MVC 导出Excel 的其中一方法(View导出excel)

场景:mvc下导出excel

思路:使用View导出excel

步骤:

1.导出标签添加事件

$("#export_A").click(function(){

//省略代码.....   

window.location.href = "/DuplicateTaskManager/DuplicateTaskManager/ExportExcel/?taskId=" + taskId + "&unitId=" + unitId + "&levelId=" + levelId;

});

2.准备View

   public ActionResult ExportExcel(int taskId, int unitId, int levelId)
        {

            HttpContext.Response.ContentType = "application/vnd.ms-excel";
            HttpContext.Response.Charset = "utf-8";
            HttpContext.Response.ContentEncoding = Encoding.UTF8;
            HttpContext.Response.AppendHeader("Content-Disposition", "attachment; filename="" + UTF_FileName("审核结果查询_" + DateTime.Now.ToString("yyyyMMddHHmmss")) + ".xls"");
               //list是需要下载出的数据,和导出设置无关,正常获取数据,在View遍历

         return PartialView(list);


        }
        /// <summary>
        /// 将文件名转为UrlEncode
        /// </summary>
        /// <param name="filename"></param>
        /// <returns></returns>
        private static string UTF_FileName(string filename)
        {
            return HttpUtility.UrlEncode(filename, System.Text.Encoding.UTF8);
        }

3.View 遍历数据

<table border="1">
    <thead>
        <tr>
            <td width="100" rowspan="2">
                单位
            </td>
            <td width="60" rowspan="2">
                审核总数
            </td>
            <td rowspan="2">
                未审核数
            </td>
            <td colspan="<%=ss.Keys.Count%>">
                <span style="margin-left: 40%;">已审核数</span>
            </td>
            <td width="60" rowspan="2">
                已完成审核比率
            </td>
            <td rowspan="2">
                排名
            </td>
        </tr>
        <tr>
            <%
                foreach (var item in ss.Keys)
                {
            %>
            <td width="100">
            <%=ss.Get(item.ToString()) %> 
            </td>
            <%
                }
            %>
        </tr>
        <%
            int i = 1;
            foreach (var item in Model)
            {%>
        <tr>
            <td>
                <%=item.UnItName %>
            </td>
            <td>
                <%=item.SumCount %>
            </td>
            <td>
                <%=item.NotApprovedCount %>
            </td>
            <%
                foreach (var key in ss.Keys)
                {
            %>
            <td>
                <%=item.Dcits.Get(key.ToString()) %>
            </td>
            <%
                }
            %>
            <td>
                <%=string.Format("{0}%", item.CompleteRate.ToString("0.00"))%>
            </td>
            <td>
                <%
                if (i < Model.Count)
                {%>
                <%=i%>
                <%}
                %>
            </td>
        </tr>
        <%
                i++;
            }%>
    </thead>
</table>

结论:简单的导出,大数据下请自己测试.
