copyC＃でファイル同期プログラムを作成しているときに、メソッドを使用するLocalFileItemクラスのメソッドを作成しようとしました。System.IO.File.Copy(destination.Path, Path, true)ここPathで、はstringです。
このコードを宛先で実行した後。Path = "C:\\Test2"また、 C：\ Testthis.Path = "C:\\Test\\F1.txt"でこの操作を実行するために必要なファイル権限がないという例外が発生しますが、C：\ Testは自分自身（現在のユーザー）が所有しています。
誰かが何が起こっているのか、またはこれを回避する方法を知っていますか？
これが完全な元のコードです。
