Nasıl yapılır: Yalıtılmış Depolamadaki Depoları Silme

sınıfı yalıtılmış IsolatedStorageFile depolama dosyalarını silmek için iki yöntem sağlar:

• Örnek yöntemi Remove() hiçbir bağımsız değişken almaz ve onu çağıran depoyu siler. Bu işlem için izin gerekmez. Depoya erişebilen tüm kodlar içindeki verileri veya tüm verileri silebilir.

• Statik yöntem Remove(IsolatedStorageScope) numaralandırma değerini alır User ve kodu çalıştıran kullanıcının tüm depolarını siler. Bu işlem, değer için AdministerIsolatedStorageByUser izin gerektirirIsolatedStorageFilePermission.

Örnek

Aşağıdaki kod örneği, statik ve örnek Remove yöntemlerinin kullanımını gösterir. sınıfı iki depo alır; biri kullanıcı ve derleme için, diğeri ise kullanıcı, etki alanı ve derleme için yalıtılır. Kullanıcı, etki alanı ve derleme deposu, yalıtılmış depolama dosyasının Remove()isoStore1yöntemi çağrılarak silinir. Ardından, kullanıcı için kalan tüm depolar statik yöntemi Remove(IsolatedStorageScope)çağrılarak silinir.
