There is nothing to "correct" here other than the obvious problem that your code snippet would not compile. "Topstring" is not a valid method call unless you created a method by that name. You probably want ToString(). You have not asked a question or described any kind of a problem.

It's very simple but we will not do all your work for you.

Just retrieve the value from the database that you want and then set the Label1.Text to that value.

Your current code, which has typos, is pulling from the QueryString.

Hi,

First fetch the value from database on C# page and set the value to Label1.Text.

If you have to send on another page then you can send through QueryString then write Label1.Text = Request.QueryString["ValueField"].ToString();

Check and Confirm. If you have any confusion then you can ask me.
