I'm trying to convert a string that looks like this,
2,3,4,5,6,20..30
to an array of integers. Here is the code I currently have:
[string]$a = "2,3,4,5,6,7"
[array]$b = $a.split(",")
[array]$c = foreach($number in $b) {([int]::parse($number))}
Which works, but not for the range of 20..30. How do I get that part working?
You can use the Invoke-Expression cmdlet to interpret the 10..30 bit, if the [int]::Parse() method call fails.
Here is a complete, working sample.
[string]$a = "2,3,4,5,6,7,10..30";
[array]$b = $a.split(",");
[array]$c = foreach($number in $b) {
try {
[int]::parse($number)
}
catch {
Invoke-Expression -Command $number;
}
}
$c;
One-liner (just for fun):
$c = "2,3,4,5,6,7,10..30".split(',') | % {iex $_}
Inside of a string, your .. is taken as-is and is not expanded to a range.
So $a = "1 .. 5" is actually 1 .. 5 and not 1, 2, 3, 4, 5.
To make your program work, you will have to tokenize not only on , but also on .. and then expand.
