How to assign values to a property of an object?

PowerShell Help

I have the following variable which is returned from a function:

[DBG]: PS C:\Users\jmilano\Documents\PowerShell_Scripts\VMs>> $RawHistoryItem | get-member


   TypeName: VMware.Vim.VmMigratedEvent

Name                 MemberType Definition                                                        
----                 ---------- ----------

ToString             Method     string ToString()                                                 
ChainId              Property   int ChainId {get;set;}                                            
ChangeTag            Property   string ChangeTag {get;set;}

Dvs                  Property   VMware.Vim.DvsEventArgument Dvs {get;set;}                        
FullFormattedMessage Property   string FullFormattedMessage {get;set;}                            
Host                 Property   VMware.Vim.HostEventArgument Host {get;set;}                      
Key                  Property   int Key {get;set;}                                                
Net                  Property   VMware.Vim.NetworkEventArgument Net {get;set;}                    
SourceDatacenter     Property   VMware.Vim.DatacenterEventArgument SourceDatacenter {get;set;}    
SourceDatastore      Property   VMware.Vim.DatastoreEventArgument SourceDatastore {get;set;}      
SourceHost           Property   VMware.Vim.HostEventArgument SourceHost {get;set;}                
Template             Property   bool Template {get;set;}                                          
UserName             Property   string UserName {get;set;}                                        
Vm                   Property   VMware.Vim.VmEventArgument Vm {get;set;}

I want to assign the value of various properties of this variable to another variable using this syntax:

$GetRawHistoryAll = Get-VIEventPlus -Entity $entity -Start $start -EventType $eventTypes -Recurse:$Recurse
ForEach( $RawHistoryItem in $GetRawHistoryAll)
    {
    $Item = New-Object PSObject
    $Item | Add-Member -type NoteProperty -Name 'CreatedTime' -Value ($RawHistoryItem.CreatedTime.TolocalTime())
    $Item | Add-Member -type NoteProperty -Name 'Type' -Value  {If($RawHistoryItem.SourceDatastore.Name -eq $RawHistoryItem.Ds.Name){"vMotion"}else{"svMotion"}}
    $Item | Add-Member -type NoteProperty -Name 'UserName' -Value {if($RawHistoryItem.UserName){$RawHistoryItem.UserName}else{"System"}}
    $Item | Add-Member -type NoteProperty -Name 'VM' -Value ($RawHistoryItem.VM.Name)
    $Item | Add-Member -type NoteProperty -Name 'SrcVMHost' -Value ($RawHistoryItem.SourceHost.Name.Split('.')[0])
    $Item | Add-Member -type NoteProperty -Name 'TgtVMHost' -Value {if($RawHistoryItem.Host.Name -ne $RawHistoryItem.SourceHost.Name){$RawHistoryItem.Host.Name.Split('.')[0]}}
    $Item | Add-Member -type NoteProperty -Name 'SrcDatastore' -Value ($RawHistoryItem.SourceDatastore.Name)
    $Item | Add-Member -type NoteProperty -Name 'TgtDatastore' -Value {if($RawHistoryItem.Ds.Name -ne $RawHistoryItem.SourceDatastore.Name){If([String]::IsNullOrEmpty($RawHistoryItem.Ds.Name)){"NA"}Else{ $RawHistoryItem.Ds.Name}}}


    $history += $Item 
    }

Here is what I’m seeing on $Item after the assignments:

CreatedTime  : 2/04/2025 5:47:22 PM
Type         : If($RawHistoryItem.SourceDatastore.Name -eq $RawHistoryItem.Ds.Name){"vMotion"}else{"svMotion"}
UserName     : if($RawHistoryItem.UserName){$RawHistoryItem.UserName}else{"System"}
VM           : vCLS-9419f797-8615-401d-8034-0123456789
SrcVMHost    : MyHost05
TgtVMHost    : if($RawHistoryItem.Host.Name -ne $RawHistoryItem.SourceHost.Name){$RawHistoryItem.Host.Name.Split('.')[0]}
SrcDatastore : MyDatastore001
TgtDatastore : if($RawHistoryItem.Ds.Name -ne $RawHistoryItem.SourceDatastore.Name){If([String]::IsNullOrEmpty($RawHistoryItem.Ds.Name)){"NA"}Else{ $RawHistoryItem.Ds.Name}}

How can I evaluate the IFs in the above so that I get the values assigned to the $Item properties?

You don’t need to use Add-Member anymore. You can use a [PSCustomObject]

$GetRawHistoryAll = Get-VIEventPlus -Entity $entity -Start $start -EventType $eventTypes -Recurse:$Recurse
$history =
ForEach ( $RawHistoryItem in $GetRawHistoryAll) {
    [PSCustomObject]@{
        CreatedTime  = $RawHistoryItem.CreatedTime.TolocalTime()
        Type         = If ($RawHistoryItem.SourceDatastore.Name -eq $RawHistoryItem.Ds.Name) { "vMotion" }else { "svMotion" }
        UserName     = if ($RawHistoryItem.UserName) { $RawHistoryItem.UserName }else { "System" }
        VM           = $RawHistoryItem.VM.Name
        SrcVMHost    = $RawHistoryItem.SourceHost.Name.Split('.')[0]
        TgtVMHost    = if ($RawHistoryItem.Host.Name -ne $RawHistoryItem.SourceHost.Name) { $RawHistoryItem.Host.Name.Split('.')[0] }
        SrcDatastore = $RawHistoryItem.SourceDatastore.Name
        TgtDatastore = if ($RawHistoryItem.Ds.Name -ne $RawHistoryItem.SourceDatastore.Name) { If ([String]::IsNullOrEmpty($RawHistoryItem.Ds.Name)) { "NA" }Else { $RawHistoryItem.Ds.Name } }
    }
}
