TextSelection.WordRight 方法
将选定文本右移指定的字数。
命名空间： EnvDTE
程序集： EnvDTE（在 EnvDTE.dll 中）
语法
声明
Sub WordRight ( _
Extend As Boolean, _
Count As Integer _
)
void WordRight(
bool Extend,
int Count
)
void WordRight(
[InAttribute] bool Extend,
[InAttribute] int Count
)
abstract WordRight :
Extend:bool *
Count:int -> unit
function WordRight(
Extend : boolean,
Count : int
)
参数
- Extend
类型：System.Boolean
可选。确定所移动的文本是否折叠。默认值为 false。
- Count
类型：System.Int32
可选。表示右移的字数。默认值为 1。
备注
如果 Extend 为 true，则选定文本的活动端右移 Count 个字。 否则，选定文本折叠并定位在活动端右边 Count 个字处。 若在 Count 个字前到达了文档的结尾，则定位在文档结尾。
如果 Count 的值为负，则 WordRight 的执行类似于 WordLeft 方法。
文本文档的活动语言管理器定义了“字”的含义。
示例
Sub WordRightExample()
' 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
