I have read many posts that list why you can't do this task, but I cannot believe that the online environment is that restrictive. What I am trying to do is use C# and/or web service to upload potentially thousands of files into a SharePoint library. I have already written an event handler that executes when a file is added but right now I am restricted to uploaing 100 files t a time via the GUI.
Other posts I have read state restrictions on http post, web services and other options. I have sen the CSOM mentioned as a possible solution but cannot get past the authentication issue with Sharepoint online.
Any ideas on how to get around these issues?
Thanks,
Gary
