How to make a XML call in C#
I'm new to C# and wanted to know how to make a XML call.
I have the following XML code. I need to do a REQUEST to Authorize.NET, and am expecting a RESPONSE with an XML document.
This is what I tried, but it fails:

<?xml version="1.0" encoding="utf-8"?>
<getTransactionDetailsRequest xmlns="AnetApi/xml/v1/schema/AnetApiSchema.xsd">
<merchantAuthentication>
<name>YourUserLogin</name>
<transactionKey>YourTranKey</transactionKey>

<transId>1111111111</transId>
</getTransactionDetailsRequest>This is what I tried, but it fails:
private string GetTransactionDetails(long _transID)
{
string reason = string.Empty;
bool IsLive = false;
const string LIVE_URL = "https://api.authorize.net/xml/v1/request.api";
const string TEST_URL = "https://apitest.authorize.net/xml/v1/request.api";
const string TEST_NAME = "abc";
const string TEST_TRANS_KEY = "abc";
const string TEST_TRANS_ID = "2226934625";
XNamespace ns = "AnetApi/xml/v1/schema/AnetApiSchema.xsd";
XDocument doc = new XDocument(
new XElement(ns + "getTransactionDetailsRequest",
new XAttribute("xmlns", "AnetApi/xml/v1/schema/AnetApiSchema.xsd"),
new XElement(ns + "merchantAuthentication",
new XElement(ns + "name", TEST_NAME),
new XElement(ns + "transactionKey", TEST_TRANS_KEY)),
new XElement(ns + "transId", TEST_TRANS_ID))
);
MemoryStream stream = new MemoryStream();
doc.Save(stream);
byte[] postBytes = new byte[stream.Length];
stream.Seek(0, SeekOrigin.Begin);
stream.Read(postBytes, 0, postBytes.Length);
stream.Close();
WebClient WC = new WebClient();
ServicePointManager.ServerCertificateValidationCallback = TrustAllCertificateCallback;
HttpWebRequest wrequest = (HttpWebRequest)WebRequest.Create(IsLive ? LIVE_URL : TEST_URL);
wrequest.Timeout = 300000;
wrequest.Method = "POST";
wrequest.ContentType = "application/x-www-form-urlencoded";
wrequest.ContentLength = stream.Length;
Stream lilriver = wrequest.GetRequestStream();
lilriver.Write(postBytes, 0, postBytes.Length);
HttpWebResponse wresponse = (HttpWebResponse)wrequest.GetResponse();
Stream rstream = wresponse.GetResponseStream();
Encoding enc = System.Text.Encoding.GetEncoding("utf-8");
StreamReader strRead = new StreamReader(rstream, enc);
string result = strRead.ReadToEnd();
wresponse.Close();
strRead.Close();
rstream.Close();
return reason;
}
When you say "it fails", do you get an exception on executing this code? If so, can you share those details?

Exception: Cannot access a closed Stream.

Thanks, I resolved that by moving it down a bit, but still can't get the XML response which looks like the below:
Any help would be greatly appreciated.

If you place a break point at
what is in the webResponse object after this call completes?
WebResponse webResponse = wrequest.GetResponse();what is in the webResponse object after this call completes?
ASKER
I can't output the entirety of the webResponse object, but here is the header of it.
After: xmldoc.Load(XmlReader.Crea
The below is the value of xmldoc's InnerXML
The next line is where it seems to fall apart -- nothing is retrieved in SelectNodes.
I also tried another way (below), but node comes back as NULL:

The XML I am sending in my request has a namespace. However, the response XML I'm receiving from Authorize.NET is completely different than the request XML I am sending to them.

Thanks. It fails on the following line with the following exception:

The attached screen shot shows what xml doc looks like after the following line of code -- hoping this info would help:
XmlNodeList xmList = xmldoc.SelectNodes("s:/getTransactionDetailsResponse/s:transaction", mgr);'s:/getTransactionDetailsR
