Açıklamalar

Dikkat

WebRequest, HttpWebRequest, ServicePointve WebClient kullanım dışıdır ve bunları yeni geliştirme için kullanmamalısınız. Bunun yerine HttpClient kullanın.

ServicePoint sınıfı, kaynağın Tekdüzen Kaynak Tanımlayıcısı'nda (URI) geçirilen konak bilgilerine göre bir İnternet kaynağına bağlantıları işler. Kaynakla ilk bağlantı, ServicePoint nesnesinin koruduğu bilgileri belirler ve daha sonra bu kaynağa yönelik sonraki tüm istekler tarafından paylaşılır.

ServicePoint nesneleri ServicePointManager sınıfı tarafından yönetilir ve gerekirse ServicePointManager.FindServicePoint yöntemiyle oluşturulur. ServicePoint nesneleri hiçbir zaman doğrudan oluşturulmaz ancak her zaman ServicePointManager sınıfı tarafından oluşturulur ve yönetilir. Oluşturulabilecek en fazla ServicePoint nesne sayısı, ServicePointManager.MaxServicePoints özelliği tarafından ayarlanır.

Her ServicePoint nesnesi, MaxIdleTime özelliğinde belirtilen süreden daha uzun süre boşta kalana kadar bir İnternet kaynağıyla bağlantısını korur. bir ServicePointMaxIdleTime değerini aştığında, başka bir bağlantıya geri dönüştürülebilir. varsayılan MaxIdleTime değeri ServicePointManager.MaxServicePointIdleTime özelliği tarafından ayarlanır.

ConnectionLeaseTimeout özelliği -1 dışında bir değere ayarlandığında ve belirtilen süre geçtikten sonra, bir sonraki isteği karşıladıktan sonra etkin bir ServicePoint bağlantısı kapatılır. Bu, varsayılan olarak olduğu gibi süresiz olarak açılan etkin bağlantılar gerektirmeyen uygulamalar için kullanışlıdır.

Not

Yüksek yük koşullarında, bazı uygulamalarda ThreadPool'da boş iş parçacıkları tükenebilir ve bu da sistem performansının düşmesine (yüksek ve değişken işlem süreleri gibi) yol açabilir.
