Send XML string through HTTP

[rrocket]

I need to send xml data to a specified server and return the results. I have it covered in classic asp, but need to upgrade to .net 2.0 (C#). If anyone has a link to a tutorial or insight I would appreciate it.

This is what I have so far, but I cannot get it to work...

string postData = this.tbSend.Text;
        string uriString = "http://website.com";
        String strXML;
 
        XMLHTTPClass xmlHTTP = new XMLHTTPClass();
 
        xmlHTTP.open("POST", uriString, false, null, null);
        xmlHTTP.send(postData);
 
        while (xmlHTTP.readyState != 4)
        {
        }
 
        strXML = (string)xmlHTTP.responseText;
        this.tbGet.Text = strXML; 

What namespace does xmlHTTPClass use? I have been checking the web for a while, but cannot come up with anything.

Does anyone have a clue on how to do this? Just to clarify further.... Values from a form will populate a XML string that is sent to DHL... Once they get the information they will also return rates to me.

Is this the right forum for this type of question or should I put it in the XML forum too?

It's MSXML2.XMLHTTPC lass, but that's not .NET.

I think you could accomplish this with XMLDocument.


I found this that seems to comapre .NET vs MSXML2

Use Remoting/WebService

Create the instance of that remote class in your code.

Using that proxy, call that method and pass your xml string.

This might help to explain what I am trying to do a bit better. This is a portion that I did with Classic ASP.

Sorry buddy, I had misunderstood

Here is the code which will do that in .NET

Yeah that's what I thought, the link I left was a conversion for it too.

Thanks guys... That was the info I needed. Not to say that I will not have more questions later, but for now I am at least able to keep on plugging. :)
