var obj = client.GetObject(bucketName, objectid);
using (var requestStream = obj.Content)
{
byte[] mbyte = new byte[(int)requestStream.Length];

            while (requestStream.Read(mbyte, 0, mbyte.Length) > 0)
            {

            }

            Response.Clear();
            Response.Buffer = true;
            Response.ContentType = "application/octet-stream";
            Response.ContentEncoding = Encoding.GetEncoding("GB2312");// Encoding.UTF8;
            Response.AddHeader("Content-Disposition", "attachment; filename=" + outputFileName);
            Response.AddHeader("Content-Length", mbyte.Length.ToString());
            Response.AddHeader("Content-Transfer-Encoding", "binary");

            Response.BinaryWrite(mbyte);
            Response.Flush();
            Response.End();

        }

使用阿里云的对象存储功能。下载文件流，然后保存成对应的文件。这段代码 txt文件保存没有问题，但是docx保存打开就显示乱码了。请路过的大神帮忙看下，是不是哪里没有设置好。有没有解决方法。
