how to serialize an object in soap format and add prefixes - soap

Question

I have an object and iam serilaizing the object using xml seriliazer.
after serilaizing my data looks like this
<?xml version="1.0" encoding="utf-8"?>
<doPaymentRequest xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Credentials>
<accountId>101</accountId>
<userName>santosh#gmail.com</userName>
<password>1234</password>
</Credentials>
<custFirstName>santosh</custFirstName>
<custLastName>reddy</custLastName>
<ssn>1234</ssn>
<phoneNbr>1234567890</phoneNbr>
<PaymentRequest>
<ncpTranCode>10104587</ncpTranCode>
<tranType>PAY</tranType>
<Payment>
<tranAmount>100</tranAmount>
<paymentDateDate>2013-04-30</paymentDateDate>
<tenderType>C</tenderType>
</Payment>
</PaymentRequest>
<csoId>203</csoId>
<csoStCode>8974</csoStCode>
</doPaymentRequest>
But my xml should look like this way
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:req="http://xxxxxxxxxxxx" xmlns:com="http://xxxxxxxxxxxxxxxxxx">
<soapenv:Header/>
<soapenv:Body>
<req:doPaymentRequest>
<req:credentials>
<com:accountId>*********</com:accountId>
<com:userName>*********</com:userName>
<com:password>*********</com:password>
</req:credentials>
<req:custFirstName>Test</req:custFirstName>
<!-- Optional: -->
<req:custMiddleName>Test</req:custMiddleName>
<req:custLastName>Test</req:custLastName>
<req:ssn>7895</req:ssn>
<!-- Optional: -->
<req:phoneNbr>1234567890</req:phoneNbr>
<req:paymentRequest>
<req:ncpTranCode>10104587</req:ncpTranCode>
<req:tranType>PAY</req:tranType>
<req:payment>
<req:tranAmount>100</req:tranAmount>
<req:paymentDateDate>2013-04-30</req:paymentDateDate>
<req:tenderType>C</req:tenderType>
</req:payment>
</req:paymentRequest>
<req:csoId>203</req:csoId>
<req:csoStCode>8974</req:csoStCode>
</req:doPaymentRequest>
</soapenv:Body>
</soapenv:Envelope>
How to add prefixes like req,com.
I am using XmlSerializer to convert my object to xml.
xmlSerializer.Serialize(stWriter, myobject);
is there any SOAP serialize like thing
............Edited.............
I used SoapFormatter and serialized the object and converting it to string using
Encoding.ASCII.GetString(memStream.GetBuffer())
then my string looks weird like following.
<SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:clr="http://schemas.microsoft.com/soap/encoding/clr/1.0" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

Am i missing anything here...

Answer 1

[Serializable]
public class MyData
{
public int MyNumber { get; set; }
public string Name { get; set; }
}
class Program
{
static void Main(string[] args)
{
using (MemoryStream stream = new MemoryStream())
{
MyData data = new MyData() { MyNumber = 11, Name = "StackOverflow" };
XmlSerializer serializerXML = new XmlSerializer(data.GetType());
serializerXML.Serialize(stream, data);
stream.Seek(0, SeekOrigin.Begin);
data = (MyData)serializerXML.Deserialize(stream);
// We're cheating here, because I assume the SOAP data
// will be larger than the previous stream.
stream.Seek(0, SeekOrigin.Begin);
SoapFormatter serializerSoap = new SoapFormatter();
serializerSoap.Serialize(stream, data);
stream.Seek(0, SeekOrigin.Begin);
data = (MyData)serializerSoap.Deserialize(stream);
}
}
}
