Powershell and combining different object arrays

Hello EE,

I wish to create a script whereby it does 3 core tasks

1-  $getapplicationevents = get-eventlog -logname application

2-   $getsystemevents = get-eventlog -logname system

3-  $errorlogs = import-csv "c:\logs\logs.csv"

At this point i wish to combine certain member properties of each of the previous objects into a new "master object" with the goal of inserting into a database table or export to csv. All of the 3 objects would have a similar property the "host's name" . This would be similar concept to a primary key

My question is around the combining of certain member properties ;

Using $masterobject as the target for combining, with $getapplicationevents.message, $getsystemevents.message and $errorlogs.message in one array of objects ,$masterobject .The understanding is i would need to create the $masterobject and then use the add-member command but unsure of the structure from here ..
