C#实现word文件下载的代码

效果：

思路：

简单的有两种方式下载，一种是流下载，一种是writefile下载。以下是使用writefile下载。

代码：

protected void linkbutton1_click(object sender, eventargs e)
        {
            try
            {
                //writefile实现下载(word)
                string filename = "qingpingguo.docx";//客户端保存的文件名
                string filepath = server.mappath("~\\excel\\" + tb1.text);//路径

                fileinfo fileinfo = new fileinfo(filepath);
                response.clear();
                response.clearcontent();
                response.clearheaders();
                response.addheader("content-disposition", "attachment;filename=" + filename);
                response.addheader("content-length", fileinfo.length.tostring());
                response.addheader("content-transfer-encoding", "binary");
                response.contenttype = "application/octet-stream";
                response.contentencoding = system.text.encoding.getencoding("gb2312");
                response.writefile(fileinfo.fullname);
                response.flush();
                response.end();
            }
            catch (exception ex)
            {
                response.write(ex.message);
            }

            /*************以下为流方式下载****************/
            //string filename = "aaa.txt";//客户端保存的文件名
            //string filepath = server.mappath("download/aaa.txt");//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();

        }
