TextSelection.ReplacePattern Method

  • Artykuł

Replaces matching text throughout an entire text document.

Namespace:  EnvDTE
Assembly:  EnvDTE (in EnvDTE.dll)

Syntax

'Declaration
Function ReplacePattern ( _
    Pattern As String, _
    Replace As String, _
    vsFindOptionsValue As Integer, _
    <OutAttribute> ByRef Tags As TextRanges _
) As Boolean

bool ReplacePattern(
    string Pattern,
    string Replace,
    int vsFindOptionsValue,
    out TextRanges Tags
)

bool ReplacePattern(
    [InAttribute] String^ Pattern, 
    [InAttribute] String^ Replace, 
    [InAttribute] int vsFindOptionsValue, 
    [InAttribute] [OutAttribute] TextRanges^% Tags
)

abstract ReplacePattern : 
        Pattern:string * 
        Replace:string * 
        vsFindOptionsValue:int * 
        Tags:TextRanges byref -> bool 

function ReplacePattern(
    Pattern : String, 
    Replace : String, 
    vsFindOptionsValue : int, 
    Tags : TextRanges
) : boolean

Parameters

  • Replace
    Type: System.String
    Required. The text to replace each occurrence of Pattern.
  • vsFindOptionsValue
    Type: System.Int32
    Optional. A vsFindOptions constant indicating the behavior of ReplacePattern, such as how to search, where to begin the search, whether to search forward or backward, and the case sensitivity.
  • Tags
    Type: EnvDTE.TextRanges%
    Optional. A TextRanges collection. If the matched text pattern is a regular expression and contains tagged subexpressions, then Tags contains a collection of EditPoint objects, one for each tagged subexpression.

Return Value

Type: System.Boolean
A Boolean value.

Remarks

ReplacePattern for the TextDocument object replaces text like ReplacePattern for the TextSelection object, but it operates on the whole text document rather than just the selected text.

The ReplacePattern method for Visual Studio is incompatible with earlier versions of the ReplacePattern method, because regular expressions now have a different syntax.

Examples

Sub ReplacePatternExample(dte As DTE)

    ' Create a new text file and insert 10 lines of text.
    dte.ItemOperations.NewFile()
    Dim txtSel As TextSelection = _
        CType(dte.ActiveDocument.Selection, TextSelection)
    Dim txtDoc As TextDocument = _
        CType(dte.ActiveDocument.Object(), TextDocument)
    Dim editPnt As EditPoint = txtDoc.StartPoint.CreateEditPoint()
    Dim i As Integer
    For i = 1 To 10
        editPnt.Insert("This is a test." & vbCrLf)
    Next i

    If MsgBox("Replace 'test' with 'done deal'?", vbYesNo) = _
        MsgBoxResult.Yes Then
        txtSel.SelectAll()
        txtSel.ReplacePattern("test", "done deal")
    End If

End Sub

public void ReplacePatternExample(DTE dte)
{
    // Create a new text file and insert 10 lines of text.
    dte.ItemOperations.NewFile(@"General\Text File", "", 
        Constants.vsViewKindPrimary);
    TextSelection txtSel = (TextSelection)dte.ActiveDocument.Selection;
    TextDocument txtDoc = (TextDocument)dte.ActiveDocument.Object("");
    EditPoint editPnt = txtDoc.StartPoint.CreateEditPoint();
    for (int i = 1; i <= 10; i++)
    {
        editPnt.Insert("This is a test." + Environment.NewLine);
    }

    if (MessageBox.Show("Replace 'test' with 'done deal'?", "", 
        MessageBoxButtons.YesNo) == DialogResult.Yes)
    {
        TextRanges dummy = null;
        txtSel.SelectAll();
        txtSel.ReplacePattern("test", "done deal", 
            (int)vsFindOptions.vsFindOptionsNone, ref dummy);
    }
}
