PowerShell by default copies any object by reference. Any changes made to the copy is also made to the original as they are the same object. This functions makes a copy of the original object by value, leaving the original object unchanged when you modify the copy. NB: The copy is made using serialization which may adversely affect some object types. .INPUTS [PSObject] .OUTPUTS [PSObject] .EXAMPLE $NewObject = Copy-PSObject $Object Creates a new object with the same value as $Object. .EXAMPLE $NewObject = Copy-PSObject -InputObject $Object Creates a new object with the same value as $Object. .EXAMPLE $Object | $NewObject = Copy-PSObject Creates a new object with the same value as $Object. .NOTES NAME: Copy-PSObject .LINK #> [CmdLetBinding()] Param ( [Parameter( Mandatory = $true, ValueFromPipeLine = $true, Position = 0 )] [PSObject] $InputObject ) begin { # Enable modern -Debug behavior if ($PSCmdlet.MyInvocation.BoundParameters['Debug'].IsPresent) { $DebugPreference = 'Continue' } Write-Debug ('{0}: Begin of function' -F $MyInvocation.MyCommand.Name) # Setup objects for use $Stream = New-Object System.IO.MemoryStream $Binary = New-Object System.Runtime.Serialization.Formatters.Binary.BinaryFormatter } Process { Write-Verbose ('{0}: Making a copy of a(n) {1} object' -F $MyInvocation.MyCommand.Name, $InputObject.GetType().FullName) # Serialize data using BinaryFormatter $Binary.Serialize($Stream, $InputObject) # Reset Stream position $Stream.Position = 0 } end { # Return a copy of the original object $Binary.Deserialize($Stream) # Close the stream $Stream.Close() Write-Debug ('{0}: End of function' -F $MyInvocation.MyCommand.Name) } } |
