Ben Path bir string olduğunu System.IO.File.Copy(destination.Path, Path, true) yöntemini kullanır LocalFileItem sınıfında bir yöntem copy yapmaya çalıştı C# bir dosya senkronizasyonu programı oluştururken.
Bu kodu hedef ile yürüttükten sonra. Path = "C:\\Test2" ve this.Path = "C:\\Test\\F1.txt" ben bir istisna ben C Bu işlemi yapmak için gerekli dosya izinlerini sahip olmadığını söyleyerek olsun: \ Testi ancak C: \ Test kendim (geçerli kullanıcı) aittir.
Neler olup bittiğini veya bunun nasıl geçeceğini bilen var mı?Hakkında Dosya izinleri
İşte orjinal kod tamamlandı.
