If you're using .NET, we recommend using the official Dropbox API v2 .NET SDK:
https://github.com/dropbox/dropbox-sdk-dotnet
There's a guide there for getting started.
For your use case in particular, you can list files in any folder using listFolder:

You can check the returned FileMetadata.ContentHash and compare with your local copy:

You can find information on computing the content hash value for your local files here:
