 运行效果

上面的是webform版本的  用mvc搞了一下午遇到了一些问题 这次更新时间在2018/9/28

添加下列代码

  {
                    FileStream os = new FileStream(Server.MapPath("/Content/Word/" + jibenxinxis.xingming + ".doc"), FileMode.OpenOrCreate);
                    doc.Write(os);

                    return File(new FileStream(Server.MapPath("/Content/Word") + "\\" + jibenxinxis.xingming + ".doc", FileMode.Open), "text/plain", Server.UrlEncode(jibenxinxis.xingming + ".doc"));
                }

必须是get  不可以是ajax

 这样才可以return file  最好用a标签访问控制器
