I have an simple proposal for the API, new method named: Session.CompareDirectories(...) Since adding to SynchronizeDirectories is not a backwards compatible, so creating a new method is probably good idea.

It's result API could be similar as the SynchronizeResult maybe CompareResult but it would allow to commit each change one by one.

Thanks for your post.

Issue 885 – Synchronization preview in scripting

Hello!

I'm trying to use Session.SynchronizeDirectories but it's missing a preview flag.

How can I do preview using .NET API? I need to first synchronize using SynchronizationMode.Both but I need to see the changes first before I let it to proceed to do the real thing, hence I need preview first.

Thanks

Edit: I found this: https://github.com/winscp/winscp/blob/5.13/dotnet/Session.cs#L908
Maybe just adding a preview bool switch there will do? I can then check the SynchronizationResult and commit the changes manually by iterating the preview result list.

Edit2: I tried in my local fork of WinSCP dotnet DLL but it probably requires a bigger change than just a flag.
