VB FileSystem.Copy - どのように名前を変更したファイル

Question

の新しい名前を取得する私はプログラムディレクトリにファイルをコピーするには、この機能を使用しています：

new Computer().FileSystem.CopyFile(source, 
            destination, 
            UIOption.AllDialogs, 
            UICancelOption.ThrowException); 

ファイルが同じ名前で存在する場合、ユーザー新しい名前で置き換え、キャンセル、またはコピーを要求する通常のウィンドウダイアログが表示されます。

そのファイルの新しい名前を返すことはありますか？

は、私はあなたが後にしている何がそれはこのcodeを見つけ、私の解釈は、C＃で使用すると、ファイルが既に存在していないことを確認していないのはなぜけれども...
