Examples

This example uses the IsArray function to check if several variables refer to an array.

Dim firstArray(4), secondArray(3) As Integer
Dim thisString As String = "Test"
Dim arrayCheck As Boolean
arrayCheck = IsArray(firstArray)
arrayCheck = IsArray(secondArray)
arrayCheck = IsArray(thisString)
' The first two calls to IsArray return True; the third returns False.

IsArray returns True if the variable points to an array; otherwise, it returns False. IsArray is especially useful with objects that might contain arrays.
