Find value in array of objects after importing from CSV file - powershell

Question

I am reading in values from a CSV file using Import-Csv which include server name, ip address and a note field
Is there a built in mechanism to find an object based on the server name without having to loop through the entire array?
I'm keeping the array in memory to use multiple times.
$ServerList = Import-Csv ".\ServerList.csv"
I'm creating a GUI with Powershell Studio and populating a dropdown with all the server names read in from the file. The user will choose a server from the dropdown and there will be buttons to perform actions on that server using the IP address read in.

Answer 1

You could populate a hashtable with the data from the CSV, using the servername as key:
$ServerList = #{}
Import-Csv '.\ServerList.csv' | % { $ServerList[$_.ServerName] = $_ }
That way you can access the data like this:
$server = 'foo'
$ServerList[$server].IPAddress

Answer 2

$csv = Import-csv my.csv | where {$_.servername -eq "MyServer"}
foreach ($server in $csv) {
# Do your thing
}

Answer 3

If you need to call it multiple times you can use a function that you call when the user selects a server:
function getServer($selectedServer){
$ServerInfo = Import-Csv ".\ServerList.csv" | where {$_.servername -eq $selectedServer}
return $ServerInfo
}
When the user makes a selection the code would like like so:
$Server = getServer('ABCSRV')
Then $Server.IP and $Server.Notes would have the information from that specific server, granted that you have these columns in place in your csv.
