Question

In my C# application, I want to get my MAC address by using NetworkInterface class as the following:

NetworkInterface nic in NetworkInterface.Ge         


        

Answer 1

Where you want to show that, you have to do this:

txtMac.text=getFormatMac(GetMacAddress());
public string GetMacAddress()

{
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    String sMacAddress = string.Empty;
    foreach (NetworkInterface adapter in nics)
    {
         if (sMacAddress == String.Empty)// solo retorna la mac de la primera tarjeta
         {
              IPInterfaceProperties properties = adapter.GetIPProperties();
              sMacAddress = adapter.GetPhysicalAddress().ToString();
          }
    }
    return sMacAddress;
}

public string getFormatMac(string sMacAddress)
{
    string MACwithColons = "";
    for (int i = 0; i < macName.Length; i++)
    {
        MACwithColons = MACwithColons + macName.Substring(i, 2) + ":";
        i++;
    }
    MACwithColons = MACwithColons.Substring(0, MACwithColons.Length - 1);

    return MACwithColons;
}
