名称“ViewData”当前上下文中不存在

我正在开发我的第一个基于 MVC3 的应用程序，但仍然是一个新手：
我试图在母版页上成功我的 ViewData[]，因为它包含一条将在每个页面上使用的消息，但是当我尝试访问它时，它显示：

CS0103：名称“ViewData”确实在当前上下文中不存在

var msg = ViewData["msg"] as string;
        //var msg = ViewBag.msg as string;
        if (msg != null)
        {
            Response.Write (msg);
        } else if (msg == null)
        {
            Response.Write("");
        }

我不确定我是否做错了什么，或者只是无法通过我的 MasterPage 访问 ViewData[]。请帮忙！

I am working over my first application over MVC3 and still kind of a newbie in it:
I’m trying to success my ViewData[] over a master page because its contains a message that would be used over every page, but when I’m trying to access that it says:

CS0103: The name 'ViewData' does not exist in the current context

var msg = ViewData["msg"] as string;
        //var msg = ViewBag.msg as string;
        if (msg != null)
        {
            Response.Write (msg);
        } else if (msg == null)
        {
            Response.Write("");
        }

I am not sure whether I’m doing something wrong or it’s just not possible to access ViewData[] over my MasterPage. Help please!
