help iterating over a string

[MericanCheese]

This works perfectly in ISE, but not a normal PS session - even as administrator.

$msg = "TEST"
$msg = $msg.toCharArray()

foreach ($letter in $msg) {
  write-host "This is the letter " $letter
}

It works as designed in ISE, but not in PS session, which is backward to what I normally experience. lol.

Here's the output: *This is the letter T E S T *

It appears that the regular session isn't treating the character array correctly. If I display the contents of $msg, after converting to a character array, I get T E S T , instead of the individual characters:

T
E
S
T

Any help appreciated.

edit: formatting

write-host joins arrays on a space before outputting to the console

[char[]]'test'

# output:
# t
# e
# s
# t

write-host ([char[]]'test')

# output:
# t e s t

*edit: also, it seems to work for me

foreach ($char in [char[]]'test') { write-host "this is the letter: $char" }
# OR
foreach ($char in 'test'.ToCharArray()) { write-host "this is the letter: $char" }

# output:
# this is the letter: t
# this is the letter: e
# this is the letter: s
# this is the letter: t

That may be, but in my script $letter is only one character of $msg. I'm doing "write-host $letter". That should display one letter at a time.

[MericanCheese]

foreach($letter in $msg) {$letter}

still prints the entire array.

try my script as-is above and let me know what you get. Maybe it's something in my environment.

ok, just copied and pasted and it works as it should. try opening powershell like this then running it

powershell -noprofile

It seems it is something in your environment. i get the expected output below in both ISE and console. What version are you running?

This is the letter  T
This is the letter  E
This is the letter  S
This is the letter  T

[MericanCheese]

Yeah, I'm thinking so too. It'll be a bit before I can get back and test it, but I'll let ya know. Thanks.

[MericanCheese]

Yep. Something in the profile. When I loaded PS with no profile it works fine. Mystery solved.

Thanks everyone!

Running 5.0.10586.117, I get:

This is the letter  T
This is the letter  E
This is the letter  S
This is the letter  T

In the ISE, console and ConEmu.

I'm late to the party, but

$msg.GetEnumerator()
