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

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

SendARP(Int32 DestIP, Int32 SrcIP,
ref
Int64 MacAddr,
ref

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();

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;
