录播教室预约系统(六)-注册新用户
预约系统中，新用户可以自己注册，然后管理员开通。
注册界面如下：
客户端新用户注册代码：
private void button1_Click(object sender, EventArgs e) { if(txtUserID.Text.Trim ()==""|| txtUserName.Text.Trim ()=="") { MessageBox.Show ("用户名ID 和用户名不能为空"); return ; } //声明一个用户类 Users registerUser = new Users(); registerUser.UserID = txtUserID.Text.Trim(); registerUser.Name = txtUserName.Text.Trim(); registerUser.Department = cmbSchoolList.Text;
//声明一个初始密码，如果用户用此密码登陆，服务器可识别为未开通用户 registerUser.Password = "msdcmsdcmsdcmsdcmsdc";
//把实体类发送个客户端，并获取返回的结果 ResMessage resMessage = newTcpConnection.SendReceiveObject<ResMessage>("ReqRegUser", "ResRegUser", 5000, registerUser); if (resMessage.Message == "操作成功") { MessageBox.Show("新用户注册成功，请等待学校管理员审核，审核通过后初始密码为 123456"); this.Close(); } else { MessageBox.Show("出现错误，错误信息为:" + resMessage.Message); } }
服务器端的相关处理代码：
构造函数中声明：
//注册新用户 NetworkComms.AppendGlobalIncomingPacketHandler<Users>("ReqRegUser", HandlRegUser);
处理方法
private void HandlRegUser(PacketHeader header, Connection connection, Users Users) { string userID = Users.UserID; Users oldUser =DoUsers.GetUserByID(userID); // =-1代表不存在相关记录 if (oldUser.Id == -1) { DoUsers.Save(Users); ResMessage resMessage = new ResMessage("操作成功"); connection.SendObject("ResRegUser", resMessage); } else { ResMessage resMessage = new ResMessage("用户ID已经存在"); connection.SendObject("ResRegUser", resMessage); } }
DoUsers.GetUserByID方法
public static Users GetUserByID(string userID) { using (IDataReader reader = DBUsers.GetOneByUserID(userID)) { Users theUser = PopulateFromReader(reader); return theUser; } }
DoUsers中的Save方法
public static bool Save(Users Users) { if (Users.Id > 0) { return Update(Users); } else { return Create(Users); } }
Update和Create方法
private static bool Create(Users Users) { int newID = 0; newID = DBUsers.Create( Users.UserID, Users.Name, Users.Password, Users.Declaring, Users.Status, Users.IsMale, Users.UserLevel, Users.Enabled, Users.RegisterTime, Users.LastLoginTime, Users.DepID, Users.Department); Users.Id = newID; return (newID > 0); } /// <summary> /// Updates this instance of Users. Returns true on success. /// </summary> /// <returns>bool</returns> private static bool Update(Users Users) { return DBUsers.Update( Users.Id, Users.UserID, Users.Name, Users.Password, Users.Declaring, Users.Status, Users.IsMale, Users.UserLevel, Users.Enabled, Users.RegisterTime, Users.LastLoginTime, Users.DepID, Users.Department); }
DBUsers类
public static class DBUsers { /// <summary> /// Gets the connection string for read. /// </summary> /// <returns></returns> private static string GetReadConnectionString() { return ConfigurationManager.AppSettings["MSSQLConnectionString"]; } /// <summary> /// Gets the connection string for write. /// </summary> /// <returns></returns> private static string GetWriteConnectionString() { if (ConfigurationManager.AppSettings["MSSQLWriteConnectionString"] != null) { return ConfigurationManager.AppSettings["MSSQLWriteConnectionString"]; } return ConfigurationManager.AppSettings["MSSQLConnectionString"]; } /// <summary> /// Inserts a row in the RcUsers table.
