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?

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
