Loop through a session Object

New to this...
asp.net, C# 4.0

I am trying to loop through an object that I have put into a session for debugging display purposes.


I used this...

        // set the user into a session either loggedin or current
        public static void SetUserInfo(UserInfo User, bool LoggedIn)
        {
            string uType = _currentUser;
            if (LoggedIn){ uType = _loggedInUser;}

            if (HttpContext.Current.Session[uType] != null)
                HttpContext.Current.Session[uType] = User;
            else
                HttpContext.Current.Session.Add(uType, User);
        }

        //return the current UserInfo
        public static UserInfo GetCurrentUser(bool LoggedIn)
        {
            string uType = _currentUser;
            if (LoggedIn) { uType = _loggedInUser; }

            return HttpContext.Current.Session[uType] as UserInfo;
        }


Now this is where I am stuck...

                StringBuilder _sb = new StringBuilder();

                _sb.Append("<hr>");
                _sb.Append("<b>Current Session Count</b>");
                _sb.Append("<hr>");
                _sb.Append("Session Count: ");
                _sb.Append(HttpContext.Current.Session.Count.ToString());
                _sb.Append("<hr>");
                _sb.Append("Logged In User: ");
                UserInfo u = UserInfoManager.GetCurrentUser(true);
                _sb.Append("Name: ");
                _sb.Append( u.UserName.ToString() );
                _sb.Append("<br>");

                //need to loop here

                _res = _sb.ToString();


I want to display each item...what is a better way?

thanks tons
