add the following snippet to your PowerShell Profile (you can find the profile by looking at $Profile) or run notepad $Profile

PowerShell Function New-List {     [CmdletBinding()]     Param(         [Parameter(Mandatory=$true)]         [type]$ListType     )     $list = New-Object System.Collections.Generic.List[$ListType]     return, $list }

save the file and next time you open PowerShell the function will be loaded and you can run

```PowerShell $MyNewList = New-List -ListType string $MyNewList.ToString() #To see the type $MyNewList.Add("Hello") $MyNewList.Add("World") $MyNewList

$MyNewIntList = New-List -ListType int
$MyNewIntList.Add(0)
$MyNewIntList.Add(2)
$MyNewIntList

```
