I am trying to access the session variables through this class.
But when i try ,

System.Web.SessionState.HttpSessionState s = System.Web.HttpContext.Current.Session;
System.Collections.Specialized.NameValueCollection.KeysCollection c = System.Web.HttpContext.Current.Session.Keys;
c = s.Keys;
for(int i=0;i<c.Count;i++)
{
string session_name=c.Get(i).ToString();
if(Session[session_name]==null)
{
Response.Redirect(redirect url);
return;
}
}

But i did'nt get all session variables that i have created.
Any solution.

0	Good Morning Aatish The Design and the approach we take everyday to build our System can be a Downfall. I always say let SQL be handled by the Database, Let Sessions be Handled by ASP.NET and Let low level Programming be Handled by the language C#, or VB.NET. When you are Building a web application dont access the sessions in your Classes, rather convert them to variables in C# before you can pass them to classes. In your Code above you are Accessing a session that might have got null before you use it, and this might lead to a 'Object not set for an instance of a....." Error. First thing again that i have noted in your code if(Session[session_name]==null) Session_name is not declared as a Session. Sessions are declare like this Session["session_name"] The Session name must be in quotes. Can i see how you have Declared the Session ?

Error. First thing again that i have noted in your code


if(Session[session_name]==null)

Session_name is not declared as a Session. Sessions are declare like this


Session["session_name"]

The Session name must be in quotes.

Can i see how you have Declared the Session ?
