StreamSocketListener.ConnectionReceived 活动
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
指示在 StreamSocketListener 对象上收到连接的事件。
// Register
event_token ConnectionReceived(TypedEventHandler<StreamSocketListener, StreamSocketListenerConnectionReceivedEventArgs const&> const& handler) const;
// Revoke with event_token
void ConnectionReceived(event_token const* cookie) const;
// Revoke with event_revoker
StreamSocketListener::ConnectionReceived_revoker ConnectionReceived(auto_revoke_t, TypedEventHandler<StreamSocketListener, StreamSocketListenerConnectionReceivedEventArgs const&> const& handler) const;public event TypedEventHandler<StreamSocketListener,StreamSocketListenerConnectionReceivedEventArgs> ConnectionReceived;function onConnectionReceived(eventArgs) { /* Your code */ }
streamSocketListener.addEventListener("connectionreceived", onConnectionReceived);
streamSocketListener.removeEventListener("connectionreceived", onConnectionReceived);
- or -
streamSocketListener.onconnectionreceived = onConnectionReceived;Public Custom Event ConnectionReceived As TypedEventHandler(Of StreamSocketListener, StreamSocketListenerConnectionReceivedEventArgs) 事件类型
注解
若要侦听 StreamSocketListener 对象上的连接，应用必须将 ConnectionReceived 事件分配给事件处理程序，然后调用 BindEndpointAsync 或 BindServiceNameAsync 方法，将 StreamSocketListener 绑定到要侦听的本地服务名称或 TCP 端口。 若要侦听蓝牙 RFCOMM，绑定是蓝牙服务 ID。
注意 从 StreamSocket 的角度来看，并行模式库（PPL）完成处理程序在执行（并且套接字符合处置条件）后，继续正文运行。 因此，若要防止套接字在延续中使用套接字，则需要使用 C++ PPL 延续中对 StreamSocket 的引用中所述的方法之一。
