PutStreamAsync() only works with streams of type System.IO.Stream #9

Open mrobraven opened 3 years ago

mrobraven commented 3 years ago

I have been playing about with image uploads and it seems that when I try and use a different type of stream, for example a MemoryStream containing a direct clone of a Stream object (as a result of using Stream.CopyTo(MemoryStream)) the upload appears to succeed but is listed on firebase as an empty file with no metadata. I tried providing the ContentType = "image/jpeg" metadata and this was applied successfully but still an empty, unreadable file was uploaded.

Also when casting between objects of base type System.IO.Stream (MemoryStream, etc....), it doesn't work either.

EG:

MemoryStream memStream = new MemoryStream(byte_data);
reference.PutStreamAsync(memStream);

Doesn't work, neither does:

MemoryStream memStream = new MemoryStream(byte_data);
Stream newStream = (Stream)memStream; // casts correctly (seen when you do newStream.Length)
reference.PutStreamAsync(newStream);

Neither does:

Stream myStream = my_stream_data; // random stream data (my test used the Media Picker functionality from Xamarin.Essentials)
MemoryStream memStream = new MemoryStream();
myStream.CopyTo(memStream); // myStream data is disposed of at this point and no longer accessible
Stream newStream = (Stream)memStream;
reference.PutStreamAsync(newStream);
