Error handling within Foreach-object Parallel block - Powershell 7

问题

What would be the best way to capture error within below Foreach-Object Parallel block as there would be three separate threads/runspaces running and executing code written in the block and multiple errors/exception can occurs at the same time? Would it be possible to capture all the errors in a list/variable and show at the end of the execution of the script?

1..3 | ForEach-Object -ThrottleLimit 3 -Parallel  {
            #Some code here that throws error                
}

回答1:

The -ErrorVariable param will give you an arraylist of ErrorRecords at the end:

1..3 | ForEach-Object -ThrottleLimit 3 -Parallel {
    throw "Item $_ Error"
} -ErrorVariable allErrors
