Dear allAny one can help me to understand file uploading using console application step by step guideline using dotnet but please dont share link of offical sdk any moreRegards
This appears to be a follow up to your earlier thread. I'm afraid I don't have much to add to that. All of the official resources for using the Dropbox API from .NET are part of the official Dropbox .NET SDK, but it sounds like that SDK isn't suiting your needs.
(You can of course call the Dropbox API HTTPS endpoints directly, though that may be more work without the help of the SDK. For example, the /2/files/upload endpoint corresponds to the UploadAsync method in the .NET SDK.)
