Question

I have the following code. Random r works and gets me about 10% into the if. However rr doesn’t seem to work. It always returns 0. What am I doing wrong?

I want to choose between two choices randomly only 10% of the time. This is in an asp.net app. The code gets executed on button click.

        Random r = new Random();
        Random rr = new Random();

        int randomnum = r.Next(0, 100);
        if (randomnum <= 10)
        {

            int randompick = rr.Next(0, 2);
            if (randompick == 0)
            {

Answer 1

If you are happy with the outer loop’s randomness, consider

int randompick = randomnum % 2;

instead of the nested Random object.
