MVC @ Html.DropDownList在ViewBag得到错误使用的SelectList [英] MVC @Html.DropDownList Getting Error with SelectList in ViewBag

问题描述

我有我在控制器中创建一个列表：

I have a list which I created in the controller:

     var PayList = new[] {
      new ListEntry { Id = 1, Name = "" },
      new ListEntry { Id = 2, Name = "Yes" },  
      new ListEntry { Id = 3, Name = "No" }  

      };

     ViewBag.PayList = new SelectList(PayList, "Id", "Name");

在视图中我有以下几点：

In the view I have the following:

    @Html.DropDownList("Pay", new SelectList(ViewBag.PayList,"Id","Name")) 

当我尝试以显示它，它说以下内容：
数据绑定：System.Web.Mvc.SelectListItem'不包含名为ID的属性。不知道为什么，这是行不通的。

When I try to display it, it says the following: DataBinding: 'System.Web.Mvc.SelectListItem' does not contain a property with the name 'Id'. Not sure why this is not working.

另外我怎么默认值来选择列表中。我喜欢它默认为是。我想有办法做到从控制器做到这一点。

Also how do I default a value to the select list. I like to default it to "Yes". I thought there was a way to do do this from the controller.

推荐答案

只需使用

@Html.DropDownList("Pay", ViewBag.PayList)

在您的视图
