Understanding the Problem

In the example provided, you may have encountered the following error when trying to execute this line of code:

This indicates that the Add method you are trying to use cannot accept three parameters. The Add function typically supports only two arguments — the key and the value. Thus, attempting to pass a third argument results in an error.

The Objective

You desire to create a structure that resembles a table, or a dictionary, with three columns: name, status, and createdAt. The expected output should look like this:

A Simple Solution

Instead of using the Add method ineffectively, an alternative approach is to create a custom object that includes all desired properties. This solution is straightforward and effective. Here’s how to do it:

Step-by-Step Implementation

Initialize an Array: Start by creating an empty array to hold your results.

Loop Through Data: Use a ForEach-Object loop to iterate through each item in your data set ($workflowInfo).

Create Custom Objects: Inside the loop, construct a PSCustomObject for each item containing the required properties.

Store Objects in the Array: Use the += operator to add each custom object to your array.

Sample Code

Here’s the complete code implementing the above steps:

Breakdown of the Code

$checkStatuses = @(): Initializes an empty array to store the custom objects.

$workflowInfo | ForEach-Object { ... }: Loops through each object in $workflowInfo.

[PSCustomObject]@{}: Creates a new custom object with properties name, status, and createdAt.

+=: Adds the new object to the $checkStatuses array.

Conclusion

If you’re facing similar issues with your PowerShell scripts, consider these techniques to optimize how you store and manipulate data effectively!
