网卡的MAC地址?

Question

[DllImport("Iphlpapi.dll")]
private static unsafe extern int SendARP(Int32 dest,Int32 host,ref IntPtr mac,ref IntPtr length);
[DllImport("Ws2_32.dll")]
private static extern Int32 inet_addr(string ip);Int32 ldest= inet_addr("157.60.68.163");//目的地的ip
Int32 lhost= inet_addr("157.60.68.33");//本地的iptry
{
Byte[] macinfo=new Byte[6];
Int32 length=6;IntPtr mac=new IntPtr(macinfo[0]);
IntPtr len=new IntPtr(6);
int ii=SendARP(ldest,lhost, ref mac, ref len);Console.WriteLine("Mac Add:"+mac);
Console.WriteLine("length:"+len);
}
catch(Exception err)
{
Console.WriteLine(err);
}

Answer 1

可以使用WMI来得到多个网卡的MAC地址. 代码参考如下:/// <summary> 
      /// 得到网卡物理地址 
      /// </summary> 
      /// <returns>网卡物理地址列表</returns> 
      public string[] GetMacAddress() 
      { 
         ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); 
         ManagementObjectCollection moc = mc.GetInstances(); 
         //****先得到网卡数目          
         int i = 0; 
         foreach(ManagementObject mo in moc) 
         {                         
            if((bool)mo["IPEnabled"] == true) 
            {                
               i++;                
            }             
            mo.Dispose(); 
         } 
         //***赋值给数组 
         ManagementClass mc_2 = new ManagementClass("Win32_NetworkAdapterConfiguration"); 
         ManagementObjectCollection moc_2 = mc_2.GetInstances(); 
         string []array = new string[i]; 
         int j = 0; 
         foreach(ManagementObject mo in moc_2) 
         {                         
            if((bool)mo["IPEnabled"] == true) 
            { 
               string delcolon = mo["MacAddress"].ToString(); 
               delcolon = delcolon.Replace(":","");                
               array[j] = delcolon; 
               j++;                
            }             
            mo.Dispose(); 
         } 
         return array; 
      }

另 WMI 获取本地MAC
1) Retrieve the MAC address:
ManagementClass mc = new ManagementClass
("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach(ManagementObject mo in moc)
{
if((bool)mo["IPEnabled"] == true)
Console.WriteLine("MAC address\t{0}", mo
["MacAddress"].ToString());
mo.Dispose();
}
