Working on a simple helper function in PowerShell that takes a couple of parameters and creates a custom Enumerable object and outputs that object to the pipeline. The problem I am having is that PowerShell is always outputting a System.Array that contains the objects that are enumerated by my custom Enumerable object. How can I keep PowerShell from unpacking the Enumerable object?

What is @() in PowerShell Script? In PowerShell, the array subexpression operator “@()” is used to create an array. To do that, the array sub-expression operator takes the statements within the parentheses and produces the array of objects depending upon the statements specified in it.
delete element It's not easy to delete array element in PowerShell. Array data structure is not designed to change size. Instead of delete, just replace the value with $null .
Use += to Add Objects to an Array of Objects in PowerShell The Plus Equals += is used to add items to an array. Every time you use it, it duplicates and creates a new array. You can use the += to add objects to an array of objects in PowerShell.
Try to change the line 46 from
$row
to
, $row
EDIT: as Johannes correctly pointed out, the unary operator comma creates an array with one member.
