Creating a SOAP Envelope programatically and including it in the HttpWebRequest in .NET

Question

Hi all,

I'm involved in a project that would call a webservice dynamically.

I have figured out a way to call a webservice method that has no method parameters on it, but now what I need is for me to call web methods that have parameters on it.

Was wondering if there are good examples on how I could create a soap envelope and how I could include this in my HttpWebRequest?

Thank you so much!

Cheers, Ann

Answer 1

Is there any reason you want to generate SOAP envelopes manually and use HttpWebRequest to call a web service when you could generate a client proxy from the WSDL (using svcutil.exe or wsdl.exe) and let the framework do the heavy lifting for you?

Normally web services expose a contract that describes the operations you can invoke and the types that are involved allowing clients to discover it and use it.

Answer 2

What about serialization with SoapFormatter?

SoapFormatter Class

You can also use strong typed classes by using interfaces and dynamicaly loaded assemblies via

Assembly a = Assembly.LoadFile("Path");

and you'll be able to "hot plug" new proxies or other types.
