下载文件名称长度限制

昨天测试了下载文家名称的长度，可是文件名称过长的话（具体是超过17个）就会出现乱码。
由于系统的需求文件名称是肯定会超过17个的
不知道那位高人指点下了

Answer 2

文件长度超过17没问题，应该是代码问题
  string path = Server.MapPath("~/") +"";
 Response.AppendHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode(obj.Name, System.Text.Encoding.GetEncoding("utf-8"))  + "." + obj.AttachmentExt);//HttpUtility.UrlEncode                    if (File.Exists(path))
                    {
                        Response.ContentType = "application/octet-stream";
                        Response.WriteFile("" + path + "");
                    }
                    Response.End();

Answer 3

对文件名字进行UTF-8编码
Response.AppendHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode("UTF-8","文件名");

Answer 4

   Response.Clear();
            Response.ClearHeaders();
            Response.Buffer = false;
            string FileName = System.Web.HttpUtility.UrlEncode(System.Text.Encoding.UTF8.GetBytes(_lf.filename));
            Response.ContentType = "application/octet-stream";
            Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(_lf.filename, System.Text.Encoding.GetEncoding("utf-8")));
            Response.WriteFile(Server.MapPath("~/LawFile/") + _lf.savename);
            Response.Flush();
