推荐答案

如果您的意思是MAC地址，那么：

If you mean MAC address, then:

/// <summary>
/// Gets the MAC address of the current PC.
/// </summary>
/// <returns></returns>
public static PhysicalAddress GetMacAddress()
    {
    foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
        {
        // Only consider Ethernet network interfaces
        if (nic.NetworkInterfaceType == NetworkInterfaceType.Ethernet &&
            nic.OperationalStatus == OperationalStatus.Up)
            {
            return nic.GetPhysicalAddress();
            }
        }
    return null;
    }

然后你可以使用ToString来显示地址：

You can then just use ToString to display the address:

MessageBox.Show(GetMacAddress().ToString());

我在那里添加了一些调整，并对OriginalGriff充满了敬意。这将确保：

1.当前连接的适配器被选中;

2.即使是已连接，也不会考虑所有虚拟和伪适配器。

3.确保没有附加Null或空MAC。

I added a little tweak in there with all due respect to OriginalGriff. This will ensure that:
1. The Adapter that is currently connected is Picked;
2. All Virtual and Pseudo Adapters will not be considered even though the are "Connected".
3. Ensure that No Null or Empty MAC is Appended.

string mac = "";
foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
            {

                if (nic.OperationalStatus == OperationalStatus.Up && (!nic.Description.Contains("Virtual") && !nic.Description.Contains("Pseudo")))
                {
                    if (nic.GetPhysicalAddress().ToString() != "")
                    {
                        mac = nic.GetPhysicalAddress().ToString();
                    }
                }
            }
MessageBox.Show(mac);

来自系统。网名称空间：

From System.Net namespace:

public string GetMACAddress()
{
    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();
            sMacAddress = adapter.GetPhysicalAddress().ToString();
        }
    } return sMacAddress;
}
