ASP.NET MVC读取Excel数据开源插件：ExcelDataReader

1.  ExcelDataReader 下载地址

2.安装NuGet包

3.引入包之后直接用(简单)： 

using Donvv.BLL;
using Donvv.Model;
using ExcelDataReader;
using System.Collections.Generic;
using System.IO;
using System.Web.Mvc;


namespace Donvv.Controllers
{
    public class ExcelReaderController : Controller
    {
        // GET: ExcelReader
        public void GetExcelData()
        {
            string filePath = "E:\\ExcelData\\GoodsType.xlsx"; ;
            using (var stream = System.IO.File.Open(filePath, FileMode.Open, FileAccess.Read))
            {
                //  - OpenXml Excel files (2007 format; *.xlsx)
                using (var reader = ExcelReaderFactory.CreateReader(stream))
                {
                    // Choose one of either 1 or 2:
                    // 1. Use the reader methods
                    //do
                    //{
                    //    while (reader.Read())
                    //    {
                    //        // reader.GetDouble(0);
                    //    }
                    //}
                    //while (reader.NextResult()) ;
                    // 2. Use the AsDataSet extension method
                    var result = reader.AsDataSet();//dataset
                    var goodsTypeList = new List();//待更新列表
