CookieContainer in .net3.5 for windows mobile 6

Question

Hi all,

I am fairly new to programming for windows mobile and I cannot find a solution to this problem.
I am building an application which posts data to a website, the problem is that the website issues a cookie that I need to use. I found that usally CookieContainer can be used for this, but this is not available in .net3.5 for windows mobile. Does anyone know what I can use instead? There must be something that replaced CookieContainer?

any help is greatly appreciated

Many thnx in advance

(p.s. The application i am developing is in C# using visual basic 2008)

CookieContainers are not implemented in the .Net compact framework.  You will need to manage them yourself.  Here is one solution that some one wrote.

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;

namespace net.frejos.http
{
    public class CookieManager
    {
        private Dictionary cookieValues;

        public Dictionary CookieValues {
            get {
                if (this.cookieValues == null) {
                    this.cookieValues = new Dictionary();
                }

                return this.cookieValues;
            }
        }

        public void PublishCookies(HttpWebRequest webRequest)
        {
            StringBuilder sb = new StringBuilder();
            sb.Append("Cookie: ");
            foreach (string key in this.CookieValues.Keys) {
                sb.Append(key);
                sb.Append("=");
                sb.Append(this.CookieValues[key]);
                sb.Append("; ");
                sb.Append("$Path=\"/\"; ");               
            }

            webRequest.Headers.Add(sb.ToString());
            sb = null;
            webRequest = null;
        }

        public void StoreCookies(HttpWebResponse webResponse)
        {
            for (int x=0; x < webResponse.Headers.Count; x++) {
                if (webResponse.Headers.Keys[x].ToLower().Equals("set-cookie")) {
                    this.AddRawCookie( webResponse.Headers[x] );
                }
            }

            webResponse = null;
        }

        private void AddRawCookie(string rawCookieData)
        {
            string key = null;
            string value = null;

            string[] entries = null;

            if (rawCookieData.IndexOf(",") > 0)
            {
                entries = rawCookieData.Split(',');
            }
            else { 
                entries = new string[] { rawCookieData };
            }

            foreach (string entry in entries) {
                string cookieData = entry.Trim();

                if (cookieData.IndexOf(';') > 0)
                {
                    string[] temp = cookieData.Split(';');
                    cookieData = temp[0];
                }

                int index = cookieData.IndexOf('=');
                if (index > 0)
                {
                    key = cookieData.Substring(0, index);
                    value = cookieData.Substring(index + 1);
                }

                if (key != null && value != null)
                {
                    this.CookieValues[key] = value;
                }

                cookieData = null;
            }

            rawCookieData = null;
            entries = null;
            key = null;
            value = null;
        }

        public override string ToString()
        {
            StringBuilder sb = new StringBuilder();
            sb.Append("[");
            foreach (string key in this.CookieValues.Keys) {
                sb.Append("{");
                sb.Append(key);
                sb.Append(",");
                sb.Append(this.CookieValues[key]);
                sb.Append("}, ");
            }
            if (this.CookieValues.Keys.Count > 0)
            {
                sb.Remove(sb.Length - 2, 2);
            }
            sb.Append("]");

            return sb.ToString();
        }
    }
}

Here is a usage example:

CookieManager cookieManager = new CookieManager();
// Set a cookie value
cookieManager.CookieValues["FavoriteCookie"] = "Chocolate Chip";

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
// Publish the cookies to the request before asking for the response
cookieManager.PublishCookies(webRequest);

HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();
// Store any cookies returned from the response
cookieManager.StoreCookies(webResponse);

// Get the value of a cookie
string session = cookieManager.CookieValues["SESSIONID"];

webRequest = (HttpWebRequest)WebRequest.Create(url2);
cookieManager.PublishCookies(webRequest);

webResponse = (HttpWebResponse)webRequest.GetResponse();

It takes all the running you can do to stay in one place.If you want to get somewhere else,you must try to run at least twice as fast as that.
