Ionic.Zip 中打包下载后的中文文件名出现乱码问题

[matusharen]

求救，很急。。。最近做个项目，需要从打包下载文件到客户端。。。可是下载下来的文件中有如果是中文命名的就会出现？？？？的字样，

我的源代码：

  
        Teacher tea = (Teacher)Session["teacher"];
        string a = tea.teach_id;
        string filepath = Server.MapPath("~/");
        //Directory.CreateDirectory(filepath+"download");
        ZipFile zip = new ZipFile(filepath+"download.zip");
        //zip.AddDirectory(filepath+"download");
        
        for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
        {
            CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
         
            if (cbox.Checked == true)
            {
                 SQL mysql = new SQL();
                 string str = "select * from StuCourseFile where teach_id = '" + a + "'";
                 DataTable table = mysql.mytable(str);
                 string FilePath = table.Rows[i]["StuFilePath"].ToString();
                 string FileName = table.Rows[i]["StuFileName"].ToString();
               
                 zip.AddFile(FilePath+FileName,"");
                
            }
                 
        }
        Response.Clear();
        Response.ContentType = "application/zip";
        Response.AddHeader("content-disposition", "attachment;filename=" + HttpUtility.UrlEncode("reportdownload.zip", System.Text.Encoding.UTF8));
        zip.Save(Response.OutputStream);
        Response.End();
