Next(Int32, Int32)

Gets a random integer that is within a specified range.

Declaration
int Next(int lowerBound, int upperBound)
Parameters
Type Name Description
Int32 lowerBound

The inclusive lower bound of the random number to be generated.
Int32 upperBound

The exclusive upper bound of the random number to be generated. It must be greater than or equal to lowerBound.
Returns
Type Description
Int32

A 32-bit signed integer that is greater than or equal to lowerBound and less than upperBound; that is, the range of return values ordinarily includes lowerBound but not upperBound. If upperBound equals to lowerBound, lowerBound is returned.
Exceptions
Type Condition
ArgumentOutOfRangeException

Thrown when upperBound is less than lowerBound.

Next(Int32)

Gets a non-negative random integer that is less than the specified upperBound.

Declaration
int Next(int upperBound)
Parameters
Type Name Description
Int32 upperBound

The exclusive upper bound of the random number to be generated. It must be greater than or equal to 0.
Returns
Type Description
Int32

A 32-bit signed integer that is greater than or equal to 0 and less than upperBound; that is, the range of return values ordinarily includes 0 but not upperBound. However, if upperBound equals to 0, upperBound is returned.
Exceptions
Type Condition
ArgumentOutOfRangeException

Thrown when upperBound is less than 0.
