using System.Management;

    protected void btn_Click(object sender, EventArgs e)
    {
        ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
        ManagementObjectCollection objMOC = objMC.GetInstances();

        foreach (ManagementObject objMO in objMOC)
        {
            if (!(bool)objMO["ipEnabled"])
                continue;
           Response.Write((string)objMO["MACAddress"]);
         }
    }

除了以上程式外，還要記得加入參考System.Management
它是新增專案時不會有的，要自己加入的唷！
