ASP.NET : sending a soap request in a HTTP post request to a webservice

I have a webservice that exposes a function called ADD(int a, int b)

and i am trying to send a request to it without adding a wsdl/reference and then calling the function, In other words, i want to explicitly send a request t开发者_开发知识库o the webservice address.

so if i send a POST request with a well-formatted-soap XML envelope as the message, would that work?

Enable ASP.NET ASMX web service for HTTP POST / GET requests
