以上方法为 读取模板，然后写信息后 另存为 新的 excel（模板内容为发生变化）
上述方法可以返回一个另存excel的路径path，
然后下述方法可以弹出另存为对话框：
FileInfo fi = new FileInfo(path);//excel路径
HttpResponse contextResponse = HttpContext.Current.Response;
contextResponse.Clear();
contextResponse.Buffer = true;
contextResponse.Charset = "GB2312"; //设置了类型为中文防止乱码的出现
contextResponse.AppendHeader("Content-Disposition", String.Format("attachment;filename={0}", list[1] + ".xls")); //定义输出文件和文件名
contextResponse.AppendHeader("Content-Length", fi.Length.ToString());
contextResponse.ContentEncoding = Encoding.UTF8;
contextResponse.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
contextResponse.WriteFile(fi.FullName);
contextResponse.Flush();
contextResponse.End();
