How to determine the hardware (CPU and RAM) on a machine?

Question

I\'m working on a cross platform profiling suite, and would like to add information about the machine\'s CPU (architecture/clock speed/cores) and RAM(total) to the report of

Answer 1

I've written some code which uses the WMI service to get the Max Clock Speed, I know it's VB.net but it shows the idea:

''' 

''' Use WMI to get the Clock Speed in Hz
''' 
Public Function GetMaxClockSpeedInHz() As Double
    Dim manObj = New ManagementObject("Win32_Processor.DeviceID='CPU0'")
    manObj.Get()
    GetMaxClockSpeedInHz = Convert.ToInt32(manObj.Properties("MaxClockSpeed").Value)
End Function
