It is a best practice not to create the SelectList in the view. You should create it in the controller and pass it using the ViewData.
最好不要在视图中创建 SelectList。您应该在控制器中创建它并使用 ViewData 传递它。
Example:
例子：
var list = new SelectList(new []
{
new { ID = "1", Name = "name1" },
new { ID = "2", Name = "name2" },
new { ID = "3", Name = "name3" },
},
"ID", "Name", 1);
ViewData["list"]=list;
return View();
you pass to the constratctor: the IEnumerable objec,the value field the text field and the selected value.
您传递给构造函数：IEnumerable 对象、值字段、文本字段和所选值。
in the View:
在视图中：
<%=Html.DropDownList("list",ViewData["list"] as SelectList) %>

Code below assumes you are using razor view engine if not you will need to convert it.
下面的代码假设您使用的是剃刀视图引擎，否则您将需要转换它。
@{
var listItems = new List<ListItem>();
listItems.Add(new ListItem{Text="Yes", Value="1"});
listItems.Add(new ListItem{Text="No", Value="0"});
}
@Html.DropDownListFor(m=>m.SelectedValue, listItem);
You should consider creating the model in your code instead of the view. Also this would be a good candidate for an editor template.
您应该考虑在代码而不是视图中创建模型。这也是编辑器模板的一个很好的候选者。

如果你想明确一点，那就试试
@{
var domainsList = new SelectList(new []
{
new SelectListItem { Text = ".Com", Value = ".com", Selected = true },
new SelectListItem { Text = ".Shopping", Value = ".shopping"},
new SelectListItem { Text = ".Org", Value = ".org"},
new SelectListItem { Text = ".Net", Value = ".net"},
new SelectListItem { Text = ".AE", Value = ".ae"},
new SelectListItem { Text = ".Info", Value = ".info"},
}, "Value", "Text");
}
@Html.DropDownList("TopLevelDomains", domainsList)

This solved it for me:
这为我解决了：
<td>
@{ var RlistItems = new List<SelectListItem>();
RlistItems.Add(new SelectListItem { Text = "Select Room Type", Value = "0" });
RlistItems.Add(new SelectListItem { Text = "Meeting Room", Value = "1" });
RlistItems.Add(new SelectListItem { Text = "Office", Value = "2" });
RlistItems.Add(new SelectListItem { Text = "Cafeteria", Value = "3" });
}
@Html.DropDownListFor(model=>model.FirstOrDefault().RoomType
,RlistItems,RlistItems[item.RoomType.Value].Selected=true )
