Question

在asp.net的页面中，点击下载按钮时下载文件并以打包的形式的代码  怎么写啊？？

Answer 1

string fileName = "";//客户端保存的文件名
        string filePath = Server.MapPath("App_Data/进销存.doc");//路径        //以字符流的形式下载文件
        FileStream fs = new FileStream(filePath, FileMode.Open);
        byte[] bytes = new byte[(int)fs.Length];
        fs.Read(bytes, 0, bytes.Length);
        fs.Close();
        Response.ContentType = "application/octet-stream";
        //通知浏览器下载文件而不是打开
        Response.AddHeader("Content-Disposition", "attachment;   filename=" + HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8));
        Response.BinaryWrite(bytes);
        Response.Flush();
        Response.End(); 

Answer 2

导入Io命名空间
        string filename = "文件夹/"+name;
        if (filename != "")
        {
            string path = Server.MapPath(filename);
            FileInfo file = new FileInfo(path);
            if (file.Exists)
            {
                Response.Clear();
                Response.AddHeader("Content-Disposition", "attachment;filename=" + Server.UrlEncode(name));
                Response.AddHeader("Content-Length", file.Length.ToString());
                Response.ContentType = "application/octet-stream; charset=gb2312";
                Response.Filter.Close();
                Response.WriteFile(file.FullName);
                Response.End();
            }
        }
