登陆窗口中的登陆按钮相关代码

 private void btnLogin_Click(object sender, EventArgs e)
        {            // 如果通过输入验证
            if (UserInputCheck())
            {                try

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("Login", HandleUserVerify);

 //用户登录验证
        private void HandleUserVerify(PacketHeader header, Connection connection, Users theUser)
        {
            LoginResult loginResult = new LoginResult();

            Users currentUser = DoUsers.GetUserByID(theUser.UserID);            string message;            if (currentUser != null)
            {                if (currentUser.Password == theUser.Password)
                    message = "登录成功";                else if (currentUser.Password == "msdcmsdcmsdcmsdcmsdc")
                    message = "用户未开通,请与管理员联系";                else if (currentUser.Password != theUser.Password)
                    message = "用户名密码不匹配";                else
                    message = "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);

          

        }
