Answer 1

I use a similar method to dasblinkenlight's in a function to return a single key value from a Cookie containing a JSON array loaded into a Dictionary as follows:

    /// 

    /// Gets a single key Value from a Json filled cookie with 'cookiename','key' 
    /// 
    public static string GetSpecialCookieKeyVal(string _CookieName, string _key)
    {
        //CALL COOKIE VALUES INTO DICTIONARY
        Dictionary dictCookie =
        JsonConvert.DeserializeObject>
         (MyCookinator.Get(_CookieName));

        string value;
        if (dictCookie.TryGetValue( _key, out value))
        {
            return value;
        }
        else
        {
            return "0";
        }

    }

Where "MyCookinator.Get()" is another simple Cookie function getting an http cookie overall value.
