Name
Random
Synopsis
This class encapsulates a pseudorandom number (one chosen from a
list of pregenerated numbers, but that is statistically random).
After creating an instance of this class, use the Next()
,
NextDouble()
, or NextBytes()
method to return random information. NextDouble()
returns a fraction value between 0.0 and 1.0, while Next()
returns an integer between 0 and the maximum bound that you specify. NextBytes()
fills a supplied array of bytes with random numbers.
When creating a Random
object, you supply a seed value to the
constructor, which determines the
place on the list from where the random number is drawn. If you
supply the same seed value to multiple
Random
instances, you will receive the
same random number.
Computers are incapable of generating truly
random numbers, and Random
should not be
used for cryptographic algorithms.
For a cryptographically strong random number generator, see the
System.Security.Cryptography.RandomNumberGenerator
in the .NET Framework SDK Documentation.
