Asp.net Response.Redirect

Question

我在iam刪除特定用戶後使用response.redirect使網格填充最新值..但它給了我錯誤 lblError.Text =無法評估表達式，因爲代碼已優化或本地框架位於調用堆棧的頂部。

因爲這個錯誤IAM沒有得到確認刪除的任何幫助將不勝感激

代碼： - 如果（chk.Checked ==真）{

     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. 

只當您在本機呼叫中暫停調試器時，顯示在本地/監視窗口中。這不是一個實際的錯誤，防止您的網頁加載。也許，問題在於你已經在你的代碼中設置了一個斷點，並且在你恢復執行之前請求已經從瀏覽器中超時了。

Answer 2

消息來自調試器。在沒有調試器的情況下運行應用程序以查看真正的錯誤。
