Types
A type is used to represent the generalized functionality of an object. This description is vague, but a .NET type can be used to describe anything; it is hard to be more specific. To use this book as an example, it could have several types, including the following:
PowerShellBook
TextBook
Book
Each of these types describes how an object can behave. The type does not describe how this book came to be, or whether it will do anything (on its own) to help create one.
In PowerShell, types are written between square brackets. The [System.AppDomain]
and [System.Management.Automation.PowerShell]
statements, used when discussing previous assemblies, are types.
The type of an object can be revealed by the Get-Member
command (the following output is truncated):
PS> 1 | Get-Member
