wpf代码和winform中一样&＃xff0c;但是在运行时会出现

下面图中所示&＃xff0c;界面卡死。并且服务器端接收不到客户端发送的消息

}
分析在做wpf实现UDP过程中出现的问题&＃xff1a;
1、互相接收不到对方发送的消息
2、界面假死
第一个问题&＃xff1a;
因为没有在Server程序中加入委托&＃xff0c;导致UI界面中的控件无法和后台交互&＃xff0c;在服务器代码中加入委托即可&＃xff1a;

this.Dispatcher.Invoke(new Action(() &＃61;>{txtReceive.Text &＃61; type;}));Thread.Sleep(500);this.Dispatcher.Invoke(new Action(() &＃61;>{//发送信息sendData &＃61; Encoding.Unicode.GetBytes(txtSend.Text);sock.SendTo(sendData, sendData.Length, SocketFlags.None, remote);}));Thread.Sleep(500);


第二个问题&＃xff1a;
界面无响应&＃xff0c;如上图中所示&＃xff0c;这时的服务器端可以接收到客户端的消息。但是如果输入消息&＃xff0c;界面就会卡死。
因此将服务器中的代码

this.Dispatcher.Invoke(new Action(() &＃61;>{recv &＃61; sock.ReceiveFrom(revData, ref remote);string type &＃61; Encoding.Unicode.GetString(revData, 0, recv);txtReceive.Text &＃61; type;}));


修改成

recv &＃61; sock.ReceiveFrom(revData, ref remote);string type &＃61; Encoding.Unicode.GetString(revData, 0, recv);this.Dispatcher.Invoke(new Action(() &＃61;>{txtReceive.Text &＃61; type;}));


即可&＃xff0c;不知道什么原因&＃xff0c;试出来的。如果哪位仁兄愿意指导指导&＃xff0c;请赐教
