SSIS 2012 TransferOptions.FileMask causing exception has been thrown by the target of an invocation

Everything works great until I add the filemask...Once I do, I get an exception has been thrown by the target of an invocation...Could you please tell me what I'm doing wrong?

TransferOptions lTransferOptions = new TransferOptions();
lTransferOptions.FileMask = "LOR*.zip" ;
TransferOperationResult lTransferResult = lSession.GetFiles(remotePath, localPath, false, lTransferOptions);
lTransferResult.Check();

Thank you

The exception must have an inner exception with more details.

Or attach a session log file.

Thank you for the reply. Actually this filemask now works (some weirdness going on there). I now need to add an exclusion filemask

Would this be the correct way to exclude any files with the name of RSCH-*.zip?

TransferOptions lTransferOptions = new TransferOptions();
lTransferOptions = | "RSCH-*.zip";
TransferOperationResult lTransferResult = lSession.GetFiles(remotePath, localPath, false, lTransferOptions);
lTransferResult.Check();

Thanks much,
Lorie

This is the correct way:

lTransferOptions = "| RSCH-*.zip";
