Send XML via HTTP Post to IP:Port

问题:

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.

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.
