Types


You need to learn that PowerShell is an object-oriented programming or scripting language, and it is based on .NET. What does that actually mean? Every parameter and every return value are of a specific type. And because PowerShell is based on .NET, these are .NET types. There are different ways to retrieve the type of an object:

"String"
[System.DateTime]"24/08/2018"
"String".GetType()

([System.DateTime]"24/08/2018").GetType()
Get-Member -InputObject "String"

This differs from most of the other scripting languages, where you primarily pass and retrieve strings, and makes PowerShell a scripting language with a lot of similarities to full stack developing languages. In the following overview, you will see the commonly used types:

# sequence of UTF-16 code units.
[String]
# character as a UTF-16 code unit.
[Char]
# 8-bit unsigned integer.
[Byte]

# 32-bit signed integer
[Int]
#64-bit signed integer
[Long]
# 128-bit decimal value
[Decimal]
# Single-precision 32-bit floating point number...
