Question

I handle the loading of user data in a single static class accessed by each of my aspx pages. I would like to add functionality to support Cookies and Session into this process. However, I am finding that the Response.Cookies object and the Session object are both unavailable to my util class.

Essentially, what I have now is (in it’s own file):

namespace myProject
{    
    static class myUtil
    {
        public static myProject.User LoadUser()
        {
            //Look up user
        }
    }
}

What I would like to do is:

namespace myProject
{    
    static class myUtil
    {
        public static myProject.User LoadUser()
        {
            if (Session['user'] != null)
            { user = Session['user']; }
            else if (Response.Cookies['user'] != null)
            { user = Response.Cookies['user']; }
            else
            {               
               //Look up user
            }
        }
    }
}

How can I make this happen? In the current implementation, all references to Session and Response.Cookies are seen as undeclared objects.

For reference, here are the current imports for the class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Text.RegularExpressions;
using System.Web.UI.Page;
using System.Web.UI.WebControls;

Session in class file

using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Web;  
using System.Web.SessionState;  
/// <summary>  
/// Summary description for GetSessionHelper  
/// </summary>  
public class SessionHelper : IRequiresSessionState  
{  
    public object GetSession(string key)  
    {  
        //check session   
        if (HttpContext.Current.Session[key] != null)  
        {  
            //return session value  
            return HttpContext.Current.Session[key];  
        }  
        else  
        {  
            //return empty string  
            return string.Empty;  
        }  
    }  
}  

Cookies in class file

 if (HttpContext.Current.Request.Cookies["CodeF"] != null)
 {
    string background = HttpContext.Current.Request.Cookies["CodeF"]["BackImage"].ToString();
        }
