Açıklamalar

ReaderWriterLock bir kaynağa erişimi eşitlemek için kullanılır. Herhangi bir zamanda, birden çok iş parçacığı için eşzamanlı okuma erişimine veya tek bir iş parçacığı için yazma erişimine izin verir. Bir kaynağın seyrek olarak değiştirildiği bir durumda, ReaderWriterLock gibi tek seferde basit bir kilitten Monitordaha iyi aktarım hızı sağlar.

ReaderWriterLock çoğu erişimin okunduğu, yazma işlemlerinin ise seyrek ve kısa süreli olduğu durumlarda en iyi sonucu verir. Birden çok okuyucu tek yazıcılarla birlikte alternatif olarak, okuyucuların veya yazarların uzun süreler boyunca engellenmemesi için.

bir iş parçacığı bir okuyucu kilidini veya yazıcı kilidini tutabilir, ancak aynı anda ikisini birden tutamaz. Yazıcı kilidini almak için bir okuyucu kilidi bırakmak yerine ve DowngradeFromWriterLockkullanabilirsinizUpgradeToWriterLock.

Özyinelemeli kilit istekleri, kilit üzerindeki kilit sayısını artırır.

Okuyucular ve yazarlar ayrı ayrı kuyruğa alınıyor. Bir iş parçacığı yazıcı kilidini serbest bıraktığında, o anda okuyucu kuyruğunda bekleyen tüm iş parçacıklarına okuyucu kilitleri verilir; Tüm bu okuyucu kilitleri serbest bırakıldığında, varsa yazıcı kuyruğunda bekleyen bir sonraki iş parçacığına yazıcı kilidi verilir ve bu şekilde devam eder. Başka bir deyişle, ReaderWriterLock bir okuyucu koleksiyonu ile bir yazar arasında geçiş sağlar.

Yazıcı kuyruğundaki bir iş parçacığı etkin okuyucu kilitlerinin yayımlanmasını beklerken, yeni okuyucu kilitleri isteyen iş parçacıkları okuyucu kuyruğunda birikir. Mevcut okuyucu kilidi sahipleriyle eşzamanlı erişim paylaşabilseler bile istekleri verilmez; bu, yazarların okuyucular tarafından süresiz engellenmesine karşı korunmasına yardımcı olur.

Kabul edilen zaman aşımı değerlerinde ReaderWriterLock kilit alma yöntemlerinin çoğu. Uygulamanızda kilitlenmeleri önlemek için zaman aşımlarını kullanın. Örneğin, bir iş parçacığı bir kaynakta yazıcı kilidini alabilir ve ardından ikinci bir kaynakta okuyucu kilidi isteyebilir; bu arada, başka bir iş parçacığı ikinci kaynakta yazıcı kilidini alabilir ve ilkinde bir okuyucu kilidi isteyebilir. Zaman aşımları kullanılmadığı sürece iş parçacıkları kilitlenmez.

Zaman aşımı aralığının süresi dolarsa ve kilit isteği verilmediyse, yöntemi bir ApplicationExceptionoluşturarak denetimi çağıran iş parçacığına döndürür. bir iş parçacığı bu özel durumu yakalayabilir ve bundan sonra hangi eylemin gerçekleştirileceğini belirleyebilir.

Zaman aşımları milisaniye cinsinden ifade edilir. Zaman aşımını belirtmek için bir System.TimeSpan kullanırsanız, kullanılan değer ile TimeSpantemsil edilen toplam milisaniye sayısıdır. Aşağıdaki tabloda geçerli zaman aşımı değerleri milisaniye cinsinden gösterilmektedir.

-1 dışında, negatif zaman aşımı değerlerine izin verilmez. -1 dışında bir negatif tamsayı belirtirseniz, bunun yerine sıfır zaman aşımı değeri kullanılır. (Yani, kilit hemen alınamazsa yöntem beklemeden döner.) -1 dışında negatif bir milisaniye sayısını temsil eden bir TimeSpan belirtirseniz, ArgumentOutOfRangeException oluşturulur.
