How do you randomly zero a bit in an integer?

Question

Updated with newer answer and better test

Let\'s say I have the number 382 which is 101111110.

How could I randomly turn a bit which is not 0 to

Answer 1

EDIT: Fixed some logic.

BitArray bits = new BitArray(new int[] { number } );

randomIndex = new Random().Next(32);

// check if bit is true, if not, goes to next bit and wraps around as well.
for(int i = 0; i < 32; i++)
{
    if(bits[randomIndex] == false)
    {
    randomIndex = (randomIndex + 1) % 32;
    }
    else
    {
        break;
    }
}

bits[randomIndex] = false;
