How to concatenate array of integers into comma separated string

Question

I have two question, acually:

1. How to join array of integers into comma separated string? (1,2,3) => \"1,2,3\"
2. How to convert array of integers t

Answer 1

I don't if this is correct. Usually, they have powershell2. Just give this a little try.

$a = @()
$strArrayNum=""
for($i=0; $i -lt $arraylist.length; $i++ ){
  $strArrayNum += $element
  $strArrayNum = $i+1 -eq $arraylist.length ? "" : ","
}

$a = $strArrayNum.Split(",")
