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

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

Cause of Error:

When we call Response.Redirect("") from try/catch block in asp.net, you will receive above error.

Example contains error:

   try

                    {

                        string strRedirectUrl = Session["ReturnUrl"].ToString();

                        Response.Redirect(strRedirectUrl);

                    }

                    catch(Exception ex)

                    {

                        Response.Redirect("Default.aspx");

                    }

Solution:

Make second argument of response.redirect("MyPage.aspx",false);

   

Example containing solution:

try

                    {

                        string strRedirectUrl = Session["ReturnUrl"].ToString();

                        Response.Redirect(strRedirectUrl,false);

                    }

                    catch(Exception ex)

                    {

                        Response.Redirect("Default.aspx");

                    }
