Type Casting & Checking

Casting

Prepend a type accelerator or type name before a variable or expression.

[System.IO.FileInfo[]](gci -file)

Safe Casting & Convertion

-as acts the similar as as in C#, it tries to convert object to target type, returns $null if failed. The left operand can be:

• type name as string
• type accelerator
• type accelerator name as string

$foo -as [object]
(Get-Date) -as 'string' # convert to date string
(Get-Date) -as 'System.String'

NOTE

All objects can be casted to string.

Checking

-is and -isnot acts the same as is and is not in C#.
