Sending XML over a Socket connection

[Priya Prk]

Dear all, Im very new in this, hope to get some tips. I have to send some data in XML over a Socket connection to a application that opens a TCP/IP port and acts as a server. I found some samples on google like this one : http://www.java2s.com/Tutorial/CSharp/0580\_\_Network/SimpleTcpClientsenddatatotheserver.htm But what is the best way to achieve this? Thanks in advance.

Find below code for the same.

XDocument doc = XDocument.Parse("<Hello>World</Hello>", LoadOptions.PreserveWhitespace);
string host = "localhost";
int port = 1234;

	// Look up the address for the specified host.
	IPHostEntry address = Dns.GetHostEntry(host);
	IPEndPoint ipe = new IPEndPoint(address.AddressList\[0\], port);

	// Create Socket.	
	using (Socket sock = new Socket(ipe.AddressFamily, SocketType.Stream, ProtocolType.Tcp))
	{
		sock.Connect(ipe); // Connect to the Socket.
		// Create Stream.
		using (NetworkStream sockStream = new NetworkStream(sock))
		{
			// Read from the XDocument.
			using (XmlReader reader = doc.CreateReader())
			{
				// Copy nodes to an XmlWriter which transforms them to bytes that are written to the Stream for the Socket.
				XmlWriterSettings settings = new XmlWriterSettings();
				settings.Encoding = new UTF8Encoding(false, true);
				using (XmlWriter writer = XmlWriter.Create(sockStream, settings))
				{
					while (reader.Read()) // While there is another XML node...
					{
						writer.WriteNode(reader, false); // Copy that node.
					}
				}
			}
		}
	}
