推荐答案

这是不是在视图中创建选择列表的最佳实践。你应该在控制器中创建并使用ViewData的传递。

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.

例如：

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();

您传递给constratctor：了IEnumerable objec，值字段中的文本字段和选择的值

you pass to the constratctor: the IEnumerable objec,the value field the text field and the selected value.

在View：

<%=Html.DropDownList("list",ViewData["list"] as SelectList) %>
