Remarks
Use the MersenneTwister class to represent a pseudo-_random
number generator that uses the Mersenne Twister algorithm of Takuji Nishimura and Makoto Matsumoto.
This generator has a very long period of 219937-1. This period is a Mersenne prime number (since 19937 is prime), whence its name. The algorithm is very fast and produces very good random sequences.
MersenneTwister can be used in place of the Random class to obtain pseudo-random numbers of a higher quality.
The Mersenne Twister is a linear random number generator. This makes it unsuitable for use in cryptography applications. To generate a cryptographically secure random number suitable for creating a random password, for example, use a class derived from RandomNumberGenerator such as RNGCryptoServiceProvider.
