Rendering error using SelectList from manually defined SelectListItems in MVC 2

Question

I am using ASP.NET MVC 2 (.NET 3.5) and I need to manually determine what the list of options should be. When I do this, I get a drop-down menu, with each of the manual entries reading "System.Web.Mvc.SelectListItem".

My view model defines a list as such:

    public SelectList YesNoList
    {
      get
      {
        List<SelectListItem> tmpList = new List<SelectListItem>();
        tmpList.Add(new SelectListItem {Text = "", Value = ""});
        tmpList.Add(new SelectListItem {Text = "Yes", Value = "1"});
        tmpList.Add(new SelectListItem {Text = "No", Value = "0"});
        YesNoList = new SelectList(tmpList,"");
      }
      private set{}
     }

In the view, I reference this with an Html.DropDownList:

Html.DropDownList("FieldName", viewmodel.YesNoList);

What I expect to get on the last web page should look like this:

<select id="FieldName" name="FieldName">
  <option value=""/>
  <option value="1">Yes</option>
  <option value="0">No</option>
</select>

Instead, I get:

<select id="FieldName" name="FieldName">
  <option>System.Web.Mvc.SelectListItem</option>
  <option>System.Web.Mvc.SelectListItem</option>
  <option>System.Web.Mvc.SelectListItem</option>
</select>

Try this code:

OdbcDataReader iLRt1 = databaseFunctions.databaseConnection.getFromDatabaseReader("select * from groups order by head");

List<SelectListItem> Hello1 = new List<SelectListItem>();
Hello1.Add(new SelectListItem { Text = "Select All", Value = "Select All" });

while (iLRt1.Read())
{
    Hello1.Add(new SelectListItem { Text = iLRt1["head"].ToString(), Value = iLRt1["code"].ToString() });}

ViewData["myList2"] = Hello1;
