Cannot find the result of a Get method inside IOwinContext object

Question

I have an OwinMiddleware with an Invoke method looking kind of like this:

public override async Task Invoke(IOwinContext context)
{
    ...
    //The next line launches the execution of the Get method of a controller
    await Next.Invoke(context);
    //Now context.Response should contain "myvalue" right?
    ...
}

The Invoke method invokes a Get method, located inside a controller, which looks kind of like this:

[HttpGet]
public IHttpActionResult Get(some params...)
{
    ...
    return "myvalue";
    ...
}

After the execution of the Get method, the program goes back to the Invoke method of my middleware. I think that the response of the Get method, namely myvalue, should be contained inside context.Response, but I don't know where precisely, because it's full of things.

Actualy response is a stream and You need to do this to get response back in orignal form

 try{
      var stream = context.Response.Body;
      var buffer = new MemoryStream();
      context.Response.Body = buffer;
      await _next.Invoke(environment);
      buffer.Seek(0, SeekOrigin.Begin);
      var reader = new StreamReader(buffer);
      // Here you will get you response body like this
      string responseBody = reader.ReadToEndAsync().Result;
      // Then you again need to set the position to 0 for other layers
      context.Response.Body.Position = 0;
      buffer.Seek(0, SeekOrigin.Begin);
      await buffer.CopyToAsync(stream);
    }
    catch(Exception ex)
    {

    }
