Méthodes publiques

Méthode Description
Between ( double startNumber, double stopNumber ) : double

Generates a semi cryptographically strong random integer between specified values. i.e. [startNumber-stopNumber)
ByteBetween ( byte startNumber, byte stopNumber ) : byte

Generates a cryptographically strong 8-bit random integer between specified values. i.e. [startNumber-stopNumber)
GetBytes ( byte buffer ) : void

Fills an array of bytes with a cryptographically strong sequence of random values.

The length of the byte array determines how many cryptographically strong random bytes are produced.

This method is thread safe.
Int16Between ( short startNumber, short stopNumber ) : short

Generates a cryptographically strong 16-bit random integer between specified values. i.e. [startNumber-stopNumber)
Int24Between ( Int24 startNumber, Int24 stopNumber ) : Int24

Generates a cryptographically strong 24-bit random integer between specified values. i.e. [startNumber-stopNumber)
Int24Between ( System.UInt24 startNumber, System.UInt24 stopNumber ) : System.UInt24

Generates a cryptographically strong unsigned 24-bit random integer between specified values. i.e. [startNumber-stopNumber)
Int32Between ( int startNumber, int stopNumber ) : int

Generates a cryptographically strong 32-bit random integer between specified values. i.e. [startNumber-stopNumber)
Int64Between ( long startNumber, long stopNumber ) : long

Generates a cryptographically strong 64-bit random integer between specified values. i.e. [startNumber-stopNumber)
UInt16Between ( ushort startNumber, ushort stopNumber ) : ushort

Generates a cryptographically strong unsigned 16-bit random integer between specified values. i.e. [startNumber-stopNumber)
UInt32Between ( uint startNumber, uint stopNumber ) : uint

Generates a cryptographically strong unsigned 32-bit random integer between specified values. i.e. [startNumber-stopNumber)
UInt64Between ( ulong startNumber, ulong stopNumber ) : ulong

Generates a cryptographically strong unsigned 64-bit random integer between specified values. i.e. [startNumber-stopNumber)

Private Methods

Méthode Description
GetRandomNumberLessThan ( int maxValue ) : int

Returns a cryptographically strong number that is less the the supplied value

A number less than a negative number rolls down to int.MinValue, then to int.MaxValue if 0 is provided, 0 is returned

GetRandomNumberLessThan ( long maxValue ) : long

Returns a cryptographically strong number that is less the the supplied value

A number less than a negative number rolls down to long.MinValue, then to long.MaxValue if 0 is provided, 0 is returned

GetRandomNumberLessThan ( uint maxValue ) : uint

Returns a cryptographically strong number that is less than the the supplied value

if 0 is provided, 0 is returned

GetRandomNumberLessThan ( ulong maxValue ) : ulong

Returns a cryptographically strong number that is less than the the supplied value

if 0 is provided, 0 is returned
