思路是用加密程序对硬盘号，cpu号和MAC号取出字符串并加密产生一个序列号

每次程序启动后重新产生这个序列号并比对，如果一致则验证通过

using System;
using System.Collections.Generic;
using System.IO;
using System.Management;
using System.Text;
using System.Management.Instrumentation;

static string GetDeviceNumber()
        {
            string deviceinfo = "";
            string cpuInfo = "";
            //cpu序列号       
            ManagementClass cimobject = new ManagementClass("Win32_Processor");
            ManagementObjectCollection moc = cimobject.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                cpuInfo = mo.Properties["ProcessorId"].Value.ToString();
                deviceinfo = deviceinfo + cpuInfo.ToString();
            }
            //获取网卡硬件地址                
            ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc2 = mc.GetInstances();
            foreach (ManagementObject mo in moc2)
            {
                if ((bool)mo["IPEnabled"] == true)
                    deviceinfo = deviceinfo + mo["MacAddress"].ToString();
                mo.Dispose();
            }
            return deviceinfo;
        }
