Asp.net Response.Redirect

Question

我在删除特定用户后使用response.redirect以使用最新值填充网格..但它给了我错误 lblError.Text =无法计算表达式，因为代码已优化或本机框位于调用堆栈之上。

因为这个错误我没有得到删除的确认任何帮助将不胜感激

代码： -   if（chk.Checked == true）                         {

                        isDeleted=oFTE.DeleteUserRoleMapDetails(row.Cells[1].Text);
                        if (isDeleted == 0)
                        {
                            lblError.Visible = true;
                            lblError.ForeColor = System.Drawing.Color.Red;
                            lblError.Text = "User Role Map deletion failed.";
                        }
                        else if (isDeleted == 1)
                        {
                            lblError.Visible = true;
                            lblError.ForeColor = System.Drawing.Color.Red;                                
                            //Response.Redirect("userRoleMap.aspx");
                            Session["Msg"] = "User Role Map deleted successfully.";
                            Response.Redirect("userRoleMap.aspx",false);

                           //lblError.Text = "User Role Map deleted successfully.";                                 
                            break;
                        }                                                     
                    }

                    if (iRowCount == gridViewResults.Rows.Count)
                    {
                        lblError.Visible = true;
                        lblError.ForeColor = System.Drawing.Color.Red;
                        lblError.Text = "Please select a row to delete.";
                    }
                }
            }
        }
        catch (Exception ex)
        {
            lblError.Visible = true;
            lblError.ForeColor = System.Drawing.Color.Red;
            lblError.Text = ex.Message.ToString();
        }           
    }      

Answer 1

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

当您在本机调用中暂停调试器时，仅显示在Locals / Watch窗口中。这不是阻止页面加载的实际错误。也许，问题是你在代码中设置了一个断点，并且在你恢复执行之前，请求是从浏览器中超时的？

Answer 2

消息来自调试器。在没有调试器的情况下运行应用程序以查看真正的错误。
