ASP.NET (C#) Question
Returning File() returns more bytes
Consider the following code:
//get bytes
var query = await _storage.Get(attachment.Id, General.ContainerType.Uploads);
//just for the sake of debugging
var mem = new MemoryStream(query);
//return the uploaded file
return File(mem, MimeTypesMap.GetMimeType(attachment.FileName), attachment.FileName);
After uploading a .jpg image of 67kb and then downloading it with this method, the returned image is 107 kb. I have checked whether the bytes are stored and retrieved correctly and they indeed are constistent with what I have uploaded. If I upload a text file and return it the content and the size is correct.
I assume File() does some magic, but I can't figure out why and what?
