录播教室预约系统(七)-客户端更改密码
界面如下：
客户端代码：
//用这2个属性映射新密码和旧密码 //原密码 this.currentUser.Password = textBox1.Text.Trim(); //新密码 this.currentUser.NewPassword = textBox2.Text.Trim(); //把带有密码信息的契约类 currentUser发送到服务器端，并获取返回结果 ResMessage resMessage = newTcpConnection.SendReceiveObject<ResMessage>("ChangePassword", "ResChangePassword", 5000, this.currentUser); if (resMessage.Message == "操作成功") { MessageBox.Show("密码更新成功"); } else { MessageBox.Show("出现错误，错误原因为：" + resMessage.Message); }
服务器端代码：
在构造函数中声明更改密码的处理方法：
//用户更改密码 NetworkComms.AppendGlobalIncomingPacketHandler<Users>("ChangePassword", HandleChangePassword);
服务器端的处理方法：
private void HandleChangePassword(PacketHeader header, Connection connection, Users theUser) {
//首先从数据库中获取相应的用户 Users currentUser = DoUsers.GetUserByID(theUser.UserID); ResMessage resMessage = new ResMessage(); resMessage.Message = "出现未知错误"; //判断原密码是否正确 if (currentUser.Password == theUser.Password) {
//如果原密码正确，则设置新密码 currentUser.Password = theUser.NewPassword; DoUsers.Save(currentUser); resMessage.Message = "操作成功"; } else { resMessage.Message = "原密码不正确"; } //把获取到的数据发回去 connection.SendObject("ResChangePassword", resMessage); }
数据库操作类：
