这是一个C#获取硬盘序列号,CPU序列号,网卡MAC地址的代码，发出来，给需要的朋友！

privatestring[]GetMoc()

 { string[]str=newstring[3]; ManagementClassmcCpu=newManagementClass("win32_Processor");

ManagementObjectCollectionmocCpu=mcCpu.GetInstances();

 foreach(ManagementObjectminmocCpu)

{ str[0]=m["ProcessorId"].ToString(); }

ManagementClassmcHD=newManagementClass("win32_logicaldisk");

ManagementObjectCollectionmocHD=mcHD.GetInstances();

foreach(ManagementObjectminmocHD)

 { if(m["DeviceID"].ToString()=="C:")

{ str[1]=m["VolumeSerialNumber"].ToString(); break; } }

ManagementClassmcMAC=newManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollectionmocMAC=mcMAC.GetInstances();

foreach(ManagementObjectminmocMAC) { if((bool)m["IPEnabled"])

{ str[2]=m["MacAddress"].ToString(); break; } } returnstr; }
