Instantiating the random number generator To generate a cryptographically secure random number, such as one that's suitable for creating a random password, use the RNGCryptoServiceProvider class or derive a class from. Addison-Wesley, Reading, MA, third edition, 1997. The Art of Computer Programming, Volume 2: Seminumerical Algorithms. Knuth's subtractive random number generator algorithm. The current implementation of the Random class is based on a modified version of Donald E. The chosen numbers are not completely random because a mathematical algorithm is used to select them, but they are sufficiently random for practical purposes. Pseudo-random numbers are chosen with equal probability from a finite set of numbers. ' The example displays output similar to the following:
Five random integers between 50 and 100:Ĭonsole.WriteLine("Five random byte values:") Ĭonsole.WriteLine("Five random integer values:") įor (int ctr = 0 ctr ^ malePetNames = ", femalePetNames(fIndex)) Five random integers between 0 and 100: The example displays output like the following: Generate and display 5 random floating point values from 0 to 5.Ĭonsole::WriteLine("Five Doubles between 0 and 5.") Generate and display 5 random floating point values from 0 to 1. Generate and display 5 random integers from 50 to 100.Ĭonsole::WriteLine("Five random integers between 50 and 100:") Generate and display 5 random integers between 0 and 100.//Ĭonsole::WriteLine("Five random integers between 0 and 100:") Generate and display 5 random integers.Ĭonsole::WriteLine("Five random integer values:") Generate and display 5 random byte (integer) values.Ĭonsole::WriteLine("Five random byte values:")
Instantiate random number generator using system-supplied value as seed. The following example creates a single random number generator and calls its NextBytes, Next, and NextDouble methods to generate sequences of random numbers within different ranges.
