How do I Bind the enum value in MVC3 to select the correct one?

In ASP.NET MVC3 I think it has got to be a known problem, and I just haven't found the correct answer to my problem.

I have an enum something like this

public enum CardType
{
    [Description( "" )]
    None = 0,

    Visa = 1,

    Mastercard = 2,

    Discover = 3,

    [Description( "Americ开发者_JAVA技巧an Express" )]
    AmericanExpress = 4
}

Now the correct term would to be something like this which is being pulled from a table in the database, because I only get certain card types that I have enabled right now. Which we only have Visa/Mastercard

<select name="CardType" id="CardType">
    <option value="1">Visa</option>
    <option value="2">Mastercard</option>
</select>

Now lets say I want Mastercard to be defaulted selected. I have to do something like this

CardTypes = new List<SelectListItem>();
var ctypes = db.ExecuteReaderDynamic( "CardType_GetAll", null, System.Data.CommandType.StoredProcedure )
      .Select( d =>
        new SelectListItem
    {
        Text = d.Name,
        Value = d.ID.ToString()
                    Selected = (d.ID == (int)CardType)
    } );
CardTypes.AddRange( ctypes );

Now I don't have a problem with this part, which is not always not promising to work. Sometimes it will pass "Mastercard" instead of the number value passed... I am confused on how to fix this... Only a few solutions which I don't want to use if I can help it because it just means more work...

I'm kinda confused what you are doing with this, I don't really understand.

 Selected = (d.ID == (int)CardType)

You get the ID and check it against the Enum CardType? Doesn't this give the following error:

CardType' is a 'type' but is used like a 'variable'

Shouldn't this work?

CardTypes = new List<SelectListItem>();
var ctypes = db.ExecuteReaderDynamic( "CardType_GetAll", null, System.Data.CommandType.StoredProcedure )
      .Select( d =>
        new SelectListItem
    {
        Text = d.Name,
        Value = d.ID.ToString()
                    Selected = false
    } );
CardTypes.AddRange( ctypes );

SelectList oCards = new SelectList(oCardTypes, (int)CardType.Mastercard);

And use the oCards directly into your combobox?
