ServicePointManager.MaxServicePointIdleTime 属性

定义

命名空间:

System.Net

程序集:

System.Net.ServicePoint.dll

Source:

ServicePointManager.cs

获取或设置 ServicePoint 对象的最大空闲时间。

public:
 static property int MaxServicePointIdleTime { int get(); void set(int value); };

public static int MaxServicePointIdleTime { get; set; }

static member MaxServicePointIdleTime : int with get, set

Public Shared Property MaxServicePointIdleTime As Integer

属性值

Int32

ServicePoint 对象的最大空闲时间（以毫秒为单位）。 默认值是 100,000 毫秒（100 秒）。

例外

ArgumentOutOfRangeException

MaxServicePointIdleTime 小于 Infinite 或大于 Int32.MaxValue。

示例

下面的代码示例设置此属性。

// 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

注解

属性MaxServicePointIdleTime设置对象在创建ServicePoint对象时分配给 MaxIdleTime 属性的最长空闲时间ServicePointManager。 对此值的更改仅 ServicePoint 影响在值更改后初始化的对象。

对象 ServicePoint 在 中指定的 MaxIdleTime时间处于空闲状态后，它有资格进行垃圾回收。 ServicePoint当与对象关联的连接列表为空时，ServicePoint对象处于空闲状态。
