            using (var fileStream = new FileStream(System.Web.Hosting.HostingEnvironment.MapPath("~/Content/Reports/abaw.bmp"), FileMode.Create, FileAccess.Write))
            {
                stream.CopyTo(fileStream);
            }


            return stream;
        }

Hello,

Please instead of stream.CopyTo() method use the stream.WriteTo() method.
