一段获得网卡地址和CPU序列号的代码,可以用来做软件许可证用

 右键当前程序集下的“引用”，选择添加引用，在“.NET”选项卡中选择System.Management，点击确定即可！

下面是获取MAC地址代码：

 private static string  GetMac()
        {
            string mac = "";
            ManagementClass mcMAC = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection mocMAC = mcMAC.GetInstances();
            foreach (ManagementObject m in mocMAC)
            {
                if ((bool)m["IPEnabled"])
                {
                    mac= m["MacAddress"].ToString();
                }
            }
            return mac;
        }

 

 下面是获取CPU序列号代码：

  public string GetCpuID()
        {
            try
            {
               // 获取CPU序列号代码
                string cpuInfo = "";//cpu序列号
                ManagementClass mc = new ManagementClass("Win32_Processor");
                ManagementObjectCollection moc = mc.GetInstances();
                foreach (ManagementObject mo in moc)
                {
                    cpuInfo = mo.Properties["ProcessorId"].Value.ToString();
                }
                moc = null;
                mc = null;
                return cpuInfo;
            }
            catch
            {
                return "unknow";
            }
            finally
            {
            }

        }
