Question

I need a simple way of checking how much ram and fast the CPU of the host PC is. I tried WMI however the code I’m using

 private long getCPU()
 {
    ManagementClass mObject = new ManagementClass("Win32_Processor");
    mObject.Get();
    return (long)mObject.Properties["MaxClockSpeed"].Value;

 }

Throws a null reference exception. Furthermore, WMI queries are a bit slow and I need to make a few to get all the specs. Is there a better way?

using System.Management;

public uint CPUSpeed()
{
  ManagementObject Mo = new ManagementObject("Win32_Processor.DeviceID='CPU0'");
  uint sp = (uint)(Mo["CurrentClockSpeed"]);
  Mo.Dispose();
  return sp;
}

RAM can be found in this SO question: How do you get total amount of RAM the computer has?
