Using Math.Pow(2,n) to store user's selections

[KokasPapa]

Hello

I have a webform with a series of radiobuttons where a user can select which pages he will visit next after he hits a button.

I thought I'd store his selections like this:

private int SelectedSchemes()
{
 if ( rdSTEERY.Checked )
  iSelected += Convert.ToInt32(Math.Pow(2,1));
			
 if ( rdCAFEY.Checked )
  iSelected += Convert.ToInt32(Math.Pow(2,2));

 if ( rdDiscPlusY.Checked )
  iSelected += Convert.ToInt32(Math.Pow(2,3));

    .
    .
    .
    so on...
			
  return iSelected;
}

So if the user chooses yes on the first 2 radiobuttons then I'll be storing the value 6 in the database, which corresponds to the 1st and 2nd pages.
My problem is that I don't know how to translate this breaking down of this value to those webpages. Any ideas?

Thanks

Use an Enum with the flags option. This effectively allows you to name each bit, and will make your code a whole lot more readable as you can then use symbolic names rather than bit values.
