How do I find and get value from multi dimensional array in powershell?-CodePudding

Basically I have an array that looks something like

areaCodes = @ (
 @("310", "LA"),
 @("212", "NY"),
 @("702", "LV")
)

I would like to have it so that for example if I have a variable $code = $212 Find if it is in the list, and if is, get the value associated with it.

Something like

if($areaCodes.contains($code))
{
 WRITE-HOST $areaCodes[1]
}

and this would output NY

How do I do this in powershell? Or is there are more efficient way to do this?

CodePudding user response：

You need to enumerate all arrays inside your array for this to work, for example:

($areaCodes | Where-Object { $_ -contains $code })[1] # => NY

Or using an actual loop:

foreach($array in $areaCodes) {
    if($array -contains $code) {
        $array[1]
        break
    }
}

But taking a step back, a hash table seems a lot more appropriate for your use case:

$code = 212
$areaCodes = @{
    310 = "LA"
    212 = "NY"
    702 = "LV"
}

$areaCodes[$code] # => NY
