get MAC and IP of my NIC card

[sambo]

I am trying to find the IP address associated with a particular NIC card. If a PC has more than 1 NIC card, then it can have more than 1 IP address.

So... given a particular IP address, how can I find the MAC (or NIC card) associated with that IP?

Here is what I have so far... its close, but not quite there.

NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in adapters)
{
    //could have multiple MAC addresses
    lstOutput.Items.Add("MAC : " + adapter.GetPhysicalAddress());
}

lstOutput.Items.Add("Host Name : " + Dns.GetHostName());

IPAddress[] hosts = Dns.GetHostAddresses(Dns.GetHostName());
foreach (IPAddress address in hosts)
{
    //could have multiple IPs (how do I associate with the correct MAC?)
    lstOutput.Items.Add("Address : " + address.ToString());
}

Three ways to get your MAC address

[sambo]

Not sure how that article relates to my question. As you can see, I already have the MAC address. I am looking for a method to relate the MAC to the IP.

Also, that article is native c++. My code is in c# (and so is this forum).

u can get the ip and use it to get the MACAddress

public string GetMacAddress(string IPAddress) 
{ 
string strMacAddress = string.Empty ; 
try 
{ 
string strTempMacAddress= string.Empty ;
ProcessStartInfo objProcessStartInfo = new ProcessStartInfo(); 
Process objProcess = new Process(); 
objProcessStartInfo.FileName = "nbtstat"; 
objProcessStartInfo.RedirectStandardInput = false; 
objProcessStartInfo.RedirectStandardOutput = true; 
objProcessStartInfo.Arguments = "-A " + IPAddress; 
objProcessStartInfo.UseShellExecute = false; 
objProcess = Process.Start(objProcessStartInfo); 
int Counter = -1; 
while (Counter <= -1) 
{ 
Counter = strTempMacAddress.Trim().ToLower().IndexOf("mac address", 0); 
if (Counter > -1) 
{ 
break; 
} 
strTempMacAddress = objProcess.StandardOutput.ReadLine(); 
} 
objProcess.WaitForExit(); 
strMacAddress = strTempMacAddress.Trim(); 
} 
catch (Exception Ex) 
{ 
Console.WriteLine(Ex.ToString());
Console.ReadLine();
} 
return strMacAddress; 
}
