Response.Clear();
Response.AppendHeader("Content-Disposition", "attachment;filename=" + Server.UrlEncode(filename));
Response.ContentEncoding = System.Text.Encoding.Default;
Response.ContentType = dr["doctype"].ToString();
Response.Charset = "gb2312";
Response.BinaryWrite((byte[])dr["doc"]);
Response.Flush();
Response.Close();
