var macAddr =
(from nic in NetworkInterface.GetAllNetworkInterfaces()
where nic.OperationalStatus == OperationalStatus.Up
select nic.GetPhysicalAddress().ToString()).FirstOrDefault();

From WMI:
来自 WMI：
public static string GetMACAddress1()
{
ManagementObjectSearcher objMOS = new ManagementObjectSearcher("Select * FROM Win32_NetworkAdapterConfiguration");
ManagementObjectCollection objMOC = objMOS.Get();
string macAddress = String.Empty;
foreach (ManagementObject objMO in objMOC)
{
object tempMacAddrObj = objMO["MacAddress"];
if (tempMacAddrObj == null) //Skip objects without a MACAddress
{
continue;
}
if (macAddress == String.Empty) // only return MAC Address from first card that has a MAC Address
{
macAddress = tempMacAddrObj.ToString();
}
objMO.Dispose();
}
macAddress = macAddress.Replace(":", "");
return macAddress;
}
From System.Net namespace:
从 System.Net 命名空间：
public static string GetMACAddress2()
{
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
String sMacAddress = string.Empty;
foreach (NetworkInterface adapter in nics)
{
if (sMacAddress == String.Empty)// only return MAC Address from first card
{
//IPInterfaceProperties properties = adapter.GetIPProperties(); Line is not required
sMacAddress = adapter.GetPhysicalAddress().ToString();
}
} return sMacAddress;
}

You can use WMI in C# (System.Management) to get a list of Win32_NetworkAdapter's which contains a MACAddressproperty.
您可以在 C# ( System.Management) 中使用 WMI来获取Win32_NetworkAdapter包含MACAddress属性的's列表。
