Re: [.NET 2.0+] Rolling Dice

Great post! :thumb:
Randomness is, how unlikely it may seem, very hard to achieve. I do know that the one created by computer applications is simulated, though I don't know exactly how it's done.

I guess what I'm saying is; could explain how the Random class actually works? How is the random number generated? That'd be awesome to know :).

I'm happy to answer this question but this CodeBank thread is not really the place for it. I've asked the moderators to split it off into its own thread in the .NET D & A forum.

Re: Rolling Dice

The Random class uses a seed value to generate a pseudo-random sequence of numbers based on an algorithm. The sequence varies without apparent relationship as the seed value varies. It actually generates values in the range 0.0 <= R < 1.0 and the Next method performs some mathematics on that value to produce an Integer within a specified range. If you want to see exactly how it's done then I suggest that you install .NET Reflector and examine the class.

The System.Security.Cryptography namespace has types that can generate random values to a cryptographically-acceptable level of randomness, if you need really random.
