读取ViewData子值

Question

@ViewData["MyCustomCollection"]["MyParam1"] Q:我如何得到这个ViewData? ViewData它返回错误**Cannot apply indexing with [] to an expression of type 'object'*

视图(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>
(...)

重要的是:我需要将MyCustomCollection 设置为父级。我不能这么做：

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