Creating a populated dropdownlist with items in the view

I'm trying to create a dropdownlist that contains a list of items:

@Html.DropDownList("displayCount", new SelectList(        
    new[]
    {
        new SelectListItem { Value = "25", Text = "25" },
        new SelectListItem { Value = "50", Text = "50" },
        new SelectListItem { Value = "100", Text = "100" },
    }
));

When I look at my dropdownlist, it just has 3 options that say "System.Web.Mvc.SelectListItem"

What do I need to do differently here?

The reason why you got "System.Web.Mvc.SelectListItem" listed in your dropdown is because you didn't specify which attribute of the List Item you want to use for the Text and Value of the dropdown list. Right now, it is being displayed based on the .ToString() of each item in the list, which returns the full name of the SelectListItem class

@Html.DropDownList("displayCount", new SelectList(        
    new[]
    {
        new SelectListItem { Value = "25", Text = "25" },
        new SelectListItem { Value = "50", Text = "50" },
        new SelectListItem { Value = "100", Text = "100" },
    },
    "Value",
    "Text"
));

Try:

@Html.DropDownList("displayCount", new SelectList(        
    new[]
    {
        new SelectListItem { Value = "25", Text = "25" },
        new SelectListItem { Value = "50", Text = "50" },
        new SelectListItem { Value = "100", Text = "100" },
    },
    "Value",
    "Text"
));

You need to tell the SelectList what fields to use:

new SelectList(..., "Value", "Text")
