPtr pCmdText)
    {
        return m_nextCommandHandler.QueryStatus(ref pguidCmdGroup, cCmds, prgCmds, pCmdText);
    }

    Public Function QueryStatus(ByRef pguidCmdGroup As Guid, ByVal cCmds As UInteger, ByVal prgCmds() As OLECMD, ByVal pCmdText As IntPtr) As Integer Implements IOleCommandTarget.QueryStatus
        Return m_nextCommandHandler.QueryStatus(pguidCmdGroup, cCmds, prgCmds, pCmdText)
    End Function

實作Exec方法。當這個方法會接收按鍵動作時，它必須執行這些動作的其中一個動作︰

允許寫入緩衝區，並接著觸發程序或篩選完成的字元。（列印的字元進行。）
認可完成，但不是允許寫入緩衝區的字元。（空格、定位及 Enter 時執行此動作會顯示完成的工作階段。）
允許命令傳遞至下一個處理常式。（所有其他命令）。

因為這個方法可能會顯示 UI，所以呼叫IsInAutomationFunction確保不會呼叫內容中的自動化︰

    public int Exec(ref Guid pguidCmdGroup, uint nCmdID, uint nCmdexecopt, IntPtr pvaIn, IntPtr pvaOut)
    {
        if (VsShellUtilities.IsInAutomationFunction(m_provider.ServiceProvider))
        {
            return m_nextCommandHandler.Exec(ref pguidCmdGroup, nCmdID, nCmdexecopt, pvaIn, pvaOut);
        }
        //make a copy of this so we can look at it after forwarding some commands
        uint commandID = nCmdID;
        char typedChar = char.MinValue;
        //make sure the input is a char before getting it
        if (pguidCmdGroup == VSConstants.VSStd2K && nCmdID == (uint)VSConstants.VSStd2KCmdID.TYPECHAR)
        {
            typedChar = (char)(ushort)Marshal.GetObjectForNativeVariant(pvaIn);
        }

        //check for a commit character
        if (nCmdID == (uint)VSConstants.VSStd2KCmdID.RETURN
            || nCmdID == (uint)VSConstants.VSStd2KCmdID.TAB
            || (char.IsWhiteSpace(typedChar) || char.IsPunctuation(typedChar)))
        {
            //check for a a selection
            if (m_session != null && !m_session.IsDismissed)
            {
                //if the selection is fully selected, commit the current session
                if (m_session.SelectedCompletionSet.SelectionStatus.IsSelected)
                {
                    m_session.Commit();
                    //also, don't add the character to the buffer
                    return VSConstants.S_OK;
                }
                else
                {
                    //if there is no selection, dismiss the session
                    m_session.Dismiss();
                }
            }
        }

        //pass along the command so the char is added to the buffer
        int retVal = m_nextCommandHandler.Exec(ref pguidCmdGroup, nCmdID, nCmdexecopt, pvaIn, pvaOut);
        bool handled = false;
        if (!typedChar.Equals(char.MinValue) && char.IsLetterOrDigit(typedChar))
        {
            if (m_session == null || m_session.IsDismissed) // If there is no active session, bring up completion
            {
                this.TriggerCompletion();
                m_session.Filter();
            }
            else    //the completion session is already active, so just filter

        }
        if (handled) return VSConstants.S_OK;
        return retVal;
    }

此程式碼是觸發程序完成的工作階段的私用方法︰

    private bool TriggerCompletion()
    {
        //the caret must be in a non-projection location 
        SnapshotPoint? caretPoint =
        m_textView.Caret.Position.Point.GetPoint(
        textBuffer => (!textBuffer.ContentType.IsOfType("projection")), PositionAffinity.Predecessor);
        if (!caretPoint.HasValue)
        {
            return false;
        }

        m_session = m_provider.CompletionBroker.CreateCompletionSession
     (m_textView,
            caretPoint.Value.Snapshot.CreateTrackingPoint(caretPoint.Value.Position, PointTrackingMode.Positive),
            true);

        //subscribe to the Dismissed event on the session 
        m_session.Dismissed += this.OnSessionDismissed;
        m_session.Start();

        return true;
    }

    Private Function TriggerCompletion() As Boolean
        'the caret must be in a non-projection location 
        Dim caretPoint As SnapshotPoint? = m_textView.Caret.Position.Point.GetPoint(Function(textBuffer) ((Not textBuffer.ContentType.IsOfType("projection"))), PositionAffinity.Predecessor)
        If Not caretPoint.HasValue Then
            Return False
        End If

        m_session = m_provider.CompletionBroker.CreateCompletionSession(m_textView, caretPoint.Value.Snapshot.CreateTrackingPoint(caretPoint.Value.Position, PointTrackingMode.Positive), True)

        'subscribe to the Dismissed event on the session 
        AddHandler m_session.Dismissed, AddressOf OnSessionDismissed
        m_session.Start()

        Return True
    End Function

下一個範例會從取消訂閱的私用方法Dismissed事件︰

    private void OnSessionDismissed(object sender, EventArgs e)
    {
        m_session.Dismissed -= this.OnSessionDismissed;
        m_session = null;
    }

    Private Sub OnSessionDismissed(ByVal sender As Object, ByVal e As EventArgs)
        RemoveHandler m_session.Dismissed, AddressOf OnSessionDismissed
        m_session = Nothing
