Is there a way to get the sound that the sound card is playing directly from the hardware?
A:
some sound cars can select the output sound as mic, if that is acceptable then you could just google how to use the microphone...

I presume that this is Windows since you are using C#. Ignore this if you are using mono.
There is no officially supported way to do this in Windows. Some sound cards have a setting in the mixer that will set the wave record input to 'what you hear'. So on those cards, you could just set that setting and then record audio.
edit:
I should add that if your driver doesn't have built in support for recording what it's outputing, then you will need to write or purchase a driver that does. I've heard that TotalRecorder can do this.

That's an option but i don't want having the user to manually change settings the program should handle everything.

It's possible to programatically manipulate the mixer, although you may have to write unmanaged code to do it. And the mixer api is a pain to work with.

And what if my program is playing the sound itself ?

Then save the data before you play it, of course. That would be much easier.

The thing i want to do is play a youtube clip inside my program and the sound capture the sound of the movie. It should also work with sounds from other sources, but youtube is what i want to start with.

Total Recorder is the easiest general purpose way I know of to do this. This is a hard problem unless you write drivers for a living.

If you're really only trying to strip the sound from a YouTube video, you have a completely different (almost certainly easier) problem than trying to record from the sound card.

NAudio is a nice API for sound programming in C#. I'm only discovered it myself, but it might be able to record the output, though probably not...
