Efficiently Create a Series in System.Object with PowerShell

Creating a series of properties in a System.Object using PowerShell can often feel laborious if done manually. Many developers find themselves typing out each property one by one, which can be both time-consuming and error-prone. If you've ever wondered if there’s a more effective way to do this, you're in the right place! In this post, we’ll walk through a streamlined method for generating a property series using PSCustomObject in PowerShell.

The Problem

To illustrate the challenge, let's take a closer look at an example. You might typically set up your series like this:

While this approach works, it requires a lot of typing, especially for long ranges. So, how can we simplify this process?

The Solution

The good news is that there are more efficient methods to create a series in System.Object. Below are a couple of effective approaches:

Method 1: Using an Ordered Dictionary

Create an Ordered Dictionary: Start by creating an ordered dictionary where you'll define the initial property, "Course".

Generate the Range of Integers: Use the .. range operator to generate integers from 5 to 35, adding empty values to the dictionary for each integer.

Convert to PSCustomObject: Finally, convert the ordered dictionary to a PSCustomObject.

Method 2: Using Select-Object with Range Operator

Alternatively, you can also use the Select-Object cmdlet combined with the range operator to define your properties in a more compact way. Here’s how you can do it:

Summary

Both of these methods significantly reduce the amount of code you need to write when creating a series of properties in a System.Object using PowerShell. Choosing the right method depends on your specific use case, but both are great solutions to simplify your PowerShell scripting.

By using ordered dictionaries or the Select-Object approach with the range operator, you can create more maintainable and readable code without the hassle of manual entry.

Now you have a quick way to create those series without typing them all out! Happy scripting!
