Custom objects (PSCustomObject) in PowerShell - Mini Project: Build & Apply

Create and Use Custom Objects (PSCustomObject) in PowerShell

📖 Scenario: You work in a small company where you need to organize employee information clearly. You want to create a simple list of employees with their names and ages using PowerShell custom objects.

🎯 Goal: Build a PowerShell script that creates custom objects for employees, adds a filter condition, and then displays the filtered list.

📋 What You'll Learn

Create a list of custom objects with exact employee names and ages

Add a variable to set the minimum age for filtering

Use a loop or pipeline to filter employees older than the minimum age

Print the filtered list of employees

💡 Why This Matters

🌍 Real World

Knowing how to create and manipulate custom objects in PowerShell is essential for system administrators and automation engineers to handle complex data easily.

1

Create a list of employee custom objects

Create a variable called employees that holds an array of three custom objects. Each object must have two properties: Name and Age. Use these exact entries: Name = 'Alice', Age = 28, Name = 'Bob', Age = 34, and Name = 'Charlie', Age = 22. Use [PSCustomObject] to create each object.

PowerShell

# Create the employees array with three PSCustomObject entries
# Your code here

Need a hint?

Use @( ... ) to create an array and [PSCustomObject]@{} to create each object with properties.

2

Set a minimum age filter

Create a variable called minAge and set it to 25. This will be used to filter employees older than this age.

PowerShell

$employees = @(
    [PSCustomObject]@{Name='Alice'; Age=28},
    [PSCustomObject]@{Name='Bob'; Age=34},
    [PSCustomObject]@{Name='Charlie'; Age=22}
)
# Create minAge variable and set it to 25
# Your code here

Need a hint?

Just create a simple variable $minAge and assign the number 25.

3

Filter employees older than the minimum age

Create a variable called filteredEmployees that contains only the employees from $employees whose Age is greater than $minAge. Use the Where-Object cmdlet with a script block that compares $_ .Age to $minAge.

PowerShell

$employees = @(
    [PSCustomObject]@{Name='Alice'; Age=28},
    [PSCustomObject]@{Name='Bob'; Age=34},
    [PSCustomObject]@{Name='Charlie'; Age=22}
)

$minAge = 25

# Filter employees older than minAge into filteredEmployees
# Your code here

Need a hint?

Use the pipeline | and Where-Object { $_.Age -gt $minAge } to filter.

4

Display the filtered employees

Use Write-Output to print the $filteredEmployees variable so you can see the filtered list of employees.

PowerShell

$employees = @(
    [PSCustomObject]@{Name='Alice'; Age=28},
    [PSCustomObject]@{Name='Bob'; Age=34},
    [PSCustomObject]@{Name='Charlie'; Age=22}
)

$minAge = 25

$filteredEmployees = $employees | Where-Object { $_.Age -gt $minAge }

# Print the filteredEmployees
# Your code here

Need a hint?

Use Write-Output $filteredEmployees to show the filtered list.
