C#不直接提供重命名功能.但是您可以使用这两种方法中的任何一种.

1)
File.Copy(OldFileName，NewFileName);
File.Delete(OldFileName);
2)
File.Move(OldFileName，NewFileName);

C# doesn''t provide rename facility directly. But you can use either of these two methods.

1)
File.Copy(OldFileName, NewFileName);
File.Delete(OldFileName);
2)
File.Move(OldFileName,NewFileName);

System.IO.File.Move(oldname, newname);
