In french: TableauIntersection

Returns an array corresponding to the intersection of two arrays.

The following arrays can be handled:

One-dimensional array of simple elements (int, real, string).
One-dimensional array of structures.

Example

// First array of integers
arrMyArray1 is array of int
ArrayAdd(arrMyArray1, 1)
ArrayAdd(arrMyArray1, 2)
ArrayAdd(arrMyArray1, 1)
ArrayAdd(arrMyArray1, 3)

// Second array of integers
arrMyArray2 is array of int
ArrayAdd(arrMyArray2, 3)
ArrayAdd(arrMyArray2, 5)
ArrayAdd(arrMyArray2, 8)
ArrayAdd(arrMyArray2, 1)

// Intersection array
arrMyIntersection is array of int
arrMyIntersection = ArrayIntersect(arrMyArray1, arrMyArray2)
// the result is 3;1

Syntax

<Result> = ArrayIntersect(<First WLanguage array> , <Second WLanguage array>)

<Result>: Array

Array variable that contains the result of the intersection.

<First WLanguage array>: Array

Name of the Array variable that corresponds to the first array to use. This array must be a one-dimensional array. This array will not be modified.

<Second WLanguage array>: Array

Name of the Array variable that corresponds to the second array to use. This array must be a one-dimensional array. This array must be of the same type as the array specified with the <First WLanguage array> parameter. This array will not be modified.

Remarks

If an array contains several duplicates, these duplicates will not be kept.
The resulting array will not be sorted, even if the original arrays are.
