验证计算机MAC地址进行软件授权是一种通用的方法,C#可以轻松获取计算机的MAC地址,本文采用实际的源代码讲述了两种获取网卡的方式,第一种 方法使用ManagementClass类,只能获取本机的计算机网卡物理地址,第二种方法使用Iphlpapi.dll的SendARP方法,可以获取 本机和其它计算机的MAC地址。
方法1:使用ManagementClass类

/// <summary> /// 获取网卡物理地址 /// </summary> /// <returns></returns> public static string getMacAddr_Local()
{ string madAddr = null;
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc2 = mc.GetInstances();
foreach (ManagementObject mo in moc2)
{
if (Convert.ToBoolean(mo["IPEnabled"]) == true)
{
madAddr = mo["MacAddress"].ToString();
madAddr = madAddr.Replace(\':\', \'-\');
}
mo.Dispose();
}
return madAddr;

1.需要给项目增加引用:System.Management,如图:
3.本方案只能获取本机的MAC地址;
方法2:使用SendARP类

//下面一种方法可以获取远程的MAC地址 [DllImport("Iphlpapi.dll")]
static extern int SendARP(Int32 DestIP, Int32 SrcIP, ref Int64 MacAddr, ref Int32 PhyAddrLen);
[DllImport("Ws2_32.dll")]
static extern Int32 inet_addr(string ipaddr);
/// <summary> /// SendArp获取MAC地址 /// </summary> /// <param name="RemoteIP">目标机器的IP地址如(192.168.1.1)</param> /// <returns>目标机器的mac 地址</returns> public static string getMacAddr_Remote(string RemoteIP)
{ StringBuilder macAddress = new StringBuilder();
try
{
Int32 remote = inet_addr(RemoteIP);
Int64 macInfo = new Int64();
Int32 length = 6;
SendARP(remote, 0, ref macInfo, ref length);
string temp = Convert.ToString(macInfo, 16).PadLeft(12, \'0\').ToUpper();
int x = 12;
for (int i = 0; i < 6; i++)
{
if (i == 5)
{
macAddress.Append(temp.Substring(x - 2, 2));
}
else
{
macAddress.Append(temp.Substring(x - 2, 2) + "-");
}
x -= 2;
}
return macAddress.ToString();
}
catch
{
return macAddress.ToString();
}

1.在程序开始添加包引入语句:using System.Runtime.InteropServices;
2.该方法可以获取远程计算机的MAC地址;
