Send XML via HTTP Post to IP:Port

Question

Ok so to start off, I'm not using any sort of web service. Right now I don't know a whole lot about the application receiving the XML other than it receives it. Big help there I know. I didn't write the receiving application but my company doesn't have any useful ways of testing the XML transmission phase.

I basically want to send an XML document like this...

<H2HXmlRequest class="myClass">
<Call>
    <CallerID></CallerID>
    <Duration>0</Duration>
</Call>
<Terminal>
    <CancelDate></CancelDate>
    <ClerkLoginTime></ClerkLoginTime>
</Terminal>
<Transaction>
    <AcceptedCurrency></AcceptedCurrency>
    <AccountId>6208700003</AccountId>
</Transaction>
</H2HXmlRequest>

...to the application that I don't really know a whole lot about. It's nothing fancy and with the proper help I could probably find out more info. But what I am looking to do is to come up with some kind of C# Forms app that can take that request above, send it on over using an IP and port, and hopefully see something happen.

Answer 1

The recommended way to make simple web requests is to use the WebClient object.

Here's a code snippet:

// assume your XML string is returned from GetXmlString()
string xml = GetXmlString();


// assume port 8080
string url = new UriBuilder("http","www.example.com",8080).ToString();     


// create a client object
using(System.Net.WebClient client = new System.Net.WebClient()) {
    // performs an HTTP POST
    client.UploadString(url, xml);  

}

If you have an IP and port why you are not trying XML over TCP/IP. In C# you can do this by using System.Net.Sockets class TCPClient. This class is having methods Connect , send and receive, in order to connect with IP and port then send message and wait to receive message.
