I don't have access to a multi-socketed computer, so I am unsure if the following will get the grand total of processors and logical processors. I assume ManagementObjectSearcher will return an instance for each socketed CPU and I just keep a running total?

int totalCPUs = 0; int totalLogicalCPUs = 0;

ManagementObjectSearcher mos = new ManagementObjectSearcher("Select * from Win32_ComputerSystem"); foreach (var mo in mos.Get()) { string num = mo.Properties["NumberOfProcessors"].Value.ToString(); totalCPUs += Convert.ToInt32(num);

num = mo.Properties["NumberOfLogicalProcessors"].Value.ToString(); totalLogicalCPUs += Convert.ToInt32(num);

}
