vb.net從複製中排除特定的文件名？

Question

如何在複製過程中排除正在複製的特定文件。我想從被複制例如name.xml的，adress.xml和data.xml中

這裏排除是從MSDN代碼我使用：

Dim BackupDir As String = Application.StartupPath & "\backup" 
    Dim sourceDir As String = Application.StartupPath 

    If Not Directory.Exists(BackupDir) Then 
     IO.Directory.CreateDirectory(BackupDir) 
    End If 

    Try 
     Dim xmlList As String() = Directory.GetFiles(sourceDir, "*.xml") 

     For Each f As String In xmlList 
      'Remove path from the file name. 
      Dim fName As String = f.Substring(sourceDir.Length + 1) 
      File.Copy(Path.Combine(sourceDir, fName), Path.Combine(BackupDir, fName), True) 
     Next 
    Catch copyError As IOException 
     Console.WriteLine(copyError.Message) 
    End Try

準備列表（串）與名您不想複製的文件，然後使用Path.GetFileName從Directory.GetFiles（）返回的完整文件名中提取文件名。 如果該文件包含在excludedFiles

Dim excludeFiles = new List(Of String)() 
    excludedFiles.Add("file1.xml") 
    excludedFiles.Add("file2.xml") 
    excludedFiles.Add("file3.xml") 


    For Each f As String In xmlList 
     'Remove path from the file name. 
     Dim fName As String = Path.GetFileName(f) 
      if excludedFiles.IndexOf("file3.xml", _ 
       StringComparison.CurrentCultureIgnoreCase) <> -1 Then 
      File.Copy(f, Path.Combine(BackupDir, fName), True) 
     End If 
    Next
