Method

Arrays.Shuffle

Description

Shuffles (rearranges randomly) the elements of an array.

Usage

array.Shuffle

Part	Type	Description
array	Any valid data type	The array whose elements will be shuffled.

Notes

Shuffle works on arrays of any data type and any number of dimensions. It is based on a random number. An element of the original array has a roughly equal chance of appearing in any cell of the array after the Shuffle, regardless of the size and number of dimensions of the array.

A Fisher-Yates Shuffle is used. There is no ability to control the seed.

Sample code

Shuffle a one-dimensional array:

Var values() As Integer = Array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
values.Shuffle

Var result As String
For Each item As Integer In values
  result = result + item.ToString
Next

Shuffle a two-dimensional array:

Var myArray(5, 5) As Text
For i As Integer = 0 To 5
  For j As Integer = 0 To 5
    myArray(i, j) = i.ToString + j.ToString
  Next
Next
myArray.Shuffle
