C# 多网卡IP MAC 获取

网上查了不少代码，大都用两个不相关的代码来获取IP和MAC，
mc = new ManagementClass(\"Win32_NetworkAdapterConfiguration\");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
if (mo[\"IPEnabled\"].ToString() == \"True\")
{
mac = mac+mo[\"MacAddress\"].ToString()\"\\r\\n\";
}
}
