Merge similar PSObjects from an array-CodePudding

I have the following array with similar PSObjects :

PS C:\Test\$events

total events
----- ------

every object from $events.events has similar properties, because they're coming from an API query with pagination, with one query page being a line in the array.

My question : how can I merge all objects from this list as a single PSObject, and keeping the exact same properties ?

CodePudding user response：

I'm guessing you're looking to group all objects by the Total property and create a new unified object that contains all objects in Events.

If my assumption is right, you can group them using Group-Object and then create a new instance:

$newObject = $events | Group-Object Total | ForEach-Object {
    [pscustomobject]@{
        Total  = [Linq.Enumerable]::Sum([int[]] $_.Group.Total)
        Events = $_.Group.Events
    }
}
