發行項

從搜尋模式中移除一個字元，然後將選取範圍移回到上一個符合項目。

命名空間： EnvDTE80
組件： EnvDTE80 (在 EnvDTE80.dll 中)

語法

'宣告
Function DeleteCharAndBackup As vsIncrementalSearchResult

vsIncrementalSearchResult DeleteCharAndBackup()

vsIncrementalSearchResult DeleteCharAndBackup()

abstract DeleteCharAndBackup : unit -> vsIncrementalSearchResult

function DeleteCharAndBackup() : vsIncrementalSearchResult

傳回值

型別：EnvDTE80.vsIncrementalSearchResult
vsIncrementalSearchResult 列舉型別。

備註

DeleteCharAndBackup 可以很有效率地反轉上一次的搜尋動作。最後一個字元從模式比對中移除了，而選取範圍也移回到上一個符合項目 (不論搜尋方向為何)。

範例

Sub testIS2()
    ' Before running, open a document in Visual Studio.
    ' Set variables for text pane.
    Dim tp As EnvDTE80.TextPane2
    tp = CType(DTE.ActiveDocument.ActiveWindow.Object.ActivePane, _
    TextPane2)
    ' Start an incremental search backward from
    ' the current insertion point in the document.
    tp.IncrementalSearch.StartBackward()
    ' Add the character "a" to the search pattern.
    tp.IncrementalSearch.AppendCharAndSearch(Asc("a"))
    ' Display the parent name for IncrementalSearch object.
    MsgBox("IncrementalSearch parent: " & _
    tp.IncrementalSearch.DTE.FullName)
    MsgBox("Search pattern length: " & _
    tp.IncrementalSearch.Pattern.Length)
    ' Perform incremental search using the pattern ("a").
    tp.IncrementalSearch.SearchWithLastPattern()
    ' After the search, exit incremental search mode.
    MsgBox("DeleteCharAndBackup")
    tp.IncrementalSearch.DeleteCharAndBackup()
    MsgBox("SearchForward")
    tp.IncrementalSearch.SearchForward()
    MsgBox("SearchBackward")
    tp.IncrementalSearch.SearchBackward()
    MsgBox("Exit")
    tp.IncrementalSearch.Exit()
End Sub
