Why do you need to do this? I guess, if nothing else, you could just
craft a properly formatted SOAP message and send it on over to the Web
service in an HTTP request, but why do all this heavy lifting? Proxy
classes are designed to simplify this whole process.

Hi Scott and other reader,
I have to write a program for call any webservice, this program must get
webservice's wsdl and show a xform for geting parameters and then send
parameter to webservice and show result.
How can send a SOAP message to a webservice? I wrote my program in asp.net
and C#.

Thanks for help, special scott.

So is the challenge, then, creating the form on the fly? That is, you
do not know the Web service's WSDL contract prior to when you want to
call it?

This may help you get started. A great article from Roman Kiss on
CodeProject demonstrates programmatically reading WSDL and dynamically
generating in memory a proxy class that can be used to exercise methods. I
wrote a short snippet to test it below.

The key is the ServiceDescription class, at least, it's the starting point.

---------------- WebServiceAccessor.cs starts ----------------------------
Go to Roman's excellent article on The Code Project at:
http://www.thecodeproject.com/cs/webservices/webservicecallback.asp then
look for the code snippet titled WebServiceAccessor.
---------------- WebServiceAccessor.cs ends ------------------------------

---------------- ExeWSDL.cs starts ----------------------------
using System;
using System.Diagnostics;
using System.IO;
using System.Text;
using System.Net;

namespace ExeWSDL
{
public class WSDLExecuter
{
public static void Main(string [] args)
{
WebServiceAccessor ac = new
WebServiceAccessor("http://www.mccomsoft.com/Test.asmx?wsdl");
object esObj = ac.CreateInstance("Test");
//string sProgramArguments = "";
object retval = ac.Invoke(esObj, "TestResponse", null);
Console.WriteLine((string) retval);
}
}
}
---------------- ExeWSDL.cs ends ------------------------------

Build with:

csc -out:ExeWSDL.exe ExeWSDL.cs WebServiceAccessor.cs
