Only with "it doesn't work" is difficult to see what happens.

Have you tried with the debugger, setting a stop point and running it step by step?What kind of error are you getting?

yes the error is "Object reference not set to an instance of an object."
the session doesn't create the object

Is "Session" an array?

Session is a refrence used to create object

i don't know but it's used for security if you have a small website...the you can't access any page without login to the website or something like this...

It seems I was wrong about the brackets, have a look below. I have given you some links. I hope you can find a clue in them. Sorry not being more helpful

Maybe if you post a bit more of your code... (use the widget "improve solution").
You might be forgetting to declare something or one of the "using System.XXX" or things like that.
