Powershell Multidimensional Arrays

Question

I have a way of doing Arrays in other languagues like this:

$x = "David"
$arr = @()

$arr[$x]["TSHIRTS"]["SIZE"] = "M"

This generates an error.

Answer 1

You are trying to create an associative array (hash). Try out the following sequence of commands

$arr=@{}
$arr["david"] = @{}
$arr["david"]["TSHIRTS"] = @{}    
$arr["david"]["TSHIRTS"]["SIZE"] ="M"
$arr.david.tshirts.size

Note the difference between hashes and arrays

$a = @{} # hash
$a = @() # array

Arrays can only have non-negative integers as indexes
