I have to webmethod in which I want to use session variable something like this

 [WebMethod(enableSession: true)]
        public List<int> FirstMethod()
{
List<int> ListValue=getListValue();
Session["ListValue"]=ListValue;
return ListValue;
//It works fine and it also return List of integers which is ok 
}

Now I want to use this session value of "ListValue" in another method which is not working it returns me null value instead of List which was expected something like this

        [WebMethod(enableSession: true)]
                    public List<int> SecondMethod()
            {
        if(Session["ListValue"]!=null)//null value in session :(
        {List<int> ListValue=(List<int>)Session["ListValue"];
        return ListValue;
    }
    else 
    return null;
        }
}

Just a note: try to create stateless services instead of stateful. In order words: don't use session at all. – L-Four Jun 23 '14 at 11:20

@L-Three PLEASE elaborate – Jahangeer Jun 23 '14 at 11:42
Google difference between stateless and stateful. See also http://stackoverflow.com/questions/2312969/webservices-are-stateless – L-Four Jun 23 '14 at 11:54
No but I want to use that list from previous web method that is necessary in my second method so I have to use session or something.. – Jahangeer Jun 23 '14 at 12:00
That's the point: you want to AVOID that methods are dependent on each other. – L-Four Jun 23 '14 at 12:20
