How do I obtain the physical (MAC) address of an IP address using C#?

Question

From C#, I want to do the equivalent of the following:

arp -a |findstr 192.168.1.254

Alternatively, the answer could call the SendARP funct

To find your own:

Add a reference to System.Management

ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");

ManagementObjectCollection mcCol = mc.GetInstances();

foreach (ManagementObject mcObj in mcCol)
{
  Console.WriteLine(mcObj["Caption"].ToString());
  Console.WriteLine(mcObj["MacAddress"].ToString());
}

Not sure about finding that of another device.
