Hello,

Im using WMI to get CPU information through Win32_Processor.
It  returns a collection but some items are "not valid".

....
foreach( ManagementObject oReturn in oReturnCollection )
{
   Console.WriteLine(oReturn["Manufacturer"].ToString());
   Console.WriteLine(oReturn["ProcessorId"].ToString());
}

If oReturn["ProcessorId"] does not "exist" it crash with error:
Additional information: Object reference not set to an instance of an object.

How can I test to see if  oReturn["ProcessorId"]  is set to an instance
befor I WriteLine(...) it?

Thanks,

Joao Rego
