读取ViewData子值

Question

问：我如何获得此ViewData？ @ViewData["MyCustomCollection"]["MyParam1"]它会返回错误Cannot apply indexing with [] to an expression of type 'object'

查看（MyCustomCollecion有[UIHint("MyCustomEditor")]

@Html.EditorFor(model => model.MyCustomCollection, new
{
    MyCustomCollection = new
    {
        Param1 = "MyParam1"
        Param2 = "MyParam2"
    }
})

MyCustomEditor

(...)
<span>@ViewData["MyCustomCollection"]["MyParam1"]<span>
<span>@ViewData["MyCustomCollection"]["MyParam2"]<span>
(...)

重要提示：我需要将MyCustomCollection设为父级。我不能这样做：

@Html.EditorFor(model => model.MyCustomCollection, new
{
   Param1 = "MyParam1"
   Param2 = "MyParam2"
})
