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：
 1 protected void LinkButton1_Click(object sender, EventArgs e)
 2         {
 3             try
 4             {
 5                 //WriteFile实现下载(word)
 6                 string fileName = "qingpingguo.docx";//客户端保存的文件名
 7                 string filePath = Server.MapPath("~\excel\" + tb1.Text);//路径
 8 
 9                 FileInfo fileInfo = new FileInfo(filePath);
10                 Response.Clear();
11                 Response.ClearContent();
12                 Response.ClearHeaders();
13                 Response.AddHeader("Content-Disposition", "attachment;filename=" + fileName);
14                 Response.AddHeader("Content-Length", fileInfo.Length.ToString());
15                 Response.AddHeader("Content-Transfer-Encoding", "binary");
16                 Response.ContentType = "application/octet-stream";
17                 Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
18                 Response.WriteFile(fileInfo.FullName);
19                 Response.Flush();
20                 Response.End();
21             }
22             catch (Exception ex)
23             {
24                 Response.Write(ex.Message);
25             }
26 
27             /*************以下为流方式下载****************/
28             //string fileName = "aaa.txt";//客户端保存的文件名
29             //string filePath = Server.MapPath("DownLoad/aaa.txt");//路径
30 
31             ////以字符流的形式下载文件
32             //FileStream fs = new FileStream(filePath, FileMode.Open);
33             //byte[] bytes = new byte[(int)fs.Length];
34             //fs.Read(bytes, 0, bytes.Length);
35             //fs.Close();
36             //Response.ContentType = "application/octet-stream";
37             ////通知浏览器下载文件而不是打开
38             //Response.AddHeader("Content-Disposition", "attachment;  filename=" + HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8));
39             //Response.BinaryWrite(bytes);
40             //Response.Flush();
41             //Response.End();
42 
43         }
