MVC 导出Execl 的总结几种方式 （二）

  接着上面的来，继续导出Execl 的功能

  使用FileResult 方式直接可以生产Execl ，这样我们将会写大量处理后台的代码，个人感觉不好，只是展示出来，提供参考

 

第一步：编辑控制器

 

 public FileResult ExportFile()
        {
            var list = GetList();

            var sbHtml = new StringBuilder();
            string title = "order";
            //标题
            sbHtml.Append("<table border='1' cellspacing='0' cellpadding='0'>");
            sbHtml.Append("<tr>");
            sbHtml.AppendFormat("<td style='font-size: 14px;text-align:center; font-weight:bold;' height='30' colspan='3'>{0}</td>", title);
            sbHtml.Append("</tr>");
            sbHtml.Append("</table>");
            sbHtml.Append("<table border='1' cellspacing='0' cellpadding='0' style='font-size: 12px;'>");
            var lstTitle = new List<string> { "Year", "Week", "Date" }; //编写表头
            sbHtml.Append("<tr>");
            foreach (var item in lstTitle)
            {
                sbHtml.AppendFormat("<td style='text-align:center;background-color: #DCE0E2; font-weight:bold;' height='25'>{0}</td>", item);
            }
            sbHtml.Append("</tr>");
            int i = 1;

            var strDataType = string.Empty;
            var strQuestion = string.Empty;

            foreach (var item in list)
            {

                sbHtml.Append("</tr>");
                sbHtml.AppendFormat("<td align='center'>{0}</td><td align='center'>{1}</td><td align='center'>{2}</td>", item.Id, item.Name,item.CreateTime.ToString("yyyy-MM-dd hh:mm:ss") );
                sbHtml.Append("</tr>");
                i++;

            }
            sbHtml.Append("</table>");

            byte[] fileContents = Encoding.Default.GetBytes(sbHtml.ToString());

            string fileName = title + ".xls";

            if (Request.Browser.Browser == "IE")
            {
                Response.Charset = "GB2312";
                Response.ContentEncoding = Encoding.GetEncoding("GB2312");
                Response.AddHeader("Content-Disposition", string.Format("attachment; filename=\"{0}\"", HttpUtility.UrlEncode(fileName, Encoding.UTF8)));
            }
            return File(fileContents, "application/ms-excel", fileName);
        }
