Count length of array and return 1 if it only contains one element

arrays powershell

A couple other options:

Use the comma operator to create an array:

$cars = ,"bmw"$cars.GetType().FullName# Outputs: System.Object[]

Use array subexpression syntax:

$cars = @("bmw")$cars.GetType().FullName# Outputs: System.Object[]

If you don't want an object array you can downcast to the type you want e.g. a string array.

 [string[]] $cars = ,"bmw" [string[]] $cars = @("bmw")

arrays powershell

Instead of writing echo $cars.length write echo @($cars).length

arrays powershell

declare you array as:

$car = array("bmw")

EDIT

now with powershell syntax:)

$car = [array]"bmw"
