点滴积累【C#】---C#实现下载word

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();

         }
