httpRequest, httpResponse, send GET through Stream and Receive the Result in C#

问题

This is what i'm trying to do:

• Connect to a http service

• From here, i need to get a STREAM for comunicate with that.

• Now, i send GET request, and the service answer me.

• Then, after the first GET request and the answer, i need to intercept everytime the service send me something.

How can i do?

I'm trying from yesterday with httRequest, httResponse, GetResponseStream and so on, but not working :(

How can i have the stream to "talk" with the service sending the GET request?

all this for NETCF 3.5.

Thanks a lot!

Here is a sample of how to do it synchronously

WebRequest request = WebRequest.Create(url);
request.Method = "GET";
request.ContentType = "text/html";

Stream reader = request.GetResponse().GetResponseStream();

and here an asynchronous sample

///........
WebRequest request = WebRequest.Create(url);
request.Method = "GET";
request.ContentType = "text/html";

IAsyncResult result = request.BeginGetResponse(RequestCallback, request);
///........

private void RequestCallback(IAsyncResult ar)
{
     var request = ar.AsyncState as WebRequest;
     Stream reader = request.EndGetResponse(ar).GetResponseStream();
     //use this reader to read the content
}
