How “good” is this method for generating random numbers?

Question

I was searching on google for RNGCryptoServiceProvider with examples on how to limit the range between Max and Min, and still get an even distribution. Before I used modulo oper

Answer 1

It's a better practice to seed your random number generator just one time in your application. I suggest you create a static class for random number generation. The random generation object can yield even distribution just by normal usage. I don't know whats the benefit of seeding the generator with RNGCryptoServiceProvider. I prefer using the time as seeding method as usual. Therefore the following code is my suggestion:

int randomNumber=Rand.get(min,max);

public static class Rand
{
    private static Random rnd;
    static rand()
    {
        rand=new Random(DateTime.Now.Ticks);
    }
    public static int get(int min,int max)
    {
        return rnd.Next(min,max);
    }
}
