Comparing 2 variables that has got set of arrays as it's values

Question

Hi All, I have 2 variables $a and $b, both are set of arrays, but $a has values of 3 column data let’s say name, id, salary, and $b just 1 array of data. Now, I want to run a command to find out whether $a contains $b and if it contains i want to know the ID of the matching Name, how is that possible?

Thanks, Niru

Like this:

$a = @("A",1,123),@("C",3,175),@("D",4,136) # name, id, salary
$b = "A","D"                                # name
ForEach ($employee in $a){
    if ($b -contains $employee[0]){
        Write-Host "Found $($employee[0]) with ID $($employee[1])"
    }
}
