Accepted answer
ManagementScope theScope = new ManagementScope("\\\\computerName\\root\\cimv2");

StringBuilder theQueryBuilder = new StringBuilder();
theQueryBuilder.Append("SELECT MACAddress FROM Win32_NetworkAdapter");
ObjectQuery theQuery = new ObjectQuery(theQueryBuilder.ToString());
ManagementObjectSearcher theSearcher = new ManagementObjectSearcher(theScope, theQuery);
ManagementObjectCollection theCollectionOfResults = theSearcher.Get();

foreach (ManagementObject theCurrentObject in theCollectionOfResults)
{
string macAdd = "MAC Address: " + theCurrentObject["MACAddress"].ToString();
MessageBox.Show(macAdd);
}
