我有一個帶有2個選擇框的表單。但是當我點擊提交按鈕時,有一個錯誤提示「無法創建抽象類」。我不知道是怎麼回事錯在這裏mvc表單無法創建抽象類

@using (Html.BeginForm("Add", "Admin")) { 
    <input type="submit" value="Add" class="btn btn-warning small-text custom-btn" /> 

    <div class="select-box"> 
     <select name="users[]" multiple size="35">@{ Html.RenderAction("UserList", "GroupsAndUsers"); }</select> 
    </div> 

    <div class="select-box"> 
     <p class="blue-text bold-text">Groups</p> 
     <select name="group" size="35">@{ Html.RenderAction("GroupList", "GroupsAndUsers"); }</select> 
    </div> 

    <input type="hidden" name="RedirectToUrl" value="~/GroupsAndUsers/AddUsers" /> 
} 

管理員/添加

[HttpPost] 
     public ActionResult Add(Array userIDs, int groupID, string RedirectToUrl) 
     { 

      return Redirect(RedirectToUrl); 
     }
