MVC 2:如何使用Html.DropDownListFor?

我还不能完全确定我的lambda,但是为什么下面的方法不起作用呢?4/mvc2型

作品:

// SpotlightsController.cs
public class SpotlightFormViewModel
{

    // props
    public Spotlight Spotlight { get; private set; }
    public SelectList Featured { get; private set; }
    public IDictionary<string, int> feature = new Dictionary<string, int>(){
        {"True", 1},
        {"False", 0},
    };

    // constr
    public SpotlightFormViewModel(Spotlight spotlight)
    {
        Spotlight = spotlight;
        Featured = new SelectList(feature.Keys, spotlight.Featured);
    }
}

// Edit.aspx
<div class="editor-label">
    <label for="Featured">Featured:</label>
</div>
<div class="editor-field">
    <%: Html.DropDownList("Featured", Model.Featured)%>
    <%: Html.ValidationMessage("Featured") %>
</div>

// Compiler Error Message: CS1501: No overload for method 'DropDownListFor' takes 1 arguments
// Edit.aspx
<div class="editor-label">
    <%: Html.LabelFor(model => model.Featured) %>
</div>
<div class="editor-field">
    <%: Html.DropDownListFor(model => model.Featured)%>
    <%: Html.ValidationMessageFor(model => model.Featured) %>
</div>
