Are streams disposed in NancyFx when using StreamResponse()?
Using a streamWriter to write to the stream, I can't dispose of it without closing the stream I want to send out. And the way I see it, I can't dispose of the stream manually either since I effectively left the method at the return.
This code works:
// Open a stream and write to it with streamReader
Stream memStream = new MemoryStream();
StreamWriter memWriter = new StreamWriter(memStream, Encoding.UTF8);
memWriter.Write(someStringText);
memWriter.Flush();
memStream.Position = 0;
// Add stream to the respose which should get downloaded
var response = new StreamResponse(() => memStream, MimeTypes.GetMimeType(contentType));
return response.AsAttachment(someFileName);
Do I need to worry about the stream lingering on until the garbage collector comes along or do it get disposed correctly by the StreamResponse?
According to StreamResponse.cs, StreamResponse.Dispose() disposes of the stream returned by the Func<Stream>, and Nancy handles disposing the Response at the end of the NancyContext.
As for disposing of StreamWriter without affecting the underlying stream, see this answer.
