推荐答案

您必须将SelectList实例传递给视图.您可以像这样将其添加到视图包(或视图模型)中:

You have to pass a SelectList instance to the view. You can either add it to the viewbag (or to the viewmodel) like this:

ViewBag.DropDown = new SelectList(IEnumerable of elements to be listed in the dropdown, "element field to be used as index", "element field to be used as display text")};

比您可以在自己的视图中使用它的方式:

Than you can use it in your view:

@Html.DropDownList("DropDown")

当然，请向MSDN咨询其他功能:

http://msdn.microsoft .com/en-us/library/system.web.webpages.html.htmlhelper.dropdownlist(v = vs.99).aspx [

Of course consult MSDN for other features:
