C#

here is my sample code

webservice code

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(Name = "TestService", ConformsTo = WsiProfiles.BasicProfile1_1)]
public class WebService : System.Web.Services.WebService {
// Add a member variable of the type deriving from SoapHeader.
public MyHeader timeStamp;

// Apply a SoapHeader attribute.
[WebMethod(Description = "A method that requires authentication")]
[SoapDocumentMethod(Binding = "TestService")]
[SoapHeader("timeStamp", Direction = SoapHeaderDirection.In)]
public string HelloWorld()
{
if (timeStamp == null)
timeStamp = new MyHeader();
timeStamp.MustUnderstand = true;
timeStamp.Expires = 60000;
timeStamp.Created = DateTime.UtcNow;

return "Hello World";
}


}


here is the client code

localhost.MyHeader header = new localhost.MyHeader();

// Populate the values of the SOAP header.
header.Expires = 60000;
header.Created = DateTime.UtcNow;

// Create a new instance of the proxy class.
localhost.WebService proxy = new localhost.WebService();

// Add the MyHeader SOAP header to the SOAP request.
proxy.MyHeaderValue = header;

// Call the method on the proxy class that communicates
// with your XML Web service method.
string results = proxy.HelloWorld();
i am getting result as "Hello World"
But i want it in format as
?xml version="1.0" encoding="utf-8"?>
