Hi,

 

I have developed a C# application like this.

 

public static void Main()

{

UdpClient sock = new UdpClient();

      IPEndPoint iep = new IPEndPoint(IPAddress.Parse("10.201.234.112"), 32773);

      int discarded;

      byte[] data = "" style="color:teal">HexEncoding.GetBytes("000300250000feca676574766f642e636f6de7424d5f3136313100000e10001505424d5f313631315f776974685f747261696c6f7200000edf090edc055468657265206172652074776f20726561736f6e7320666f722069742e20536865206c656674204d756d62616920616e642053616c6d616e204b68616e2077697468207468652070726f6d6973652074686174206865722062697274686461792074686973207965617220776f756c642073747269636c747920626520612066616d696c79206166666169722e204120667269656e64206f6620746865206269727468646179206769726c20736169642c20537570706f736520736865206d61646520616e20657863657074696f6e206a757374206265636175736520627564647920416b736861792077617320696e204c6f6e64", out discarded);

      sock.Send(data, data.Length, iep);

}

 

When I send packets this way, I am getting an exception when I sniff through Wireshark.

 

 

Kindly let me know what might have gone wrong?

 

Regards,

Darshan
