Great, but why do you think inpout32 is "not directly"? What is "directly" then? Writing a kernel-mode driver from scratch? Good luck, but then don't tag it "C#"!

if i use inpout32 then generate a pwm wave then it's frequency is dependent upon PC's Speed that's why i write 'directly'........

As your criteria for "direct" access are not clear (please see my comment to the question), please see what solutions were suggested in CodeProject, there is a good number of them:

I assume you did not find anything by Google or Bing, so I'm not going to advise you how to do such search. :-)
