TextSelection.MoveToPoint 方法

将活动点移到给定位置。

命名空间：  EnvDTE
程序集：  EnvDTE（在 EnvDTE.dll 中）

语法

声明
Sub MoveToPoint ( _
    Point As TextPoint, _
    Extend As Boolean _
)

void MoveToPoint(
    TextPoint Point,
    bool Extend
)

void MoveToPoint(
    [InAttribute] TextPoint^ Point, 
    [InAttribute] bool Extend
)

abstract MoveToPoint : 
        Point:TextPoint * 
        Extend:bool -> unit 

function MoveToPoint(
    Point : TextPoint, 
    Extend : boolean
)

参数

• Point
  类型：EnvDTE.TextPoint
  必选。将字符移动到的位置。

• Extend
  类型：System.Boolean
  可选。默认值为 false。确定是否扩展当前的选定范围。如果 Extend 为 true，则选定内容的活动端会移到该位置，而定位端保留在原地。否则，两端都将移动到指定位置。此参数仅适用于 TextSelection 对象。

示例

Sub MoveToPointExample()
    ' Before running this example, open a text document.
    Dim objSel As TextSelection = DTE.ActiveDocument.Selection
    If objSel.IsEmpty Then
        ' If there is no text selected, swap the words before and after 
        ' the insertion point. We begin by selecting the word before 
        ' the insertion point.
        objSel.WordLeft(True)
        If Not objSel.IsEmpty Then
            ' We can continue only if the selection was not already at 
            ' the beginning of the document.
            Dim strBefore As String = objSel.Text

            ' The text is saved in strBefore; now delete it and move 
            ' past the following word.
            objSel.Delete()
            objSel.WordRight(True)
            If objSel.Text.StartsWith(" ") Or objSel.Text.StartsWith(Microsoft.VisualBasic.ControlChars.Tab) Then
                ' The previous call to WordRight may have skipped some 
                ' white space instead of an actual word. In that case, 
                ' we should call it again.
                objSel.WordRight(True)
            End If

            ' Insert the new text at the end of the selection.
            objSel.Insert(strBefore, vsInsertFlags.vsInsertFlagsInsertAtEnd)
        End If
    Else
        ' If some text is selected, replace the following word with the 
        ' selected text.
        Dim strSelected As String = objSel.Text

        objSel.MoveToPoint(objSel.BottomPoint)
        objSel.WordRight(True)
        If objSel.Text.StartsWith(" ") Or objSel.Text.StartsWith(Microsoft.VisualBasic.ControlChars.Tab) Then
            ' The previous call to WordRight may have skipped some 
            ' white space instead of an actual word. In that case, we 
            ' should call it again.
            objSel.WordRight(True)
        End If

        ' Insert the text, overwriting the existing text and leaving 
        ' the selection containing the inserted text.
        objSel.Insert(strSelected, vsInsertFlags.vsInsertFlagsContainNewText)
    End If
End Sub
