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.
