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.Token = <ACTUAL token value>;
Web Servicestring strResult =
objSvc.MyBillableWebMethod();
