Error when I am redirecting page

Question

I am getting an error:

"Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack."

when I am redirecting my page from one to another.

I am using this code:

try
{
    Session["objtwitter"] = obj_UserDetSumit;

           Response.Redirect("TwitterLogin.aspx");


    }
    catch (Exception ex)
    {

          lblStatus.Text = "Account Creation Failed, Please Try Again";


    }

And I got a solution and I tried also this Response.Redirect("home.aspx",false); It's not throwing an error but it's also not redirecting page.

Answer 1

Try - catch creates a thread around code within it in order to catch exceptions. When you Redirect you are effectively terminating execution of the thread thus causing an error since execution ended unnaturely (though this is by design). You should not Redirect from within try-catch and if you do you should use Response.Redirect( "some url", false ); and also specifically catch ThreadAbortException.

Reference here: http://msdn.microsoft.com/en-us/library/t9dwyts4.aspx

Response.Redirect calls the Response.End, which throws a ThreadAbortException, so you'd want to change your code to:

try
{
   Response.Redirect("home.aspx"); 
}
catch(System.Threading.ThreadAbortException)
{
   // do nothing
}
catch(Exception ex)
{
   // do whatever
}
