메소드	설명
MT19937Generator ( ) : System	Initializes a new instance of the MT19937Generator class, using a time-dependent default seed value.
MT19937Generator ( int seed ) : System	Initializes a new instance of the MT19937Generator class, using the specified seed value.
MT19937Generator ( uint seed ) : System	Initializes a new instance of the MT19937Generator class, using the specified seed value.
Next ( ) : int	Returns a nonnegative random number less than MaxValue.
Next ( int maxValue ) : int	Returns a nonnegative random number less than the specified maximum.
Next ( int minValue, int maxValue ) : int	Returns a random number within the specified range.
NextBoolean ( ) : bool	Returns a random Boolean value. Buffers 32 random bits (1 uint) for future calls, so a new random number is only generated every 32 calls.
NextBytes ( byte buffer ) : void	Fills the elements of a specified array of bytes with random numbers. Each element of the array of bytes is set to a random number greater than or equal to 0, and less than or equal to Byte.MaxValue.
NextDouble ( ) : double	Returns a nonnegative floating point random number less than 1.0.
NextDouble ( double maxValue ) : double	Returns a nonnegative floating point random number less than the specified maximum.
NextDouble ( double minValue, double maxValue ) : double	Returns a floating point random number within the specified range.
NextInclusiveMaxValue ( ) : int	Returns a nonnegative random number less than or equal to MaxValue.
NextUInt ( ) : uint	Returns an unsigned random number.
Reset ( ) : bool	Resets the MT19937Generator, so that it produces the same pseudo-random number sequence again.

GenerateNUInts ( ) : void	Generates MT19937Generator.N unsigned random numbers. Generated random numbers are 32-bit unsigned integers greater than or equal to UInt32.MinValue and less than or equal to UInt32.MaxValue.
ResetBySeedArray ( ) : void	Extends resetting of the MT19937Generator using the seedArray.
ResetGenerator ( ) : void	Resets the MT19937Generator, so that it produces the same pseudo-random number sequence again.
