Question

This method is pretty much copied from a java program, but I have worries it doesn’t work as intended in c#
if ID is a byte, what does this do?

public int getBit(int position)
    {
        return (ID >> (position - 1)) & 1;
    }

Answer 1

Extract from the ID the bit at the position passed.
Position should be 1-8
Returns the bit value (0-1)

For example:

ID = 128;  // 10000000
getBit(8); // returns 1

ID = 127;  // 01111111
getBit(8); // returns 0
