Shouldn't reading a stream, end it?

Why reading Response.Content.ReadAsStreamAsync() doesn't prevent writing output to the client?



Summary: I have an ActionFilter in an ASP.NET WebAPI 2 application, which I'm reading the entire output-stream in ActionExecuted event. This is the sample code:



var content = actionExecutedContext.Response.Content.ReadAsStreamAsync().Result;
byte buffer = new byte[content.Length];
content.Read(buffer, 0, (int)content.Length);


What I'm expecting after that, is an empty-output, but the entire output is going to the client after all. What am I missing here? Shouldn't reading a stream, end it?

          Unfortunately it doesn't empty the response after calling that method, it just serializes the response and returns a Stream that represents the serialized content (see HttpContent.ReadAsStreamAsync Method)



          If you want to clear the response, you could try to set the value of the response's Content property to a new instance of one of the classes derived from HttpContent.



          Hope it helps!
