急急如律令！火速搭建一个即时通讯系统！（附源码分享——高度可移植！） - CXLian(3)_H5之家

1.客户端发送登陆消息

private void button_login_Click(object sender, EventArgs e) { this.selfID = this.textBox_ID.Text.Trim(); LoginMsg loginMsg = new LoginMsg(this.selfID); this.tcpPassiveEngine.PostMessageToServer(loginMsg.ToContractStream()); }

2.服务端回复登陆消息

1 if (msgType == MsgType.Logining) 2 { 3 LoginMsg loginMsg = MsgHelper.DeserializeMsg<LoginMsg>(msg); 4 this.ReplyLogining(loginMsg, userAddress); .TellOtherUser(MsgType.NewOnlineFriend, loginMsg.SrcUserID); 7 } 回复登陆消息 ReplyLogining(LoginMsg loginMsg, IPEndPoint userAddress) 15 { { 18 loginMsg.LogonResult = LogonResult.Repetition; 19 this.tcpServerEngine.SendMessageToClient(userAddress, loginMsg.ToContractStream()); 20 } { 23 this.AddUser(loginMsg.SrcUserID, userAddress); 24 this.ShowOnlineUserCount(); 25 loginMsg.LogonResult = LogonResult.Succeed; 26 this.tcpServerEngine.SendMessageToClient(userAddress, loginMsg.ToContractStream()); 27 } 28 }

3.客户端处理登陆结果

tcpPassiveEngine_MessageReceived(IPEndPoint userAddress, byte[] msg) 2 { msgType = BitConverter.ToInt32(msg, 0); (msgType == MsgType.Logining) 7 { 8 LoginMsg loginMsg = MsgHelper.DeserializeMsg<LoginMsg>(msg); 9 if (loginMsg.LogonResult == LogonResult.Succeed) 10 { 11 this.DialogResult = DialogResult.OK; 12 this.tcpPassiveEngine.MessageReceived -= new StriveEngine.CbDelegate<IPEndPoint, byte[]>(tcpPassiveEngine_MessageReceived); 13 } 14 if (loginMsg.LogonResult == LogonResult.Repetition) 15 { ); 17 } 18 } 19 }
