Join or Concatenate Two Powershell Variables

Question

Trying to concatenate two variables with an array inside them.

First variable contains:

 PS C:\WINDOWS\system32> $svcStatus

    Response Status
    -------- ------
         200 OK

Second variable contains:

PS C:\WINDOWS\system32> $svcCall 

displayName     serviceTypeUrl                                                                                port servicePort
-----------     --------------                                                                                ---- -----------

When they are joined:

PS C:\WINDOWS\system32>$mansvcApp = -join $svcStatus, $svcCall
$mansvcApp 
@{Response=200; Status=OK}

displayName     serviceTypeUrl                                                                                port servicePort
-----------     --------------                                                                                ---- -----------

How can I get it to look like this:

displayName     serviceTypeUrl                                          port servicePort Response status
-----------     --------------                                          ---- ----------- -------- ------
AutnTestService http://demo1.blah.co.uk/blah/api/v2/service_types/0310b 9000    9002        200     OK

-join should be used to join elements of an array into a string like this: $MyArray -join "," — Dave Sexton

One way you could do it is like this:

$svcStatus | Add-Member -MemberType NoteProperty -Name displayname -Value $svcCall.displayname
$svcStatus | Add-Member -MemberType NoteProperty -Name serviceTypeUrl -Value $svcCall.serviceTypeUrl

If you have several columns to add and you don't want to a lot of typing then you could use a loop to do it like so:

$svcCall | Get-Member -MemberType NoteProperty | % {
    $n = $_.name
    $svcStatus | Add-Member -MemberType NoteProperty -Name $n -Value $svcCall."$n"
}

Brilliant. Just what I was looking for. For better understanding why did you append $svcCall.displayname at the end.

-Name displayname -Value $svcCall.displayname indicates to me that you are appending the ending entries from svcCall to svcStatus.displayname. Shouldn't -Name be reflective of what the name of one of the tables within svcCall should be.
