C# Grabbing sound output of soundcard and storing it as a varible

Hi. After much reading on the subject, I still can't find any thing useful to me. What i'm trying to do is get a reading from the sound card as it plays an audio file. I have some experience in c# and tried several different libaries, but just cant find how to do this. Im running a very powerful win7 64bit pc. I want to grab the digital outputs the soundcard makes when it plays the wave file, simular to what happens when a sine table is shown. I just want a int I can assign values to. wav file is 32bit mono For example. I have mediocre experience with c#.

public int sound_level ; 

public void sound_analize()

{ 

if (sound_level ==0;) //no sound 

{do something;
 }

if (sound_level == 50)//low sound

{do something;

}

if (sound_level = 100)//meduim sound level

{do something else;

}

if (sound_level = 200)//loud sound

{do something else;

}

}

so, for example. no noise could be 0-49
50-99 low sound
100 - 199 med sound
200+ loud sound
It doesnt matter what these numbers are as long as I can detrmine some sort of range between nosound,lowsound,medsound and highsound.
Here we see I just need a way to meausure the noise level of the soundcard as It is playing the wav file and store it into a int called sound_level.

Help much welcome

Thanks
