Call the properties/methods on the Piped Object

I am trying to understand how to pipe | an object and call the properties or methods on that.

Ex:
$a = Get-Item Registry::HKLM\SOFTWARE\WOW6432Node\Microsoft\Test\abc\
$a.GetSomething()  //calls the method
(Get-Item Registry::HKLM\SOFTWARE\WOW6432Node\Microsoft\Test\abc\).GetSomething() //calls the method

Can I pipe the output of the Get-Item and invoke properties/methods on it?

Get-Item Registry::HKLM\SOFTWARE\WOW6432Node\Microsoft\Test\abc\ | call GetSomething()
Solution

  • The short answer is no. You can't call a method like this using Pipeline. But you can surround your Get-Item invoke in parentheses and invoke it:

    (Get-Item Registry::HKLM\SOFTWARE\WOW6432Node\Microsoft\Test\abc\).GetSomething()

    If you don't want that, you could abuse the Select-Object cmdlet:

    Get-Item Registry::HKLM\SOFTWARE\WOW6432Node\Microsoft\Test\abc\  | select { $_.GetSomething() }
