Using existing static classes

Creating new GUID instantly

Use existing .NET classes instantly with PowerShell by using [class]::Method(args):

PS C:\> [guid]::NewGuid()

Guid
----
8874a185-64be-43ed-a64c-d2fe4b6e31bc

Similarly, in PowerShell 5+ you may use the New-Guid cmdlet:

PS C:\> New-Guid

Guid
----
8874a185-64be-43ed-a64c-d2fe4b6e31bc

To get the GUID as a [String] only, referenced the .Guid property:

[guid]::NewGuid().Guid

Using the .Net Math Class

You can use the .Net Math class to do calculations ([System.Math])

If you want to know which methods are available you can use:

[System.Math] | Get-Member -Static -MemberType Methods

Here are some examples how to use the Math class:

PS C:\> [System.Math]::Floor(9.42)
9
PS C:\> [System.Math]::Ceiling(9.42)
10
PS C:\> [System.Math]::Pow(4,3)
64
PS C:\> [System.Math]::Sqrt(49)
7

Adding types

By Assembly Name, add library

Add-Type -AssemblyName "System.Math"

or by file path:

Add-Type -Path "D:\Libs\CustomMath.dll"

To Use added type:

[CustomMath.NameSpace]::Method(param1, $variableParam, [int]castMeAsIntParam)
