#PSTip Invoking methods with New-Object

Note: This tip requires PowerShell 2.0 or above.

Starting with PowerShell 2.0 we can create new objects and set property values with the Property parameter. For instance, launch MS Word and set its visibility.

New-Object -ComObject Word.Application -Property @{Visible=$true}

Did you know that you can also invoke objects methods? The next example creates a new instance of IE and navigates to a website.

$property = @{Visible=$true; Navigate2='http://PowerShellMagazine.com'}
New-Object -ComObject InternetExplorer.Application -Property $property

In the following example we create a new ArrayList object and invoke the AddRange method to create 10 elements with corresponding values from 1 to 10.

New-Object System.Collections.ArrayList -Property @{AddRange = 1..10}
