Examples

下面的代码示例创建一个连接到 URI www.contoso.comServicePoint 对象。The following code example creates a ServicePoint object that connects to the URI www.contoso.com.

// This example shows how to use the ServicePoint and ServicePointManager classes.
// The ServicePointManager class uses the ServicePoint class to manage connections
// to a remote host. The networking classes reuse service points for all 
// requests to a given URI. In fact, the same ServicePoint object 
// is used to issue requests to Internet resources identified by the same
// scheme identifier (for example,  HTTP) and host fragment (for example,  www.contoso.com).  
// This should improve your application performance. 
// Reusing service points in this way can help improve application performance.

Remarks

ServicePoint 类根据在资源的统一资源标识符(URI)中传递的主机信息来处理与 Internet 资源的连接。The ServicePoint class handles connections to an Internet resource based on the host information passed in the resource's Uniform Resource Identifier (URI). 与资源的初始连接将确定 ServicePoint 对象维护的信息,该信息随后由对该资源的所有后续请求共享。The initial connection to the resource determines the information that the ServicePoint object maintains, which is then shared by all subsequent requests to that resource.

ServicePoint 对象由 ServicePointManager 类管理,并根据需要由 ServicePointManager.FindServicePoint 方法创建。ServicePoint objects are managed by the ServicePointManager class and are created, if necessary, by the ServicePointManager.FindServicePoint method. 不会直接创建 ServicePoint 对象,但始终由 ServicePointManager 类创建和管理。ServicePoint objects are never created directly but are always created and managed by the ServicePointManager class. 可以创建的最大 ServicePoint 对象数由 ServicePointManager.MaxServicePoints 属性设置。The maximum number of ServicePoint objects that can be created is set by the ServicePointManager.MaxServicePoints property.

每个 ServicePoint 对象保持与 Internet 资源的连接,直到其空闲时间超过 MaxIdleTime 属性中指定的时间。Each ServicePoint object maintains its connection to an Internet resource until it has been idle longer than the time specified in the MaxIdleTime property. ServicePoint 超出 MaxIdleTime 值时,可以将其回收到其他连接。When a ServicePoint exceeds the MaxIdleTime value, it can be recycled to another connection. MaxIdleTime 的默认值由 ServicePointManager.MaxServicePointIdleTime 属性设置。The default value of MaxIdleTime is set by the ServicePointManager.MaxServicePointIdleTime property.

如果将 ConnectionLeaseTimeout 属性设置为-1 以外的值,并且在指定的时间过后,则会在服务下一个请求后关闭活动的 ServicePoint 连接。When the ConnectionLeaseTimeout property is set to a value other than -1, and after the specified time elapses, an active ServicePoint connection is closed after it services the next request. 这对于不需要无限期打开的活动连接的应用程序非常有用,因为这些应用程序默认为。This is useful for applications that do not require active connections that are opened indefinitely, as they are by default.

Note

在高负载情况下,某些应用程序可能会耗尽 ThreadPool 中的可用线程,这可能导致系统性能不佳(如高和可变事务时间)。In high load conditions, some applications may run out of free threads in the ThreadPool, which may lead to poor system performance (such as high and variable transaction times).
