Add values to PS object from other PS command - powershell

Question

I created the following object:
$PSOhash = #{
ConnectedNode = $ConnectedNode
ConnectedNodeDeviceNumber = $ConnectedNodeDeviceNumber
Serialnumber = $Serialnumber
ProductId = $ProductId
}
$ClusterNodeSSDs = New-Object PSObject -Property $PSOhash
and want to add values from the following command into it:
$SSDModel = "xyz123"
$ClusterNode = "Node1"
gwmi -Namespace root\wmi ClusPortDeviceInformation| select ConnectedNode,ConnectedNodeDeviceNumber, Serialnumber, ProductId | sort ConnectedNodeDeviceNumber | where {($_.ConnectedNode -eq $ClusterNode) -and ($_.ProductId -match "$SSDModel")}
which returns the proper informations, but need them as properties in the object for further processing.

Answer 1

If you want to add a set of property-value pairs to an already existing PSObject ($MyObject in this example) that currently does not have those properties, you can use the Add-Member command for this:
$PSOhash = #{
ConnectedNode = $ConnectedNode
ConnectedNodeDeviceNumber = $ConnectedNodeDeviceNumber
Serialnumber = $Serialnumber
ProductId = $ProductId
}
$MyObject = $MyObject | Add-Member -NotePropertyMembers $PSOHash
Explanation:
The -NotePropertyMembers parameter allows you do add a hash table of property-value pairs to a custom object.
Optionally, you can use a combination of Add-Member's -NotePropertyValue and -NotePropertyName to add properties one at a time.
If you want to update one object's property values with property values (same property names) from another object, you can just use direct assignment and the member access operator (.).
$SSDModel = "xyz123"
$ClusterNode = "Node1"
$WmiObjects = Get-WmiObject -Namespace root\wmi ClusPortDeviceInformation |
Select-Object ConnectedNode,ConnectedNodeDeviceNumber, Serialnumber, ProductId |
Sort-Object ConnectedNodeDeviceNumber |
where {($_.ConnectedNode -eq $ClusterNode) -and ($_.ProductId -match "$SSDModel")}
$ClusterNodeSSDs = foreach ($WmiObject in $WmiObjects) {
$PSOhash = #{
ConnectedNode = $WmiObject.ConnectedNode
ConnectedNodeDeviceNumber = $WmiObject.ConnectedNodeDeviceNumber
Serialnumber = $WmiObject.Serialnumber
ProductId = $WmiObject.ProductId
}
[pscustomobject]$PSOhash
}
Explanation:
Note the use of the foreach loop here because the Get-WmiObject will likely return a collection. So you will need to iterate all of them to create custom objects. However, it just seems that you can just use the Get-WmiObject | Select-Object output to perform the same thing.
