Didn't feel what is the difference between when using, as shown in the following code:

 static int Main (string [] args) {
ManagementClass diskClass=
New ManagementClass (" Win32_LogicalDisk "); 
ManagementObjectCollection disks=
DiskClass. GetInstances (); 
ManagementObjectCollection. ManagementObjectEnumerator 
DisksEnumerator=
Disks. GetEnumerator (); 
While (disksEnumerator. MoveNext ()) {
ManagementObject disk=(ManagementObject) disksEnumerator. Current; 
//ManagementBaseObject disk=disksEnumerator. Current;//this can also be ah, why do they go? 
Console. WriteLine (
"Disk found:" + Disk (" deviceid ")); 
} 
return 0; 
}

Maybe just name is different

In your ManagementObject F12 and see if he's inherited from ManagementBaseObject

you on ManagementObject F12, and see that he inherited from ManagementBaseObject

Subclass is no doubt, I just don't understand why forced into subclasses, this is in the MSDN example,

Subclass is no doubt, I just don't understand why forced into subclasses, this is in the MSDN example,

Because parents have children without methods and properties,
And since he could into subclasses that into method, is likely to be a subclass,
