Leveraging powershell to compare two files and email me if a difference has been detected

I am using PowerShell to export a list of users who are a member of the administrators group in a text file. I am then using Compare-Object to look for the differences. I am looking to automate this process and email me if a difference is found. I am able to compare the two files and send an email, but I realize I don't know how to add the output of the compare to the email.

Maybe this is what you're looking for:

$changedEntries = Compare-Object (gc adminreport.txt) (gc adminreport2.txt) | ?{$_.SideIndicator -eq "<="}  | select -expandproperty inputobject
Write-Host "Changed entries: $changedEntries"
if ($changedEntries) {
    $joinedChangedEntries = 
    send-mailmessage smtpserver mail .mydomaincom -To [email protected] -From [email protected] -Subject 'Admin member changed' -Body 
}

UPDATE:

I tested above code with simple int-arrays.

$a = 1..4
$b = 4..8
$changedEntries = Compare-Object $a $b | ?{$_.SideIndicator -eq "<="}  | select -ExpandProperty inputobject
$joinedEntries = $changedEntries -join ","
if ($changedEntries) { write-host "Found changed entries: $joinedEntries" }
$joinedEntries.GetType()

 IsPublic IsSerial Name                                     BaseType
 -------- -------- ----                                     --------
 True     True     String                                   System.Object

So the code skeleton is the same as posted above.
