将简单列表与@ html.DropDownList一起使用

Question

我一直在试图弄清楚如何正确使用语法，以便在MVC中加载带有简单字符串列表的下拉列表。

什么是正确的格式？

以下代码

@Html.DropDownList("VMO", List<string>(ViewBag.VMOList), new { @class = "form-control SearchCriteria", id = "VMO", name = "VMO", multiple = "multiple"})

给我错误

"Non-invocable member 'List<T> cannot be used like a method.

如果要使用Select List和list of string来制作@Html.DropDownList()，则应如下所示：

@Html.DropDownList("VMO", new SelectlIst(ViewBag.VMOList),"Select Item", new { @class = "form-control SearchCriteria", id = "VMO", name = "VMO", multiple = "multiple"})

或者如果您想使用Select List和list of object来制作@Html.DropDownList()，则应该如下：

@Html.DropDownList("VMO", new SelectlIst(ViewBag.VMOList,"ObjectId","ObjectName"),"Select Item", new { @class = "form-control SearchCriteria", id = "VMO", name = "VMO", multiple = "multiple"})
