What is the best way to convert/cast a SoapUnknownHeader to a clas

[Michael]

In my ProcessMessage function inside my SoapExtension, I need to convert the
incoming SoapUnknownHeader to the original class.

Code snippet currently looks like the following:
foreach (SoapUnknownHeader header in message.Headers)
{
if (header.Element.Name.CompareTo("ScCredentials")==0)
{
ScCredentials credentials = (ScCredentials) ((SoapHeader)header);

I get an invalid cast exception with the above. Incoming XML appears to be
correct...I must be over looking something.

I thought about using the XMLSerializer...but I am thinking there should be
a light weight way of doing this.

TIA

The easiest way to do this is to tell the serializer about your custom
header at coding time.

If you search for SoapHeader on MSDN, you'll find some great examples of
creating custom header classes and then using them in your web services.
If you already have the header class created, all you have to do is tell
the web service about the header so that it will be made available to you
programatically at the time your web method is invoked.

Hope this helps,
