Error while copying content to a stream in C#
Hi, I encountered the problem "Error while copying content to a stream" when executing the above code. Is there any way to fix it? try { var chunkSize = 16 * 1024 * 1024; ...
Rephoto If you wish to optimize your upload process, please refer to the Performance Guide: https://developers.dropbox.com/dbx-performance-guide
That offers some ways you may be able to improve your effective overall upload speed. For example, there are batching and parallelization features you can use.
For instance, as Здравко noted, the default upload session type is "sequential", but you can use "concurrent" to upload file pieces in parallel. That would require you to make some more changes to your code to properly send those pieces in parallel though.

Thanks for sharing the additional information. It looks like this is related to you trying to start multiple tasks within the loop without awaiting them, leading to the stream being closed (due to the iteration continuing and moving on to the next piece of the file) before it can be used.
Exactly how you structure your code/tasks is up to you, but to get this working I suggest awaiting each append task, instead of using tasks.Add and Task.WhenAll.
Hi Rephoto,
When you're starting upload session, you use the default type - sequential session, but when actual upload gets on you're trying concurrent upload. Decide what you want actually.
Hope this gives direction.
