Access session variable from MVC razor view gives variable type instead of value

Question

I am trying to access a session variable inside a MVC razor view, the session variable is of type User which has a property UserID, the code is like the following:

<h3>@((User)Session["LoggedOnUser"]).UserID</h3>

It only prints the fully qualified type of the property instead of its value. I also tried the following:

@{User loginUser = (User)Session["LoggedOnUser"];}
<h3>@loginUser.UserID</h3>

It works this time. Can anyone tell me what's the difference of these two and why the first one does not work?

Thanks.

Could you share how you applied session on the specific User domain? do i simply add session declaration in the User controller and that is that? — Nurul

This is because of where you placed your close bracket for the Response.Write (@) code block. You are calling Response.Write on the User object and not the UserID property. I believe calling Response.Write on the user ojbect will just use the ToString() method and return the fully qualified type name.

The following would have worked:

@((User)Session["LoggedOnUser"].UserID)

Notice the close bracket is after the property, not after the return value from the session dictionary.

That makes sense. I changed it as following and it works: @(((User)Session["LoggedOnUser"]).UserID)
