如何解释Wireshark的消息，并用C＃

Question

送他们我有一个巴投影机，我想远程控制自己。

巴有自己tool要做到这一点，但完全用Java编写的。

当我赶数据被发送到SWITH到HDMI信号源使用Wireshark我得到如下：

0000 00 0d 0a 01 2a bc d8 d3 85 95 91 57 08 00 45 00 ....*......W..E.

0030 01 00 14 65 00 00        ...e.. 

并切换回DVI，我得到：

0000 00 0d 0a 01 2a bc d8 d3 85 95 91 57 08 00 45 00 ....*......W..E.

我试着一些事情在C＃中，但很少成功：

IPAddress beamerIP = new IPAddress(IpToBin("!!Beamer IP!!")); 
IPEndPoint ip = new IPEndPoint(beamerIP, 1025); 
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); 

socket.Connect(ip); 
Console.WriteLine("Socket connected to " + socket.RemoteEndPoint.ToString()); 

byte[] msg = Encoding.ASCII.GetBytes(":IDVI 1 ."); 
byte[] dvi = new byte[] { 0x3a, 0x49, 0x44, 0x56, 0x49, 0x20, 0x31, 0x20, 0x0d }; 
byte[] hdmi = new byte[] { 0x3a, 0x49, 0x48, 0x44, 0x4d, 0x20, 0x31, 0x20, 0x0d }; 

int bytesSent = socket.Send(dvi); 
Console.WriteLine("Sent {0} bytes.", bytesSent); 

socket.Shutdown(SocketShutdown.Both); 
socket.Close(); 

我也试着用PCAP.NET发送像在th是thread，但收效甚微。

我做得不对或有另一种方法呢？

原来我几乎在那里。这是为我工作的代码：

// Data buffer for incoming data. 
byte[] bytes = new byte[1024]; 
// Establish the remote endpoint for the socket. 
IPAddress beamerIP = new IPAddress(IpToBin("!!Beamer IP!!")); 
IPEndPoint ip = new IPEndPoint(beamerIP, 1025); 
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); 
socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true); 
socket.Connect(ip); 
// Send the data through the socket. 
int bytesSent = socket.Send(message); //message => DVI = Encoding.ASCII.GetBytes(":IDVI 1 \r") || HDMI = Encoding.ASCII.GetBytes(":IHDM 1 \r") 
// Receive the response from the remote device. 
int bytesRec = socket.Receive(bytes); 
// Release the socket. 
socket.Shutdown(SocketShutdown.Both); 
socket.Close();
