MiniExcel轻量级开源组件使用
开源地址
添加链接描述
通常复杂的EXCEL操作采用NPIO组件，优点：性能优越，支持各种复杂操作。缺点：比较繁琐和重量级
MiniExcel:则可以满足大部分应用场景，又是轻量级
Guget:搜MiniExcel安装组件
导入&读取Excle
文档简介;
读/导入 Excel
- Query 查询 Excel 返回强型别 IEnumerable 数据 [Try it]
public class UserAccount
public Guid ID get; set;
public string Name get; set;
public DateTime BoD get; set;
public int Age get; set;
public bool VIP get; set;
public decimal Points get; set;
var rows = MiniExcel.Query<UserAccount>(path);
// or
using (var stream = File.OpenRead(path))
var rows = stream.Query<UserAccount>();
一句代码搞定，真TMD爽。
实践
前端：
<button class="layui-btn" lay-event="download" onclick="download()"> <i class="layui-icon"></i>下载模板</button>
<button class="layui-btn" lay-event="upload" id="upload"> <i class="layui-icon"></i>上传Excel</button>
<a href="javascript:;" class="a-upload">
<input type="file" name="" id="">点击这里上传文件
</a>
<!--表格容器-->
<table class="layui-hide" id="currentTableId" lay-filter="currentTableFilter"></table>
<script>
function download()
var filename = "品号信息.xlsx";
var url = '/MinExcel/RequestDownloadFile?filename=' + filename;
window.open(url);
;
//刷新表格函数
function reloadTable()
layui.table.reload('currentTableId',
page:
curr: 1
, where:
type: "select"
);
layui.use(['form', 'table', 'layer', 'upload'], function ()
var $ = layui.jquery,
form = layui.form,
upload = layui.upload,

table = layui.table;
//指定允许上传的文件类型
upload.render(

//表格数据加载

]],
skin: 'line', //表格风格 line （行边框风格）row （列边框风格）nob （无边框风格）

return
