【C#】机房重构—修改密码

【前言】

在七层登录的 基础上进行登录用户的密码修改。

【实现】

代码片

UI

 public void btnOk_Click(object sender, EventArgs e)
        {
            if (txtOldPWD.Text.Trim().Length == 0 || txtNewPWD.Text.Trim().Length == 0 || txtCheckPWD.Text.Trim().Length == 0)
            {
                MessageBox.Show("请输入完整！","");
                return;
            }
            if (txtNewPWD.Text.Trim() != txtCheckPWD.Text.Trim())
            {
                MessageBox.Show("两次密码输入不一致，请重新输入！");
                return;
            }
            if (txtOldPWD.Text != frmLogin.PassWord)
            {
                MessageBox.Show("原密码输入错误，请重新输入", "提示");
                return;
            }
            else
            {
                LoginFacade Facade = new LoginFacade();
                Entity.AdUserInfo user = new AdUserInfo();
                user.UserID = frmLogin.UserID;
                user.PassWord = txtNewPWD.Text;
                Boolean result = false;
                UpDateUserPWD updateuserpwd = new UpDateUserPWD();
                result = updateuserpwd.UpDateUserpwd(user);
                if (result != false)
                {

                    MessageBox.Show("操作错误！", "提示");
                    txtCheckPWD.Clear();
                    txtNewPWD.Clear();
                    txtOldPWD.Clear();
                }
                else
                {
                    MessageBox.Show("修改成功", "提示");
                    txtCheckPWD.Clear();
                    txtNewPWD.Clear();
                    txtOldPWD.Clear();
                }
            }

DAL

 public   class ChangePWD :IDAL.PassWordIDAL
    {
        public int UpDateUser(AdUserInfo UserInfo)
        {
            SQLHelper sqlhelper = new SQLHelper();
            SqlParameter[] sqlParams =
                { new SqlParameter("@userID", UserInfo.UserID),
                    new SqlParameter("@PassWord", UserInfo.PassWord) };
            string sql = @"update T_User set PWD=@Password where userID =@userID ";
            int res = sqlhelper.ExecuteNonQuery(sql, sqlParams, CommandType.Text);
            return res;

BLL

 public   class ChangePWD :IDAL.PassWordIDAL
    {
        public int UpDateUser(AdUserInfo UserInfo)
        {
            SQLHelper sqlhelper = new SQLHelper();
            SqlParameter[] sqlParams =
                { new SqlParameter("@userID", UserInfo.UserID),
                    new SqlParameter("@PassWord", UserInfo.PassWord) };
            string sql = @"update T_User set PWD=@Password where userID =@userID ";
            int res = sqlhelper.ExecuteNonQuery(sql, sqlParams, CommandType.Text);
            return res;

Facade

 public  class UpDateUserPWD
    {
            public Boolean UpDateUserpwd(Entity.AdUserInfo User)
            {
                bool flag;
                BLL.ChangePWDBLL userBLL = new BLL.ChangePWDBLL();
                flag = userBLL.UserPassWord(User);
                return flag;
            }
        }

【收获】

还有接口跟工厂的就不贴出来了，自己在这一段时间为了个这个这的是头疼啊。
想想还是先辈说的对“实践是检验真理的唯一标准！！！”
加油吧，少年！
