PowerShell - Working with Objects

What will this code output?

$obj = New-Object PSObject
Add-Member -InputObject $obj -MemberType NoteProperty -Name Number -Value 10
Add-Member -InputObject $obj -MemberType NoteProperty -Name Number -Value 20 -Force
$obj.Number

A10

BNull

CError: Property already exists

D20

Step-by-Step Solution

Solution:

Step 1: Add NoteProperty 'Number' with value 10
The first Add-Member adds Number=10 to $obj.
Step 2: Add NoteProperty 'Number' again with value 20 using -Force
The -Force parameter overwrites the existing property with the new value 20.
Step 3: Access $obj.Number
Since the property was overwritten, $obj.Number returns 20.
Final Answer:
20 -> Option D
Quick Check:
-Force overwrites property = 20 [OK]

Quick Trick: Use -Force to overwrite existing properties [OK]

Common Mistakes:

Expecting error on duplicate property
Ignoring -Force effect
