.Net SDK on UWP download stream sends empty buffers on read
Hi Dropbox dev community! We're having a bit of a problem with the .Net SDK on our UWP app : we're using response.GetContentAsStreamAsync() after getting the path of a file on a dropbox account, ...
We looked into this, and we believe the issue here is due to this possible behavior from Stream.Read:
Return Value Type: System.Int32 The total number of bytes read into the buffer. This can be less than the number of bytes requested if that many bytes are not currently available, or zero (0) if the end of the stream has been reached.
That means that byteReadLength in the code snippet here won't always necessarilly be a whole 4 MB. The being the case, it looks like you'll need to make two changes:
- when you write the data to the file, only write as much as byteReadLength
- when you increment your downloadProgress, only add as much as byteReadLength

it works much better indeed! Thank you!
