static member MaxServicePointIdleTime : int with get, set

Public Shared Property MaxServicePointIdleTime As Integer

屬性值

Int32

ServicePoint 物件的最大閒置時間，以毫秒為單位。 預設值為 100,000 毫秒 (100 秒)。

範例

下列程式代碼範例會設定這個屬性。

// 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
' garbage collection and cannot be used by the ServicePointManager.
ServicePointManager.MaxServicePointIdleTime = 10000

備註

屬性MaxServicePointIdleTime會設定物件在建立ServicePoint物件時指派給MaxIdleTime屬性的最大空閒時間ServicePointManager。 對此值所做的變更只會 ServicePoint 影響值變更之後初始化的物件。

ServicePoint物件在 中指定的MaxIdleTime時間閑置之後，它就有資格進行垃圾收集。 ServicePoint當與 對象相關聯的ServicePoint連接清單是空的時，物件就會閑置。
