I am trying to take the output of my foreach loop and apply the array to a string that reads on one line. Here is my code so far:
$upper = 65..90
$lower = 97..122
foreach ($i in $upper)
{
[char]$i
}
foreach ($i in $lower)
{
[char]$i
}
I'm guessing I need to convert the output of the scriptblock to a variable and use the -join option, but everywhere I look I'm struggling to find how to structure that. Any guidance would be appreciated.
For this particular case, ForEach(type convertToType) is very useful, here is a cool way to get your lower and upper case dictionary string:
$lowerDict = [string]::new(([int][char]'a'..[int][char]'z').ForEach([char]))
$upperDict = $lowerDict.ToUpper()
If you have access to PowerShell Core, it can be reduced to:
$lowerDict = [string]::new('a'..'z')
$upperDict = $lowerDict.ToUpper()
As for what you are struggling on, how to do it with what you currently have (a foreach loop). You can capture all the output from the loop first:
$upper = foreach ($i in 65..90) { [char]$i }
Now, $upper is an array of chars, then to convert it to string, you can either use -join (guessed right) or [string]::new(...) as I did on my previous example:
$upperDict = -join $upper
# OR
$upperDict = [string]::new($upper)
