MVC4列表框异常

Question

我想填充列表框

@Html.ListBox("Employees", new MultiSelectList((IEnumerable<CubicHRM.Data.Entities.Employee>)(ViewData["Employees"]) as SelectList, "UserID", "UserName"), new { id = "sourceItems", Multiple = "multiple" }) 

这给下面的异常

Unable to cast object of type 'System.Web.Mvc.SelectList' to type 'System.Collections.Generic.IEnumerable 

能ayone告诉可能是什么原因？

Answer 1

这件事做了

@Html.ListBox("Employees", (MultiSelectList)ViewData["Employees"], new { id = "sourceItems", Multiple = "multiple" })
