C#获取的CPU 序列号ID怎么都是一样的？

Question

  public string GetCpuInfo() 
           { 
               string strCpu = null; 
               ManagementClass myCpu = new ManagementClass("win32_Processor"); 
               ManagementObjectCollection myCpuConnection = myCpu.GetInstances(); 
               foreach (ManagementObject myObject in myCpuConnection) 
               { 
                   strCpu = myObject.Properties["Processorid"].Value.ToString(); 
                   break;
               } 
               return strCpu; 
           }
怎么在每台机子上获得都是一样CPU ID？都是 BFEBFBFF0001067A  是不是方法有错？
