Merge Variables to one Object - powershell

Question

I have multiple variables, containing Information about my Servers. e.g
PS Z:\Powershell-Scripts> $AllRam
Computername RAM
------------ ---
ServerA 14.00
ServerB 80.00
ServerC 64.00
ServerD 48.00
ServerE 72.00
PS Z:\Powershell-Scripts> $AllProcessor
ComputerName ProcessorCount LogicalProcessors
------------ -------------- -----------------
ServerA 2 4
ServerB 2 32
ServerC 2 24
ServerD 1 12
ServerE 2 24
I have about 10 Variables containing different information.
Now I would like to merge them, so that I have one big Variable with all the information. So the example above should look like this in the end:
ComputerName ProcessorCount LogicalProcessors RAM
------------ -------------- ----------------- ---
ServerA 2 4 14.00
ServerB 2 32 80.00
ServerC 2 24 64.00
ServerD 1 12 48.00
ServerE 2 24 72.00
How could I achieve that? The ComputerName column exists in all Variables and all Servers exist in all Variables.

Answer 1

Here's one way to do it.
Foreach ($item in $AllProcessor) {
$RamItem = $AllRam.Where({$_.ComputerName -eq $item.ComputerName},'first')
Add-Member -MemberType NoteProperty -Name 'RAM' -Value $RamItem.Ram -InputObject $item
}
Here's another if you needed to create a new object without modifying existing one.
$ALLItems = Foreach ($item in $AllProcessor) {
$RamItem = $AllRam.Where( { $_.ComputerName -eq $item.ComputerName }, 'first')
[PSCustomObject]#{
ComputerName = $item.ComputerName
ProcessorCount = $item.ProcessorCount
LogicalProcessor = $item.LogicalProcessor
Ram = $RamItem.Ram
}
}
Result
Data used for reference
$AllRam = #(
[PSCustomObject]#{ComputerName = 'ServerA'; RAM = '14.00' }
[PSCustomObject]#{ComputerName = 'ServerB'; RAM = '80.00' }
[PSCustomObject]#{ComputerName = 'ServerC'; RAM = '64.00' }
[PSCustomObject]#{ComputerName = 'ServerD'; RAM = '48.00' }
[PSCustomObject]#{ComputerName = 'ServerE'; RAM = '72.00' }
)
$AllProcessor = #(
[PSCustomObject]#{ComputerName = 'ServerA'; ProcessorCount = 2; LogicalProcessor = 4 }
[PSCustomObject]#{ComputerName = 'ServerB'; ProcessorCount = 2; LogicalProcessor = 32 }
[PSCustomObject]#{ComputerName = 'ServerC'; ProcessorCount = 2; LogicalProcessor = 24 }
[PSCustomObject]#{ComputerName = 'ServerD'; ProcessorCount = 1; LogicalProcessor = 12 }
[PSCustomObject]#{ComputerName = 'ServerE'; ProcessorCount = 2; LogicalProcessor = 24 }
)
