XML File Model Mapping asp.net MVC3 ( Dynamically Map an xml file to a model class asp.net mvc3 ) - asp.net

Question

I am trying to implement a payment gateway(INTUIT payment gateway). I would like to serialize an xml to an model class and save into my database. I am using Desktop Model for intuit payment gateway, as the hosted model is a pain to get working with especially ssl certificates, so i dont want to try that.
I must mention i am able to get the response using the below mentioned code, where i am stuck at the moment is serialize the xml and save the response into the database. This xml is pulled from a folder in my xmlfiles folder located in my project.
For sample xml format, check out this one. https://ipp.developer.intuit.com/0085_QuickBooks_Windows_SDK/qbms/0060_Documentation/Sending_Requests
this is an xml file i am trying to post to url (https://merchantaccount.ptc.quickbooks.com/j/AppGateway)
<?xml version="1.0"?>
<?qbmsxml version="4.5"?>
<QBMSXML>
<SignonMsgsRq>
<SignonDesktopRq>
<ClientDateTime>2012-07-25T17:13:45</ClientDateTime>
<ApplicationLogin>abc.abc.us</ApplicationLogin>
<ConnectionTicket>TGT-1-g42FGaMfOTQ82GcWFBpsuQ</ConnectionTicket>
</SignonDesktopRq>
</SignonMsgsRq>
<QBMSXMLMsgsRq>
<CustomerCreditCardChargeRq>
<TransRequestID>4540453787200</TransRequestID>
<CreditCardNumber>4111111111111111</CreditCardNumber>
<ExpirationMonth>12</ExpirationMonth>
<ExpirationYear>2016</ExpirationYear>
<IsCardPresent>false</IsCardPresent>
<Amount>10.00</Amount>
</CustomerCreditCardChargeRq>
</QBMSXMLMsgsRq>
</QBMSXML>
The Controller i use to make a post to the url
public ActionResult Index()
{
WebRequest req = null;
WebResponse rsp = null;
string fileName = Server.MapPath("~/XMLData/XMLFile1.xml");
string uri = "https://merchantaccount.ptc.quickbooks.com/j/AppGateway";
req = WebRequest.Create(uri);
//req.Proxy = WebProxy.GetDefaultProxy(); // Enable if using proxy
req.Method = "POST"; // Post method
req.ContentType = "application/x-qbmsxml"; // content type
// Wrap the request stream with a text-based writer
StreamWriter writer = new StreamWriter(req.GetRequestStream());
// Write the XML text into the stream
writer.WriteLine(this.GetTextFromXMLFile(fileName));
writer.Close();
// Send the data to the webserver
rsp = req.GetResponse();
// var resp = (Object)rsp.GetResponseStream();
if (rsp != null)
{
StreamReader inStream = new StreamReader(rsp.GetResponseStream());
var data = inStream.ReadToEnd();
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(data);
string path = Server.MapPath("~/XMLData/SampleXmlE2E.xml");
xmlDoc.Save(path);//regenerates the xml file in different system.
}
return View();
//XElement root = new XElement("root");
//root.Add(new XElement("element1"));
//root.Add(new XElement("element2"));
//root.Add(new XAttribute("attribute1", "a value"));
//return new XmlResult(root);
}
private string GetTextFromXMLFile(string file)
{
StreamReader reader = new StreamReader(file);
string ret = reader.ReadToEnd();
reader.Close();
return ret;
}
private string SendRequest(Uri UriObj, string data)
{
string _result;
var request = (HttpWebRequest)WebRequest.Create(UriObj);
request.Method = "POST";
request.ContentType = "text/xml";
var writer = new StreamWriter(request.GetRequestStream());
writer.Write(data);
writer.Close();
var response = (HttpWebResponse)request.GetResponse();
var streamResponse = response.GetResponseStream();
var streamRead = new StreamReader(streamResponse);
_result = streamRead.ReadToEnd().Trim();
streamRead.Close();
streamResponse.Close();
response.Close();
return _result;
}
Any help would be appreciated. Thanks

Varun,
[Edit -update]
Based on this XML:
<?qbmsxml version="4.5"?>
<QBMSXML>
<SignonMsgsRq>
<SignonDesktopRq>
<ClientDateTime>2012-07-25T17:13:45</ClientDateTime>
<ApplicationLogin>app.app.login.url</ApplicationLogin>
<ConnectionTicket>TGT-1-g42FGaMfOTQ82GcWFBpsuQ</ConnectionTicket>
</SignonDesktopRq>
</SignonMsgsRq>
<QBMSXMLMsgsRq>
<CustomerCreditCardChargeRq>
<TransRequestID>4540453787200</TransRequestID>
<CreditCardNumber>4111111111111111</CreditCardNumber>
<ExpirationMonth>12</ExpirationMonth>
<ExpirationYear>2016</ExpirationYear>
<IsCardPresent>false</IsCardPresent>
<Amount>10.00</Amount>
</CustomerCreditCardChargeRq>
</QBMSXMLMsgsRq>
</QBMSXML>
Here's the class structure that you'd need to deserialize into as per the example above:
[XmlRoot("QBMSXML")]
public class QbmsXml
{
[XmlElement("SignonMsgsRq")]
public SignonMsgsRq SignonMsgsRq { get; set; }
[XmlElement("QBMSXMLMsgsRq")]
public QbmsXmlMsgsRq QbmsXmlMsgsRq { get; set; }
}
public class SignonMsgsRq
{
[XmlElement("SignonDesktopRq")]
public SignonDesktopRq SignonDesktopRq { get; set; }
}
public class SignonDesktopRq
{
[XmlElement("ClientDateTime")]
public DateTime ClientDateTime { get; set; }
[XmlElement("ApplicationLogin")]
public string ApplicationLogin { get; set; }
[XmlElement("ConnectionTicket")]
public string ConnectionTicket { get; set; }
}
public class QbmsXmlMsgsRq
{
[XmlElement("CustomerCreditCardChargeRq")]
public CustomerCreditCardChargeRq CustomerCreditCardChargeRq { get; set; }
}
public class CustomerCreditCardChargeRq
{
[XmlElement("TransRequestID")]
public Int64 TransRequestID { get; set; }
[XmlElement("CreditCardNumber")]
public string CreditCardNumber { get; set; }
[XmlElement("ExpirationMonth")]
public int ExpirationMonth { get; set; }
[XmlElement("ExpirationYear")]
public int ExpirationYear { get; set; }
[XmlElement("IsCardPresent")]
public bool IsCardPresent { get; set; }
[XmlElement("Amount")]
public double Amount { get; set; }
}
Just use the xmlSerialiser along the lines of:
class Program
{
private static T DeSerialize<T>(string fromXmlFile) where T: class
{
if (!File.Exists(fromXmlFile))
{
return default(T);
}
T deserializedClass;
var serializer = new XmlSerializer(typeof(T));
// ToDo: add error catching etc
using (var reader = new StreamReader(fromXmlFile))
{
deserializedClass = (T)serializer.Deserialize(reader);
}
return deserializedClass;
}
static void Main(string[] args)
{
var yourXmlFilePath = #"d:\temp\xmltest.xml";
var deserializedClass = DeSerialize<QbmsXml>(yourXmlFilePath);
Console.WriteLine(deserializedClass
.QbmsXmlMsgsRq
.CustomerCreditCardChargeRq.Amount);
Console.Read();
}
}
hope this helps.
