Turn a non-delimited string into an array in powershell?

Alright, so I mention this in most of my questions about powershell, but I am new to it.

If I have a string, how do  I convert it to an array.  Example below:
String:
aNgie#35

Needs to become:
"a","N","g","i","e","#","3","5"

I was looking at the split function, but how do I use that if we aren't using a delimiter?

I believe that if you pass an empty string to split as the delimiter it will split each character individually as you want.  Then join back with quotes between and before and after.


'"' + mystring.Split("").Join('","') + '"'

That didn't work.  I thought of something like that myself.  I tried to do something like the following

$strRandom = some combination of letters numbers and symbols
$arrRandomn = $strRandom.split("").join(",")

also tried this

$arrRandomn = $strRandom.split().join(",")

It says system.object[]  doesn't contain a method named 'Split'.

Try adding a tostring call:

$arrRandomn = '"' + $strRandom.tostring().split("").join('","') + '"'

I can't test it myself right now (sorry) but there seems to be a ToCharArray function that many people use for exploding a string into an array of characters.  I can't find source code for ToCharArray so maybe it is built in.  Please see if either of these work for you:

$arrRandomn = '"' + $strRandom.ToCharArray().join('","') + '"' 

or

$arrRandomn = '"' + $strRandom.tostring().ToCharArray().join('","') + '"'

So, the

"aNgie#35" -split ""

based solutions are not quite correct, as they produce an array of 10 elements (first and last are empty strings).

My

"aNgie#35"  -split "(?<=.)(?=.)"  

produces the correct array of 8 elements.

If we change the first priod (.) to any other regex expression, such as \d for digits, we can split the following string at numbers, but still keep the numbers in the result:

"gg7kjh8j9k4j5j8" -split "(?<=\d)(?=.)"
gg7
kjh8
j9
k4
j5
j8

Try this.
$string = "aNgie#35"
$arrLetters += $string.GetEnumerator()

Open in new window

This should put each letter as a new item of the $arrLetters array. Or if you just want to know how to split up a string, you can use the GetEnumerator() function ($string.GetEnumerator()) without putting it into an array.
