Hello,

I am coming with electronic backround, so I need some help with C# code.

I need to take a square wave from the sound port(microphone plugin) and converts it to DEC value.

for exmaple the wave 0001 will be number 1, or 0011 will be the number 3 (__|-|-| , LOW LOW HIGH HIGH)

Thank you.

Let me help you, help me.
There are software like Zelscope wich are - "sound card osilloscope". They gives the the wave from the microphone input. I connected the IR detector component and I was saw the square wave from a simple TV remote.
How do I build software something like this?
Actuly all is need to do is to count the time between every HIGH signal ot anather.
Thank you again.

I don't know how to do it except I know how not to do it. In mult-processign operating systems such as Windows and Unix/Linux, limited resources such as keyboard, mouse, monitor and sound port(s) are not directly accessible to application software. So you must use Windows or at least some kind of device driver. There are DirectX things such as DirectSound that might help.
