需要加入库文件 Excel.dll 和ICSharpCode.SharpZipLib库文件，官方链接 http://exceldatareader.codeplex.com/

读取Excel

需要添加命名空间    using 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);
        Debug.LogError("stream    " + stream);
        IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);          //读取2007以后版本
        //IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);     //读取2003以后版本

        DataSet result = excelReader.AsDataSet();
        Debug.LogError("result   " + result);
        excelReader.Close();
        

        int columns = result.Tables[0].Columns.Count;
        int rows = result.Tables[0].Rows.Count;

        for (int i = 0; i < rows; i++)
        {
            for (int j = 0; j < columns; j++)
            {
                string nvalue = result.Tables[0].Rows[i][j].ToString();
                Debug.Log(nvalue);
            }
        }
        return result;
    }

    public static List<DepenceTableData> Load(string path)
    {
        Debug.LogError(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;
}

写入Excel

此时需要一个Excel.dll的姐妹，EPPlus.dll 官方链接 https://epplus.codeplex.com/releases/view/118053

需要添加命名空间    using OfficeOpenXml;

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using OfficeOpenXml;
using System.IO;

public class PrintExcel : MonoBehaviour {
    public List<DepenceTableData> listdata;
    void Start () {
        //读
        Text T = GameObject.Find("Canvas/Text").GetComponent<Text>();
        T.text = "";//清空一开始的文本
        listdata = DoExcel.Load(Application.streamingAssetsPath + "/Test2003.xls");
        Debug.LogError("listdata"+listdata);
       
        foreach (var listing in listdata)
        {

            Debug.LogError("listing.instruct" + listing.instruct);

            Debug.LogError("listing.word" + listing.word);

            //print(listing.instruct + "     " + listing.word);
            
            T.text += (listing.instruct + "     " + listing.word + "\n").ToString();
        }

        //写
        WriteExcel(Application.streamingAssetsPath + "/Test2007.xlsx");

    }


    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();
        }
    }


}
