Can I consume a web service with a Socket in c# ?

I wrote a .NET/c# webservice which I then needed to consume from java server
pages.

The simplest ( and best ) solution I found, was some code to open a socket,
and send a SOAP message directly to it...constructing the SOAP message with
a class that builds the string.

Then I parse the return soap message for the result.

Now I wonder, can I do the same thing in a c# client. All I want to do is
open a Socket to the web service, send the SOAP message and retrieve the
result as a string.

Can I do this in c#:

Server = IPAddress;
Socket s = new Socket(Server, 80);
OutputStream os = socket.getOutputStream();
PrintWriter out1 = new PrintWriter(socket.getOutputStream, true);

And then send a soap message to it with:

out1.println("POST " + WebservicePath + " HTTP/1.1");
out1.println("Host: " + ServiceName);
....

and so on...

This is where I found that java code ( it's in an applet, but I converted it
to use in a jsp page ):

You can definitely use sockets to write and consume web services, but why not
to use web services support that is built into .NET and J2EE? It takes very
little code to consume or create a web service compared to using Sockets.

For a hard coded web method yes.

But for programmatic control of webservices -- not at all.

Say I want to write a generalized class for handling multiple services and
methods.

I can do that with the soap method below very effectively --- adding
parameters as vectors to the SOAP message.
 
byte [] sendArray;//put your data here
TcpClient tcpClient=new TcpClient();
tcpClient.Connect(this.ipAddress,this.portNumber);
NetworkStream networkStream=tcpClient.GetStream();
if(networkStream!=null && networkStream.CanWrite)
{
try
{
networkStream.Write(sendArray, 0,sendArray.Length);
}
....
Hope this helps.
