在ASP.NET MVC的_LayoutPartial中检索会话的变量值

Question

I'm filling values to a session's like following to retrive those in _LayoutPartial view

if (userdata != null)
{
    Session["userdata"] = new SampleViewModel { FirstName = userdata.UserFirstName, LastName = userdata.UserLastName };
    FormsAuthentication.SetAuthCookie(loginmodel.UserName, false);
    return RedirectToAction("Dashboard", "Home", new { username = loginmodel.UserName });
}

I want to retrive those values in _LayoutPartial View , So I tried somethin like following

<a class="sa">
    (@Session["userdata"] as ProjectName.Models.SampleViewModel).FirstName 
    (@Session["userdata"] as ProjectName.Models.SampleViewModel).LastName
</a>

But this is not retrieving data properly . In this _LoginPartial I'm not Referencing any model also

You have your parenthesis in the wrong spot, and you need a double set - one for the casting (inner set) and one for the razor execution (outer set). It needs to be

@((Session["userdata"] as ProjectName.Models.SampleViewModel).Name)
