客户端登陆界面如下：

客户端代码：

Program.cs中NetworkComms.IgnoreUnknownPacketTypes==ConnectionInfo(,=MainFormmainForm=frmLoginloginForm=(loginForm.ShowDialog()==(loginForm.Register===

登陆窗口中的登陆按钮相关代码

privatevoidbtnLogin_Click(objectsender,EventArgse){//如果通过输入验证if(UserInputCheck()){try{//保存登录身份是否合法验证结果boolisPass=false;UserstheUser=newUsers();theUser.UserID=txtLoginName.Text.Trim();theUser.Password=txtUserPwd.Text.Trim();//发送当前登陆用户的信息给服务器，并从服务器获取返回的信息LoginResultloginResult=newTcpConnection.SendReceiveObject<LoginResult>("Login","LoginResult",5000,theUser);if(loginResult.Message=="登录成功"){//记录用户名netConfiguration.UserID=theUser.UserID;netConfiguration.Save();//初始化主窗口中的属性theUser.Department=loginResult.Department;theUser.Name=loginResult.UserName;mainForm.InitiaLize(this.newTcpConnection,theUser);//标识验证通过isPass=true;Register=5;this.DialogResult=DialogResult.OK;}//如果未通过验证if(!isPass){MessageBox.Show(loginResult.Message);}}catch(Exceptionex){ShowLoginLostToolTip(ex);}}}

User.cs实体类代码：

Users实体类，支持Protobuf.net序列化

服务器端程序的处理代码：

在服务器端构造函数中声明针对登陆操作的处理器：

//用户验证处理器NetworkComms.AppendGlobalIncomingPacketHandler<Users>("Login",HandleUserVerify);

//用户登录验证privatevoidHandleUserVerify(PacketHeaderheader,Connectionconnection,UserstheUser){LoginResultloginResult=newLoginResult();UserscurrentUser=DoUsers.GetUserByID(theUser.UserID);stringmessage;if(currentUser!=null){if(currentUser.Password==theUser.Password)message="登录成功";elseif(currentUser.Password=="msdcmsdcmsdcmsdcmsdc")message="用户未开通,请与管理员联系";elseif(currentUser.Password!=theUser.Password)message="用户名密码不匹配";elsemessage="登录不成功，原因未知";}else{message="用户不存在";}loginResult.Message=message;loginResult.Department=currentUser.Department;loginResult.UserName=currentUser.Name;connection.SendObject("LoginResult",loginResult);}

LoginResult契约类
