Deserialize Soap Request Message from File to Object

Hi,

this is my incoming XML SOAP Request Message:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/" xmlns:han="http://schemas.datacontract.org/2004/07/ASDF_WCF"><soapenv:Header/><soapenv:Body><tem:GetDataUsingDataContract><tem:composite><han:MyParam1>5</han:MyParam1></tem:composite></tem:GetDataUsingDataContract></soapenv:Body></soapenv:Envelope>

[ServiceContract]
public interface IService1
{
	[OperationContract]
	ComplexResponse1 GetDataUsingDataContract(ComplexParams1 composite);
}

[DataContract]
public class ComplexParams1
{
	[DataMember]
	public int MyParam1 { get; set; }
}

Calling the service works fine.

Now i saved the incoming Request SOAP XML to a file.
I want to be able to process it again later.

How can i Deserialize the Soap Message into ComplexParams1?

i tryed already, but couldn't get to work :

Message m = Message.CreateMessage(XmlReader.Create("C:\\testSvc\\login.xml"), int.MaxValue, MessageVersion.Soap11);
SoapReflectionImporter importer = new SoapReflectionImporter(new SoapAttributeOverrides(), "urn:PlotiIntf-IPloti");
XmlTypeMapping mapp = importer.ImportTypeMapping(typeof(ComplexParams1));
XmlSerializer xmlSerializer = new XmlSerializer(mapp); //typeof(T), xr
var o = (ComplexParams1)xmlSerializer.Deserialize(m.GetReaderAtBodyContents());

i'd prefer a generic solution like the one above, so its not too verbose.
I'd like to deserialize the original XML.

Thanks for help!
