Converting Java Code to C#

I have about 60 lines of Java code I need to convert to C#. This code creates a UDP packet and sends it to a destination IP address on port 1761. I'm not sure what the equivalent C# code is to manipulate the java byte data type and not sure what the Datagram equivalent is.

This is the Java code I need to translate to C#

private void jBtnReadActionPerformed(ActionEvent e)
	{
		byte buf[] = new byte[512];
		int i = 0;


		//1. Check the Buttons to verify that only UDP-API command button is selected
		if (true == jRBtnUdpCmd.isSelected())
		{
			Integer i1 = Integer.valueOf(jTxtCmdId.getText());
			int tmp = i1.intValue();
			buf[i++] = (byte)((tmp >> 8) & 0xFF);
			buf[i++] = (byte)(tmp & 0xFF);


			// set Byte 2:0x00 (read request) and byte three: 0x00 (reserved)
			buf[i++] = READ_REQUEST; // READ_REQUEST is set to 0x00
			buf[i++] = 1; // This byte is reserved.
// buf[i++] = RESERVED; // This byte is reserved.


			// convert the space delimited ASCII hex data to byte value
			String strData = jTxtCmdData.getText();
			int strDataLen = strData.length();


//System.out.println("String: " + strData + "    Len: " + strDataLen);


			byte[] newBuf = new byte[strDataLen];
			int len = convertAsciiHexToByte(strData, strDataLen, newBuf);


			// insert 4 bytes of header and copy the remaining bytes here.
			for (i=4; i < 4+len; i++)
			{
				buf[i] = newBuf[i - 4];
			}


			// Send the IP Data
			sendIpData(buf, i);
		}
	}
	

	private void sendIpData ( byte bData[], int dataLen )
	{
		if (dataLen > 0)
		{
			// Display data to send
			DisplayOutData(bData, dataLen);


			// Build packet with destination Ip address, source & destination
			// port numbers
			DatagramPacket packet = new DatagramPacket(bData, dataLen, inetAddr, iPortNum);


			try
			{
				dataSocket.send(packet);
			}
			catch (IOException ioe)
			{
				System.err.println(ioe);
			}
		}
	}

What is the C# equivalent of this code?

buf[i++] = (byte)((tmp >> 8) & 0xFF);
buf[i++] = (byte)(tmp & 0xFF);

(Shifting bits and ANDING the operation...)

This is the code I think I need in place of the Java Datagram UDP send packet code

Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, 
ProtocolType.Udp); 
 
IPAddress serverAddr = IPAddress.Parse("192.168.2.255"); 
 
IPEndPoint endPoint = new IPEndPoint(serverAddr, 11000); 
 
string text = "Hello"; 
byte[] send_buffer = Encoding.ASCII.GetBytes(text ); 
 
sock.SendTo(send_buffer , endPoint);

Any help would be appreciated to point me in thre right direction.

Thank you,

Garry

Re: Converting Java Code to C#

Microsoft provide something for conversion process. I never use this so I have no idea, but you can test this !
