请教怎么获取客户端网卡的物理地址
小弟有一个小程序要获取客户端网卡的物理地址
我在网上找了一个代码。。只能获取同一个网段网卡的物理地址
其他网段的获取不了，只能显示：00-00-00-00-00
=========================================================================
请教怎么获取不同网段的网卡的物理地址！

谢谢大家了！

以前找的一点代码,不知道有没有用:

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);
}
}
}
}
