Selected value for dropdown list for mvc4

Question

I created a ViewBag selection list in the Edit action and set the value to be selected as:

ViewBag.Doors = new SelectList( new[] { new {ID = 1, Name="1-Door"}, new {ID = 2, Name="2-Doors"}, new {ID = 3, Name="3-Doors"}, new {ID = 4, Name="4-Doors"}, new {ID = 5, Name="5-Doors"}, new {ID = 6, Name="6-Doors"}, new {ID = 7, Name="7-Doors"} }, "ID", "Name", advert.Doors); 

But in the view, the value for the drop-down menu is not selected by default.

My view code:

 @Html.DropDownListFor(model => model.Doors, (SelectList)ViewBag.Doors, "--Select--") @Html.ValidationMessageFor(model => model.Doors) 

The Door property will be numeric 1,2,3, ..
