How to test for empty string on session object

I have the following test:

if(Session["mykey"] != string.Empty)
{...}

In VS.NET 2010's watch window, the value of Session["mykey"] is "". Yet I still go into the conditional. Do I need some other test?

--- EDIT --- After the above runs, I do reset the object by assigning string.Empty.

Of course, because you are comparing with the object of the Sessionsnot its text. Do like so:

if(Session["mykey"].ToString() != string.Empty)
{...}

other way to go is:

if(Session["mykey"] != null)
{...}
