如何選擇下拉列表中的HtmlHelper

Question

選項我有一個這樣的枚舉。

public enum WeekDay 
{ 
    Monday, 
    Tuesday, 
    Wednesday, 
    Thursday, 
    Friday, 
    Saturday, 
    Sunday 
} 

而且我用它在此的HtmlHelper

@Html.DropDownListFor(model => model.Day, 
    new SelectList(Enum.GetValues(typeof(WeekDay))), 
    "Select day", 
    new { @class = "form-control" }) 

我怎樣才能讓下拉列表中選擇那些日子之一，而不是顯示出「選擇日」？

@Html.DropDownListFor(model => model.Day, new 
SelectList(Enum.GetValues(typeof(WeekDay))), null, new { @class = "form-control" }) 

這將導致選擇清單中的第一項。在這種情況下Monday
