MVC4列表框異常

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" }) 

這給下面的異常

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

能ayone告訴可能是什麼原因？

Answer 1

這件事做了

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