C# 获取windows当前ip地址与mac

可以使用以下代码获取Windows当前IP地址和MAC地址：

using System.Net;
using System.Net.NetworkInformation;
using System.Linq;

public static string GetLocalIPAddress()
{
    string ipAddress = "";
    IPHostEntry host = Dns.GetHostEntry(Dns.GetHostName());
    foreach (IPAddress ip in host.AddressList)
    {
        if (ip.AddressFamily == AddressFamily.InterNetwork)
        {
            ipAddress = ip.ToString();
            break;
        }
    }
    return ipAddress;
}

public static string GetMacAddress()
{
    string macAddress = "";
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in nics)
    {
        if (adapter.OperationalStatus == OperationalStatus.Up && adapter.NetworkInterfaceType != NetworkInterfaceType.Loopback)
        {
            macAddress = string.Join(":", (from z in adapter.GetPhysicalAddress().GetAddressBytes() select z.ToString("X2")).ToArray());
            break;
        }
    }
    return macAddress;
}

上述代码中，GetLocalIPAddress()函数将返回Windows当前使用的IPv4地址，而GetMacAddress()函数将返回Windows当前使用的MAC地址。请注意，如果存在多个活动网络适配器，则GetMacAddress()函数返回的是第一个不是环回适配器的MAC地址。
