c# – 如何以编程方式检查项目中是否使用了变量？

Find对象允许您搜索和替换支持此类操作的环境中的文本,例如代码编辑器.

它主要用于宏观录制目的.编辑器的宏记录机制使用Find而不是TextSelection.FindPattern,以便您可以发现全局查找功能,并且因为它通常比将TextSelection对象用于诸如Find-in-files之类的操作更有用.

如果搜索操作是异步的,例如“全部查找”,则在操作完成时会发生FindDone事件.

Sub ActionExample()
   Dim objFind As Find = objTextDoc.DTE.Find

   ' Set the find options.
   objFind.Action = vsFindAction.vsFindActionFindAll
   objFind.Backwards = False
   objFind.FilesOfType = "*.vb"
   objFind.FindWhat = "<Variable>"
   objFind.KeepModifiedDocumentsOpen = False
   objFind.MatchCase = True
   objFind.MatchInHiddenText = True
   objFind.MatchWholeWord = True
   objFind.PatternSyntax = vsFindPatternSyntax.vsFindPatternSyntaxLiteral
   objFind.ResultsLocation = vsFindResultsLocation.vsFindResultsNone
   objFind.SearchPath = "c:&;Your>&;Project>&;Path>"
   objFind.SearchSubfolders = False
   objFind.Target = vsFindTarget.vsFindTargetCurrentDocument
   ' Perform the Find operation.
   objFind.Execute()
End Sub

                               Handles FindEvents.FindDone
   Select Case Result 
        case vsFindResultFound
             'Found!
        case else
             'Not Found
   Ens select
