Public Shared Property MaxServicePoints As Integer

Wartość właściwości

Int32

Maksymalna liczba obiektów do utrzymania ServicePoint . Wartość domyślna to 0, co oznacza, że nie ma limitu ServicePoint liczby obiektów.

Przykłady

Poniższy przykład kodu ustawia tę właściwość.

// Set the maximum number of ServicePoint instances to 
// maintain. If a ServicePoint instance for that host already 
// exists when your application requests a connection to
// an Internet resource, the ServicePointManager object
// returns this existing ServicePoint instance. If none exists 
// for that host, it creates a new ServicePoint instance.
ServicePointManager::MaxServicePoints = 4;

// Set the maximum idle time of a ServicePoint instance to 10 seconds.
// After the idle time expires, the ServicePoint object is eligible for
// garbage collection and cannot be used by the ServicePointManager.
ServicePointManager::MaxServicePointIdleTime = 10000;

// Set the maximum number of ServicePoint instances to
// maintain. If a ServicePoint instance for that host already
// exists when your application requests a connection to
// an Internet resource, the ServicePointManager object
// returns this existing ServicePoint instance. If none exists
// for that host, it creates a new ServicePoint instance.
ServicePointManager.MaxServicePoints = 4;

// Set the maximum idle time of a ServicePoint instance to 10 seconds.
// After the idle time expires, the ServicePoint object is eligible for
// garbage collection and cannot be used by the ServicePointManager object.
ServicePointManager.MaxServicePointIdleTime = 10000;

' Set the maximum number of ServicePoint instances to maintain.
' Note that, if a ServicePoint instance for that host already 
' exists when your application requests a connection to
' an Internet resource, the ServicePointManager object
' returns this existing ServicePoint. If none exists 
' for that host, it creates a new ServicePoint instance.
ServicePointManager.MaxServicePoints = 4

' Set the maximum idle time of a ServicePoint instance to 10 seconds.
' After the idle time expires, the ServicePoint object is eligible for

ServicePointManager.MaxServicePointIdleTime = 10000

Uwagi

Gdy zmniejszasz MaxServicePoints właściwość poniżej liczby ServicePoint obiektów, które obecnie istnieją, ServicePointManager obiekt usuwa ServicePoint obiekty z najdłuższym czasem bezczynności. Jeśli liczba ServicePoint obiektów z aktywnymi połączeniami jest większa niż wartość MaxServicePoints, ServicePointManager obiekt usuwa ServicePoint obiekty w miarę ich bezczynności.
