Test Upload success! Download times wrong:

Because the download method is as follows:

Context. Response.appendheader ("Content-length", filesize.tostring ()); Context. Response.CacheControl = HttpCacheability.Public.ToString (); Context. Response.Cache.AppendCacheExtension ("max-age=" + 365 * 24 * 60 * 60); Context. Response.Cache.SetExpires (DateTime.Now.AddYears (1)); Context. Response.appendheader ("ETag", "never_modify"); Context. Response.Cache.SetETag ("never_modify"); Context. Response.Cache.SetLastModified (DateTime.Now.AddMinutes (-1)); Context. Response.TransmitFile (FilePath);

Modify the Download mode:

FileStream FS =newfilestream (FilePath, FileMode.Open);     byte[] bytes =newbyte[(int) fs. Length];     fs. Read (bytes, 0, bytes. Length);     fs. Close ();     response.contenttype = "Application/octet-stream";     //notifies the browser to download the file instead of opening the     respons E.addheader ("Content-disposition", "attachment filename=" + httputility.urlencode (filename, SYSTEM.TEXT.ENCODING.UTF8));     context. Response.BinaryWrite (bytes);     context. Response.Flush ();     context. Response.End ();
