Açıklamalar

Ortak dil çalışma zamanındaki zaman uyumsuz tasarım deseni, zaman uyumsuz yöntem çağırmayı başlatmak için bir Begin yöntem ve çağırmayı tamamlamak için bir End yöntem çağırmayı içerir. yöntemi, Begin yöntemin zaman uyumlu sürümü tarafından tanımlanan parametrelerin yanı sıra iki ek parametre alır: biri temsilciyi depolamak ve diğeri de temsilciye geçirilmesi gereken durum bilgilerini depolamak için. Bu özellik, parametre adı olan temsilcinin parametresini AsyncCallbacktemsil eder.
