当我在配置文件中填写userdeatils onece然后注销并再次登录时，用户配置文件为空 [英] when i fill userdeatils onece in profile then logout and log in again then user profile is empty

问题描述

嘿所有



i有一个问题，当用户通过用户名和密码登录后，



他/她去他/她的个人资料并填写他们的信息

即姓名，电子邮件地址和phonenumebr

然后他登录并填写信息然后他/她退出



然后当他/她再次登录并查看他/她的个人资料然后他的个人资料是空的

  protected   void  Button1_Click1（ object  sender，EventArgs e）
 {
 
 
  try  
 {
 cg.updateuser（Convert.ToInt32（Session [  UserID]） ，TextBox1.Text，TextBox2.Text，TextBox3.Text）; 
  //   Label14.Text = TextBox1.Text ++ TextBox2.Text ++ TextBox3。文字;  
} 
  catch  
 {
 Label14.Text =（ 成功更新）; 
} 
 Label1 .Text = Convert.ToString（TextBox1.Text +  ）; 
 Label2.Text = Convert.ToString（TextBox2.Text +  ）; 
 Label15.Text = Convert.ToString（TextBox3.Text +  ）; 
 
 
} 
 
 受保护  void  Button6_Click（ object  sender，EventArgs e）
 {
 TextBox1.Visible =  true ; 
 TextBox2.Visible =  true ; 
 TextBox3.Visible =  true ; 
 Label1.Visible =  false ; 
 Label2.Visible =  false ; 
 Label15.Visible =  false ; 
 
  try  
 {
 cg.updateuser（Convert.ToInt32（Session [  UserID]），TextBox1.Text，TextBox2.Text，TextBox3.Text）; 
 Label14.Text = TextBox1.Text +   + TextBox2.Text +   + TextBox3.Text; 
} 
  catch  
 {
 Label14.Text =（ 成功）; 
} 
} 
 

按钮1是编辑按钮代码和按钮6是更新代码

解决方案

嗯。您确实知道到达报告成功的点的唯一方法是 出现问题，并且操作失败，抛出异常？

 尝试 
 {
  //  某些可能有效或无效的代码 
} 
  catch  
 {
  //  异常时来到这里因为出现问题而被抛出。 
} 

hey all

when user log in through theri username and password then after this
he/she go to his/her profile and fill their info
i.e FUll name ,email address and phonenumebr
then one he login adn fill info then he/she logout

then when he/she once again log in and see his/her profile then his.her profile is empty

protected void Button1_Click1(object sender, EventArgs e)
       {


           try
           {
               cg.updateuser(Convert.ToInt32(Session["UserID"]),TextBox1.Text, TextBox2.Text, TextBox3.Text);
               //Label14.Text = TextBox1.Text + "" + TextBox2.Text + "" + TextBox3.Text;
           }
           catch
           {
               Label14.Text = ("Updated Succesfully");
           }
           Label1 .Text= Convert.ToString(TextBox1.Text + "");
           Label2.Text = Convert.ToString(TextBox2.Text+"");
           Label15.Text = Convert.ToString(TextBox3.Text+"");


       }

       protected void Button6_Click(object sender, EventArgs e)
       {
           TextBox1.Visible = true;
           TextBox2.Visible = true;
           TextBox3.Visible = true;
           Label1.Visible = false;
           Label2.Visible = false;
           Label15.Visible = false;

           try
           {
               cg.updateuser(Convert.ToInt32(Session["UserID"]), TextBox1.Text, TextBox2.Text, TextBox3.Text);
               Label14.Text = TextBox1.Text + "" + TextBox2.Text + "" + TextBox3.Text;
           }
           catch
           {
               Label14.Text = ("Success");
           }
       }

button 1 is edit button code and button 6 is update code

解决方案

Um. You do realize that the only way to get to the points where you report "success" is when there has been a problem, and the operation has failed, throwing an exception?

try
   {
   // some code which may or may not work
   }
catch
   {
   // Comes here when an exception is thrown because there was a problem.
   }
