用C#获取硬盘序列号,CPU序列号,网卡MAC地址的源码

privatestring[]getmoc()
{
string[]str=newstring[3];
managementclassmccpu=newmanagementclass("win32_processor");
managementobjectcollectionmoccpu=mccpu.getinstances();
foreach(managementobjectminmoccpu)
{
str[0]=m["processorid"].tostring();
}

foreach(managementobjectminmochd)
{
if(m["deviceid"].tostring()=="c:")
{

break;
}
}

managementclassmcmac=newmanagementclass("win32_networkadapterconfiguration");
