ConvertTo-HashTable.ps1 Part 2
I wrote the previous blog in the middle of watching the video. The VERY next thing he did was to create 2 hashtables so my simple version of ConvertTo-HashTable.ps1 wouldn't work for that case. So I made a more sophisticated version:
# ConvertTo-hashTable.ps1
# Updated to create multiple hashtables
param(
[string]
$key,
$value
)
Begin
{
$hashTables = @()
foreach ($v in @($value))
{
$hashTables += @{}
}
$Script = $false
if ($value -is [ScriptBlock])
{
$Script = $true
}
}
Process
{
$thisKey = $_.$Key
for ($i = 0 ; $i -le $hashTables.Count; $i++)
{
$hash = $hashTables[$i]
if (@($Value)[$i] -is [ScriptBlock])
{
$hash.$thisKey = & @($Value)[$i]
}
else
{
$hash.$thisKey = $_.$(@($Value)[$i])
}
}
}
End
{
foreach ($hash in $hashtables)
{
Write-Output $hash
}
}
I've attached the script as well.
What this does is to emit multiple hashtables - one for each VALUE you want. So the way you would use this is:
$ht1,$ht2 = gwmi Win32_logicalDisk –Filter “DriveType = 3” | ConvertTo-HashTable DeviceId {$_.size - $_.freeSpace}, FreeSpace
I'm going to go back and finish watching the video. I may end up with a couple more versions before I'm through. ha ha.
