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：
- C# code
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(); ------解决方案--------------------------------------------------------
改下 System.Text.Encoding.UTF8这个看看
- C# code
