Console App Does not return XML Data when Calling an HTTP Webservice

Hi,

I've written a C# console application to call a RESTful HTTP web service per below:

class Program
    {
        static void Main(string[] args)
        {
        string URL = "https://sapiqa.overstock.com/api";
        string APIMethod = "GetOrders2";
        string MerchantKey = "OurMerchKey";
        string AuthenticationKey = "OurAuthKey";
        string GetOrders2Response;
        WebRequest wrq = WebRequest.Create("https://sapiqa.overstock.com/api?" + APIMethod + "?MerchantKey=" + MerchantKey + "?AuthenticationKey=" + AuthenticationKey);
        wrq.Method = "POST";
        // Create POST data and convert it to a byte array. Strip out unnecessary text. 
        byte[] byteArray = Encoding.UTF8.GetBytes(URL.Replace(APIMethod, ""));
        // Set the ContentType property of the WebRequest. 
        wrq.ContentType = "application/x-www-form-urlencoded";
        // Set the ContentLength property of the WebRequest. 
        wrq.ContentLength = byteArray.Length;

        Stream dataStream = wrq.GetRequestStream();
        // Write the data to the request stream. 
        dataStream.Write(byteArray, 0, byteArray.Length);
        // Close the Stream object. 
        dataStream.Close();
        // Get the response. 
        WebResponse response = wrq.GetResponse();
        // Display the status. 
        Console.WriteLine(((HttpWebResponse)response).StatusDescription);
        // Get the stream containing content returned by the server. 
        dataStream = response.GetResponseStream();
        // Open the stream using a StreamReader for easy access. 
        StreamReader reader = new StreamReader(dataStream);
        // Read the content. 
        string responseFromServer = reader.ReadToEnd();
        // Display the content. 
        GetOrders2Response = responseFromServer;
        Console.WriteLine(responseFromServer);
        
        // Clean up the streams. 
        reader.Close();
        dataStream.Close();
        response.Close();
        Console.ReadKey();
        }
    }

The solution builds without errors.  When I F5 to debug, the console window doesn't stay open and I see no confirmation that the web service was called or the response that was recieved.

How do I keep the console open?  What must be done to write the XML response to SQL Server?  Ideally, I want to use this as a script component in SSIS but want to start with the basicss first.

Thanks for your help and guidance.
