This is not even a correct English phrase, so, it's really hard to understand what are you talking about. Perhaps you should try your questions on your colleagues and post them only if someone would understand something. Put a lot more detail, provide comprehensive explanation of your goal and your concerns. "Improve questions" is above.

Hello

i think u want to do is something like

u have

1 - database
2 - Class for fetching data using query or stored procedure
3 - form to display questions .

make One function in Class for having all data from database
get all that data on form using class object and save it in one List<class>

add datasource to the control on which you want to display you data .

good luck ..

what you did cannot iterate because foreach loop iterate on enumerable type .
and your object will not have all data .it will contain only last item from the database .

so for getting all data you will need to add object in a class type List after that you can use for each loop on the List

While creating class for the Question we should store the Questions in a list.
From the list of questions we can use foreach loop and display each question one by one..

C#

{
       dt =HttpContext.Current.Session["Answered"] as DataTable;
       foreach(DataRow row in dt.Rows)
       {
           if(row["Id"].ToString()==Label2.Text)
           {
               row["Selected"]=Convert.ToInt32(RadioButtonList1.SelectedIndex)+1;
               HttpContext.Current.Session["Result"] = dt;
           }
       }
       dt = HttpContext.Current.Session["Result"] as DataTable;
       foreach (DataRow row in dt.Rows)
       {
           if (row["Selected"].ToString() == row["CorrectOption"].ToString())
           {
               marks = marks + 1;
           }
       }
       HttpContext.Current.Session["Marks"] = marks;
   }
