        static string InnerGetQuote(string stock)
        {
            string url = @"http://www.webservicex.net/stockquote.asmx/GetQuote?symbol={0}";
            var request = HttpWebRequest.Create(string.Format(url, stock));

            using (var response = request.GetResponse())
            {
                using (var reader = new StreamReader(response.GetResponseStream(), Encoding.ASCII))
                {
                    return reader.ReadToEnd();
                }
            }


        }
    }
}

I am getting an squiggley over item;Variable 'item' is only assigned to. This code has been slightly modified from Paul Kimmel's book C# Unleashed by Sams.

Your array needs to be of the type of your stock quote. Your stock quote is an anonymous type, so we need to define the array anonymously as well. This can be done cleanly as:

    var quotes = new[]{  new { Stock = "DELL", Quote = "123" },
                         new { Stock = "MSFT", Quote = "123" },
                         new { Stock = "GOOG", Quote = "123" }};

    foreach (var item in quotes)
    {
        Console.WriteLine(item.Stock);
        Console.WriteLine(item.Quote.ToString());
    }
