How to get CPU frequency in c#

Question

How can I get in c# the CPU frequency (example : 2Ghz) ? It\'s simple but I don\'t find it in the environnement variables. Thanks :)

Try this code

using System.Management;

uint currentsp , Maxsp;
public void CPUSpeed()
{
   using(ManagementObject Mo = new ManagementObject("Win32_Processor.DeviceID='CPU0'"))
   {
       currentsp = (uint)(Mo["CurrentClockSpeed"]);
       Maxsp = (uint)(Mo["MaxClockSpeed"]);
   }
}
