How to find how many files were put/get in a session

I am trying to report via email how many files were put/get in a session. I am using powershell .NET assembly automation.
Thanks

Session.GetFiles and Session.PutFiles return TransferOperationResult.

Use TransferOperationResult.Transfers.Count to learn number of transferred files.
