获取CPU编号和MAC地址

首先要引用 System.Management.dll

//取CPU编号
     public string GetCpuID()
      {
          try
          {
              ManagementClass mc = new ManagementClass("Win32_Processor");
              ManagementObjectCollection moc = mc.GetInstances();
  
              string strCpuID = null;
             foreach (ManagementObject mo in moc)
             {
                 strCpuID = mo.Properties["ProcessorId"].Value.ToString();
                 break;
             }
             return strCpuID;
         }
         catch
         {
             return "";
         }

     }

     //获取网卡mac地址
     public string GetMac()
     {
         try
         {
             ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration");
             ManagementObjectCollection queryCollection = query.Get();
             foreach (ManagementObject mo in queryCollection)
             {
                 if (mo["IPEnabled"].ToString() == "True")
                     return mo["MacAddress"].ToString();
             }
             return "";
         }
         catch
         {
             return "";
         }
     }
