This attribute is used to receive a custom SoapHeader. Before you can use this attribute, you need to add a member variable of the appropriate SoapHeader type to your web service or proxy class (for example, Public ReceivedHeader As MyCustomHeader). Before invoking a method, the client will set this member to the appropriate header object. You must also add a SoapHeaderAttribute to each method that wants to process the custom header. This declaration specifies the class member that received the custom header object, as in [SoapHeader(MemberName = "ReceivedHeader"].
If a method will process more than one SoapHeader, just add multiple SoapHeaderAttribute declarations. You can also receive all headers that are not defined in the web service by creating a member array of SoapUnknownHeader objects and using it in the SoapHeaderAttribute declaration.
