the problem is that when i am sending the request to server from local system without debugging, the code is running perfectly, but when i debug the code it is throwing the following exception
"Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack"
and not getting the required result.
How to resolve the issue


I am attaching the code:

using (System.IO.StreamReader sr =new System.IO.StreamReader(objResponse.GetResponseStream()))
                {
                    TranResponse = sr.ReadToEnd();

                    string[] ErrorCheck = GetStringInBetween(TranResponse, "!", "!-", false, false);//This line will find Error Keyword in TranResponse

                    if (ErrorCheck[0]!= "ERROR")//This block will check for Error in TranResponce
                    {
                            // Merchant MUST map (update) the Payment ID received with the merchant Track Id in his database at this place.
                            string payid=TranResponse.Substring(0,TranResponse.IndexOf(":http"));
                            string payURL=TranResponse.Substring(TranResponse.IndexOf("http"));
                            // here redirecting the customer browser from ME site to Payment Gateway Page with the Payment ID
                            string TranRedirect=payURL+"?PaymentID="+payid;
                            //sql = "insert into onlinepay values('" + name + "','" + email + "','" + payid + "','" + TranTrackid + "','" + TranAmount + "','" + DateTime.Today.Date + "','N')";
                            //con.InsertData(sql);
                            sql = "insert into onlinepay values('" + registration + "','90002752','" + TranTrackid + "','" + payid + "','" + name + "','" + email + "','" + TranAmount + "','" + DateTime.Today.Date + "','Transaction in Progress','')";
                            con.InsertData(sql);
                            Response.Redirect(TranRedirect);
                    }
                    else
                    {


                        string TranErrorUrl = "http://test.conferencepacific.ac.in/FailedTRAN.aspx?Message=Transaction Failed&ResTrackId=" + TranTrackid + "&ResAmount=" + TranAmount + "&ResError=" + TranResponse;
                            // here redirecting the error page
                            Response.Redirect(TranErrorUrl);
                    }

                }
