Remarks

The EzRand class can be used to generate random numbers or bytes using a variety of algorithms and implementations.

To begin first set the Algorithm property to the desired value. This property specifies the algorithm and implementation that will be used to generate the number or bytes. Possible choices include ISAAC, the Microsoft Crypto API, and platform specific random and secure random implementations.

Next set Min and Max to define the acceptable range of values when generating an integer. The Seed property may optionally be set. Then simply call GetNextInt to generate a random number. the RandInt property will be populated with the generated value.

To generate a random set of bytes set RandBytesLength to the desired number of bytes and call GetNextBytes.
