How do I provide information to the Web Service when the information is required as a SOAP Header?
The key here is the Web Service proxy you created using wsdl.exe or through Visual Studio .NET’s Add Web Reference menu option. If you happen to download a WSDL file for a Web Service that requires a SOAP header, .NET will create a SoapHeader class in the proxy source file. Using the previous example: public class Service1 : System.Web.Services.Protocols.SoapHttpClientProtocol { public AuthToken AuthTokenValue; [System.Xml.Serialization.XmlRootAttribute(Namespace=”http://tempuri.org/”, IsNullable=false)] public class AuthToken : SoapHeader { public string Token; }} In this case, when you create an instance of the proxy in your main application file, you’ll also create an instance of the AuthToken class and assign the string: Service1 objSvc = new Service1(); processingobjSvc.AuthTokenValue = new AuthToken(); objSvc.AuthTokenValue.
