Ping.OnPingCompleted(PingCompletedEventArgs) 方法

定义

引发 PingCompleted 事件。Raises the PingCompleted event.

protected:
 void OnPingCompleted(System::Net::NetworkInformation::PingCompletedEventArgs ^ e);
protected void OnPingCompleted (System.Net.NetworkInformation.PingCompletedEventArgs e);
member this.OnPingCompleted : System.Net.NetworkInformation.PingCompletedEventArgs -> unit
Protected Sub OnPingCompleted (e As PingCompletedEventArgs)

参数

e
PingCompletedEventArgs

包含事件数据的 PingCompletedEventArgs 对象。A PingCompletedEventArgs object that contains event data.

注解

从类继承的类 Ping 可以重写此方法以执行其他任务,例如记录参数中包含的数据 eClasses that inherit from the Ping class can override this method to perform additional tasks, such as logging the data contained in the e parameter.

引发事件时,将通过委托调用事件处理程序。Raising an event invokes the event handler through a delegate. 有关详细信息,请参阅 处理和引发事件For more information, see Handling and Raising Events.

OnPingCompleted 方法还允许派生类对事件进行处理而不必附加委托。The OnPingCompleted method also allows derived classes to handle the event without attaching a delegate. 这是在派生类中处理事件的首选技术。This is the preferred technique for handling the event in a derived class.

继承者说明

OnPingCompleted(PingCompletedEventArgs) 在派生类中重写时,请确保调用基类的 OnPingCompleted(PingCompletedEventArgs) 方法,以便注册的委托接收事件。When overriding OnPingCompleted(PingCompletedEventArgs) in a derived class, be sure to call the base class' OnPingCompleted(PingCompletedEventArgs) method so that registered delegates receive the event.
