Question

I’ve read about it on a message board – Random class isn’t really random. It is created with predictable fashion using a mathematical formula.

Is it really true? If so, Random isn’t really random??

Answer 1

As others have already said, Random creates pseudo-random numbers, depending on some seed value. It may be helpful to know that the .NET class Random has two constructors:

 Random(int Seed)

creates a random number generator with a given seed value, helpful if you want reproducible behaviour of your program. On the other hand,

 Random()

creates a random number generator with date-time depending seed value, which means, almost every time you start your program again, it will produce a different sequence of (pseudo-)random numbers.
