Syntax

'宣言
Public Sub New ( _
    languageService As Object, _
    languageName As String, _
    languageResourceId As Integer, _
    languageIdentifier As String, _
    pathToSnippetIndexFile As String _

public ProvideLanguageCodeExpansionAttribute(
    Object languageService,
    string languageName,
    int languageResourceId,
    string languageIdentifier,
    string pathToSnippetIndexFile
)

Parameters

• languageService
  Type: System.Object
  [in] This is either a string containing a GUID or a type representing the class that implements the language service. The language service GUID is derived from this string or type.

• languageName
  Type: System.String
  [in] The name of the language. This name is used in the registry for registry key and entry names.

• languageResourceId
  Type: System.Int32
  [in] The resource ID for the localized version of the language name. This is used to present the language name in dialog boxes and other user interface elements.

• languageIdentifier
  Type: System.String
  [in] A string containing an identifier specific to the language that is used to mark and identify code snippets.

• pathToSnippetIndexFile
  Type: System.String
  [in] A string containing the path to the code snippets index file for the language.

Remarks

The following registry layout shows where each of the required parameters is used.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\[X.Y]\Languages\
  Language Services\
    CodeExpansions\
      [languageName]\
        (Default) = reg_sz: [languageService]
         DisplayName  = reg_sz: [languageResourceId]
         IndexPath    = reg_sz: [pathToSnippetIndexFile]
         LangStringID = reg_sz: [languageIdentifier]
         Package      = reg_sz: [Package GUID]

The [Package GUID] value is automatically obtained from the class that implements the IVsPackage interface in the assembly.

In addition to the required parameters listed in the Parameters section, the constructor also accepts optional named parameters after the required parameters. This is a special form supported only in user-defined attributes. These named parameters correspond to the public properties on this class that have both get and set operators.

Examples

using Microsoft.VisualStudio.Shell;

namespace MyLanguagePackage
{
    internal class MyConstants
    {
        public const string languageName           = "MyLanguage";
        public const int    languageNameResourceID = 106;
        public const string languageIdentifier     = "mylanguage";
        public const string snippetsIndexFilePath   = @"%InstallRoot%\MyLanguage\SnippetsIndex.xml";
    }

    [ProvideCodeExpansion(typeof(MyLanguageService),            // Required
                            MyConstants.languageName,           // Required

                            MyConstants.snippetsIndexFilePath,  // Required
        // Optional code expansion properties
        SearchPaths = @"%InstallRoot%\MyLanguage\Snippets\%LCID%\Snippets;" +
                      @"\%MyDocs%\Code Snippets\MyLanguage\My Code Snippets";
