Variables in PowerShell#

Variables in [[PowerShell]] are specified by putting a dollar sign ($) in front of their name such as $apples, $oranges, etc.

How-To: Create a Variable 
$var = val

It is important to note that all PowerShell variables are .NET objects and we can call methods on them via the $var.method() syntax.

Type Casting#

Variables (and literal values, too) can be converted between different types in PowerShell by prepending them with the cast operator [<type>]- for example, [IPAddress]"10.10.11.29", [float]$apples.

If the value does not represent a valid object of the type <type>, then PowerShell will return an error.
