public static void DoSomething()
{
int a;
string b;

//..do something
}

In the example above, i have declared two variables. Do they become static

    You can have "static" session-based variables within ASP.NET using System.Web.HttpContext.Current.Session.

    Example:

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Web.UI;
    using System.Web.UI.WebControls;
    
    
    namespace SomeNameSpace
    {
        public static class CSession
        {
            private static readonly string zE = "";
            private static readonly string CrLF = Environment.NewLine;
    
    
            /// 
            /// 
            /// 
            public static bool HasSession { get { return HttpContext.Current != null && HttpContext.Current.Session != null; } }
    
    
            /// 
            /// Get a session variable
            /// 
            /// 
            /// 
            public static object Get(string pSessionKey)
            {
                object t = null;
                try
                {
                    if (HasSession && HttpContext.Current.Session[pSessionKey] != null) { t = (object)HttpContext.Current.Session[pSessionKey]; }
    
                }
                catch (Exception ex) { t = null; string m = ex.Message; }
                return t;
            }//object Get(string pSessionKey)
    
    
    
            /// 
            /// Set a session variable
            /// 
            /// 
            /// 
            public static void Set(string pSessKey, object pObject)
            {
                if(!HasSession) { return; }
                HttpContext.Current.Session.Remove(pSessKey);
                HttpContext.Current.Session.Add(pSessKey, pObject);
            }//void Set(string pSessionKey, object pObject)
    
    
            public static string GetString(string pSessKey)
            {
                string sTemp = zE;
                object t = Get(pSessKey);
                if (t != null) { sTemp = (string)t; } else { sTemp = zE; }
                return sTemp;
            }//string GetString(string pSessionKey)
    
    
            public static int GetInt(string pSessKey)
            {
                int s = 0;
                object t = Get(pSessKey);
                if (t != null) { s = (int)t; }
                return s;
            }//int GetInt(string pSessionKey)
    
    
            public static Int32 GetInt32(string pSessKey)
            {
                Int32 s = 0;
                object t = Get(pSessKey);
                if (t != null) { s = (Int32)t; }
                return s;
            }//Int32 GetInt32(string pSessionKey)
    
    
            public static bool GetBool(string pSessKey)
            {
                bool s = false;
                object t = Get(pSessKey);
                if (t != null) { s = (bool)t; }
                return s;
            }//bool GetBool(string pSessionKey)
    
        }//public static class CSession
    
    }
