Square Brackets in Switch Command 1

[mvvilleza]

Hi all,

Can i use square brackets with the switch command? Eg.

$a=5
switch($a)
{
[1-9]{$a="0"+$a}
}
$a

My desired output is 05.

You can't do it directly, but you can use expressions for comparisons so the following works:

switch ($a)
{
   {($_ -ge 1) -and ($_ -le 9)} {$a = "0" + $a}
}

Just out of curiosity, are you trying to write code to zero pad or some other way format strings? If so, there are probably existing commands to do that for you.

Just as a quick example, if you wanted to 0 pad a number out to 2 digits:

$a = 5
"{0:0#}" -f $a

Thanks crobin1, your solution is great.

To EBGreen,

You are correct, i'm trying to add a 0 to a single digit number from 1 to 9. i just assigned 5 in $a, if you notice the question is about square brackets in a switch command.

I understood the question, and crobin1 had already provided a good answer. I was just suggesting an alternate solution to what you were trying to do.
