MVC Razor get option value from select with FormCollection
提问by Lord Vermillion
My view has a Select with elements(options) from my ViewModel.
我的视图有一个来自我的 ViewModel 的带有元素（选项）的选择。
@using (Html.BeginForm("NewUser", "Admin"))
{
<select multiple="" id="inputRole" class="form-control" size="6" name="inputRole">
@foreach (var item in Model.roller)
{
<option>@item.Name</option>
}
</select>
}
How can i get the selected value in my Controller?
如何在我的控制器中获取选定的值？
[HttpPost]
public ActionResult NewUser(FormCollection formCollection)
{
String roleValue1 = formCollection.Get("inputRole");
}
