Mastering Windows PowerShell Scripting - Third Edition

Accessing properties

Properties of an object in PowerShell may be accessed by writing the property name after a period. For example, the Name property of the current PowerShell process may be accessed by using the following code:

$process = Get-Process -Id $PID 
$process.Name

(Get-Process -Id $PID).Name 

Properties of an object are objects themselves. For example, the StartTime property of a process is a DateTime object. We may access the DayOfWeek property by using the following code:

$process = Get-Process -Id $PID 
$process.StartTime.DayOfWeek
