How to know the structure of a SOAP package?

Question

SOAP

I connect the wsdl service to the WPF C# project.

After working out the method that sends the order, you need to know the structure of the SOAP envelope. How can this be done?

Answer 1

do you want to know what XML is sent to the server?
If yes, then you can use some HTTP debugger like Fiddler or mitmproxy.
Well, or you can use the debugger to fall into the methods and look there.
