asp.net – Chrome浏览器不显示HTTP处理程序生成的图像

<img width="50" height="50" src="http://portal/Service/GetFile.asxh?id=123&inline=true">

由于某些原因,Chrome之外的所有浏览器(例如IE6 / 7/8,Firefox,Opera,Safari)都显示出一切正常,但是对于这些图像,Chrome会显示“图像破坏”图标.如果我选择“在新选项卡中打开图像”,则图像显示得很好.

编辑我以为我已经解决了这个问题,但显然是与Fiddler打开了一样.

我在代码中留下了context.Response =“utf-8”,但删除它没有任何区别.

                    byte[] buff = new byte[BuffSize];
                    using (var stream = repository.GetFileContentsAsStream(file.ContentId))
                    {
                        int bytesRead;
                        do
                        {
                            bytesRead = stream.Read(buff,BuffSize);
                            if (bytesRead > 0)
                            {
                                context.Response.OutputStream.Write(buff,bytesRead);
                            }
                        } while (bytesRead > 0);
                    }

                    context.Response.Flush();
                    context.Response.Close();
