The RandomNumberGenerator class is the abstract base from which random number generator implementations inherit. Implementation classes are instantiated with the Create( ) method, which accepts the name of an implementation as a String argument. An instance of the default algorithm is created if no name is specified; the system administrator can configure the default algorithm.

The GetBytes( ) method populates a System.Byte array with random values; the array to fill is the sole argument to the method. The GetNonZeroBytes( ) method populates a System.Byte array with random values, none of which will be 0.

The .NET Framework class library includes the RNGCryptoServiceProvider class, which is the default implementation.
