Is it possible in c# like in c++, to write to file bit by bit. for exmaple write one bit every iteration of for loop.

 void QT (int MINX, int MAXX,int MINY, int MAXY){
    short val = (short)normalizedImg[MINX, MINY];
    for(int x = MINX; x < MAXX; x++){
        for(int y = MINY; y < MAXY; y++){
            if (val != (short)normalizedImg[x,y])
                //Math.Pow(val - (short)normalizedImg[x, y], 2) > Math.Pow(T, 2)
                { 
                //writebit(1);
                QT(MINX,(MINX+MAXX)/2,MINY,(MINY+MAXY)/2);
                QT(MINX,(MINX+MAXX)/2,(MINY+MAXY)/2,MAXY);                
                QT((MINX+MAXX)/2,MAXX,MINY,(MINY+MAXY)/2);
                QT((MINX+MAXX)/2,MAXX,(MINY+MAXY)/2,MAXY); 
                return;
                }
            }

        }
        //Writebit(0)

    }

The problem is if I'd do this with the help of string, things get very slow very fast.

It is possible byte by byte, not bit by bit. If you want to do so, you must accumulate the bits yourself. use bitwise or (|) and shift operations << or >> depending whether you add new bits to the right or left. – Olivier Jacot-Descombes Oct 21 '17 at 18:55
Will try this, thank you – Rok Potočnik Oct 21 '17 at 18:59
