首先要注意的点：
1.你的unity版本是多少，去对应的安装目录中取dll
2.System.Data.dll 在D:\Program Files\Unity2017.2\Editor\Data\Mono\lib\mono\2.0
3.I18N开头的dll 在 D:\Program Files\Unity2017.2\Editor\Data\Mono\lib\mono\unity

4.2017.2版本demo工程（包含其他所需要的excel相关dll） 下载

读excel

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Data;
using System.IO;
using Excel;

public class DoExcel {
    public static DataSet ReadExcel(string path)
    {
        FileStream stream = File.Open(path, FileMode.Open, FileAccess.Read, FileShare.Read);
        IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
        DataSet result = excelReader.AsDataSet();
        excelReader.Close();
        return result;

    }

    public static List<DepenceTableData> Load(string path)
    {
        List<DepenceTableData> _data = new List<DepenceTableData>();
        DataSet resultds = ReadExcel(path);
        int column = resultds.Tables[0].Columns.Count;
        int row = resultds.Tables[0].Rows.Count;
        Debug.LogWarning(column + "  " + row);
        for(int i=1;i<row;i++)
        {
            DepenceTableData temp_data;
            temp_data.instruct = resultds.Tables[0].Rows[i][0].ToString();
            temp_data.word = resultds.Tables[0].Rows[i][1].ToString();
            Debug.Log(temp_data.instruct + "  " + temp_data.word);
            _data.Add(temp_data);
        }
        return _data;
    }

}

public struct DepenceTableData
{
    public string word;
    public string instruct;
}

写excel

public static void WriteExcel(string outputDir)
    {
        //string outputDir = EditorUtility.SaveFilePanel("Save Excel", "", "New Resource", "xlsx");
        FileInfo newFile = new FileInfo(outputDir);
        if (newFile.Exists)
        {
            newFile.Delete();  // ensures we create a new workbook
            newFile = new FileInfo(outputDir);
        }
        using (ExcelPackage package = new ExcelPackage(newFile))
        {
            // add a new worksheet to the empty workbook
            ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("Sheet1");
            //Add the headers
            worksheet.Cells[1, 1].Value = "ID";
            worksheet.Cells[1, 2].Value = "Product";
            worksheet.Cells[1, 3].Value = "Quantity";
            worksheet.Cells[1, 4].Value = "Price";
            worksheet.Cells[1, 5].Value = "Value";

            //Add some items...
            worksheet.Cells["A2"].Value = 12001;
            worksheet.Cells["B2"].Value = "Nails";
            worksheet.Cells["C2"].Value = 37;
            worksheet.Cells["D2"].Value = 3.99;

            worksheet.Cells["A3"].Value = 12002;
            worksheet.Cells["B3"].Value = "Hammer";
            worksheet.Cells["C3"].Value = 5;
            worksheet.Cells["D3"].Value = 12.10;

            worksheet.Cells["A4"].Value = 12003;
            worksheet.Cells["B4"].Value = "Saw";
            worksheet.Cells["C4"].Value = 12;
            worksheet.Cells["D4"].Value = 15.37;

            //save our new workbook and we are done!
            package.Save();
        }
    }

excel写入的表格 row，rol都是 从1 开始
