Create variable of .NET type and input data in one line?

I want to create a variable that stores a type of array that is versatile enough to be able to accept new entries of variant types, and “powershell - Array.Add vs += - Stack Overflow” appears to describe how:

$Variable = New-Object System.Collections.Generic.List[System.Object]

However, I want to be able to add its content without adding a new line to the code:

$Variable = New-Object System.Collections.Generic.List[System.Object]
$Variable += '1','Entry2'

How?

May I ask why you want to have it on one line?

Edit:

And just BTW. Using the += operator changes the type of ne variable to System.Array

Try it …

$Variable = New-Object System.Collections.Generic.List[System.Object] 
$Variable.GetType()

outputs this:

IsPublic IsSerial Name                                     BaseType     
-------- -------- ----                                     --------     
True     True     List`1                                   System.Object

and after you run this:

$Variable += '1','Entry2'
$Variable.GetType()

it outputs this:

IsPublic IsSerial Name                                     BaseType    
-------- -------- ----                                     --------    
True     True     Object[]                                 System.Array

To add an element to a dotNet generic list you have to use the .Add() method. :wink:
