推荐答案

试试这个。在我的情况下它工作正常。

Try this. In my case it is working fine.

@Html.DropDownList("SelectedEmployee",   new SelectList((System.Collections.IEnumerable)ViewData["categories"], "CategoryId", "CategoryName"))

这里CategoryId和CategoryName是您的类别模型的属性。

Here CategoryId and CategoryName is the property of your Category model.
