操作流程：

1、清除缓存区流中的所有内容的输出。Response.Clear()

2、声明缓冲输出。Response.Buffer = true

3、设置输出流编码。Response.Charset = "GB2312"

4、添加输出流。Response.AppendHeader("Content-Disposition", "attachment;filename="+Model.Name+".doc");

5、设置输出流位简体中文。Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");

6、设置输出文件类型为word文件。

7、
