Using ViewState in c# code

Hi,

I want to access a variable through out my project.So,i am using a viewstate .
I am assigning value for a viewstate variable in this way
viewstate["username"]="xxx" in one page ,
i am not able to acess it it another page in the same project.
Is there anything i need to do to access it through out the project.

Viewstates are accesiable only on the page that u have declared It, Viewstates cannot be accessed across pages.Use Sessions to achieve u r functionality
//First Page
Sessions["username"]="xxx"

//Second Page
string strtest=Sessions["username"].ToString();

//it is not Sessions

//First Page
Session["username"]="xxx"

//Second Page
string strtest=Session["username"].ToString();

Hi
I have tried session.But,i am facing problems with session variables,when deployed in IIS.I am getting object reference not set to an object error at the statement
Session["xx"]="xxx"
if i comment out that statement it is functioning well.

This statement even working fine when i run my application using visual studio 2005.
Please help me in any other necessary code i need to code when using sessions in c#.
I have used session variables many times with vb.net code.They went well.This is the first time i am writing c# code.
