WMI代码如下（可以获取所有网卡的MAC地址）：
using System;
using System.Management;
using System.Windows.Forms;namespace WMISample
{
    public class MyWMIQuery
    {
        public static void Main()
        {
            try
            {
                ManagementObjectSearcher searcher =
                    new ManagementObjectSearcher("root\\CIMV2",
                    "SELECT * FROM Win32_NetworkAdapter");                 foreach (ManagementObject queryObj in searcher.Get())
                {
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("Win32_NetworkAdapter instance");
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("MACAddress: {0}", queryObj["MACAddress"]);
                }
            }
            catch (ManagementException e)
            {
                MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
            }
        }
    }
}

chenli133() 不是，如果用户更改过mac，程序得到的会是用户更改的MAC,，我就是想得到网卡的实际物理地址，而不是用户在注册表更改后的。

leo2003知道我们可以取什么硬件信息而且用户改不了的不？

不可能吧，注册表里改过了的话，你要取到的话除非绕过了操作系统，也就是说你的代码要能直接访问硬件设备，就算驱动程序也是基于操作系统的。如果人人都能那么做还要os干吗？
或许可能，但绝不在普通人能力范围之内。lz还是放弃吧

请问获取远程机器的mac地址。。有人搞过没有啊

这个问题是不是进牛角尖里了？用户会改mac地址，你不给他管理员权限即可解决！
还有你可以设法取硬盘序列号，那也是唯一的。
远程获得mac地址，如果不过路由，那个代码这里有了。过了路由后，你查到的就是路由的mac了。这个那个我就不知道了

using System.Management;

string stringMAC = "";
string stringIP = "";
ManagementClass MC = new ManagementClass "Win32_NetworkAdapterConfiguration");
ManagementObjectCollection MOC= MC.GetInstances();
foreach(ManagementObject MO in MOC)
{
if ((bool)MO["IPEnabled"] == true)
{
stringMAC += MO["MACAddress"].ToString();
TextMAC.Text = stringMAC.ToString();
string[] IPAddresses = (string[]) MO["IPAddress"];
if(IPAddresses.Length > 0)
stringIP = IPAddresses[0];
TextIP.Text = stringIP.ToString();
}
}

引用你的话：这个问题是不是进牛角尖里了？用户会改mac地址，你不给他管理员权限即可解决！
真可笑，我的程序放在网上别人下载使用了，我还能不给他管理员权限啊?计算机是人家的，人家说的算。

MAC地址+CPU试试看，我的机子就是取不到，其他地方的都可以，所以楼主权衡使用

我这边试了一下，改过之后取到的还是真正的MAC地址啊。代码如下：
System.IO.StreamWriter writer = new System.IO.StreamWriter(FileUtil.AppDir + "\\Network.txt", false);
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
    foreach (PropertyData property in mo.Properties)
    {
        writer.WriteLine("{0} = {1};", property.Name, property.Value);
#if DEBUG
        Console.WriteLine("{0} = {1};", property.Name, property.Value);
#endif
    }
    if ((bool)mo["IPEnabled"] == true)
        _macAddress = mo["MacAddress"].ToString();
    if (!String.IsNullOrEmpty(_macAddress))
        break;
    mo.Dispose();
}
writer.Close();
moc.Dispose();

这里有。

获取远程电脑的真实MAC地址是防止用户随意更改。
