Mujeeb => .NET

I want to add a SOAP header but the webservice is not exposing a header in the WSDL.

The problem is that I have to communicate with a Web service that I didn't author. The service doesn't expose SOAP headers in the WSDL but I know the layout and format of the header(s).

The solution I worked out is to:

1. Generate a Web service proxy

2. Create a class that describes the SOAP header you will be sending:

[XmlRoot(Namespace = "http://ech.client.nl/vendor")]
public class VENDOR : SoapHeader
{
public string Value;
}
3. Add a public member variable to the proxy class named "vendorHeader":

public VENDOR vendorHeader;

4. Modify the method you are invoking and add the following attribute to that method:

[SoapHeader("vendorHeader", Direction = SoapHeaderDirection.In)]
5. Modify the body of the method call so that you create an instance of the member variable. Put this code before the "Invoke" code:

vendorHeader = new VENDOR();
vendorHeader.Value = "username and password";


That's it.
