PowerTip: The Finer Points of Finessing an Array

Summary: Learn how to replace items in an array and how to sort an array.

I need to replace the “2” with “12” in the $array variable shown here:

$array = "1","2","3","4"

How can I do this?

1. $array=[regex]::replace($array,"2","12")
2. $array = $array -replace "2","12"
3. $array.SetValue("12",1)

I have an array defined in the $array variable shown here.

$array = 2,5,9,12,3,5

What is the easiest way to sort the array?

1. Sort the array by using the sort static method from the [array] .NET Framework class.

[array]::sort($array)

2. Pipe the array to the Sort-Object cmdlet, and store the results back in the $array variable.

 $array = $array | sort
