Question

i have a Class called “Services” in the App_code folder that contain Method like this:

public static ???? GetAllCustomers()
{
    string conn = ConfigurationManager.ConnectionStrings["ConnectToDB"].ConnectionString;

    using (SqlConnection connection= new SqlConnection(conn))
    {
        using (SqlCommand cmd = new SqlCommand())
        {
            cmd.CommandText = "select C_ID,L_ID,C_Name from Customer";
            cmd.Connection = connection;
            connection.Open();
            ????
            ????
        }
    }
    return  ???;

what should i use in the “????” as return type…because i want to bind dropdownbox.datasource to ???? and use the datavaluefield and datatextfield..
so should i make the method return datatable class or something else..
i hope i made my question clear..

Answer 1

You can return a System.Data.DataTable and use column names for datatextfield and datavaluefield.
