Excel表格和Unity

1.配置

下載EPPlus.dll

鏈接：https://pan.baidu.com/s/1l0FYTf8nATrPdEt6fXJ6Kg?pwd=1111
提取碼：1111

將dll檔案拖拽到Assets/Plugins

Assets下新建檔案夾Editor，右鍵Editor點擊Show in Explorer，新建Excel表格檔案（后綴.xlsx），表格檔案放在Assete/Editor中，

2.讀取表格

引入命名空間 ：using OfficeOpenXml ; using System.IO;

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using OfficeOpenXml;
using System.IO;
public class NewRead : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        string filepath = Application.dataPath + "/Editor/內容.xlsx";
        //獲取Excel檔案的資訊
        FileInfo fileInfo = new FileInfo(filepath);
        //通過Excel表格的檔案資訊，打開Excel表格
        using (ExcelPackage excelPackage = new ExcelPackage(fileInfo))
        {
            //對檔案操作

            //取得第一張表
            ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets[1];
            //
            for (int i = worksheet.Dimension.Start.Row; i <= worksheet.Dimension.End.Row; i++)
            {
                for (int j = worksheet.Dimension.Start.Column; j <= worksheet.Dimension.End.Column; j++)
                {
                    string s = worksheet.Cells[i, j].Value.ToString();
                    Debug.Log(s);
                }
            }
        }//關閉檔案
    }
}

ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets[1];讀取第一個表格

worksheet為如圖所示，且從1開始，不是從0開始，

3.寫入表格

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using OfficeOpenXml;
using System.IO;
public class NewRead : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        string filepath = Application.dataPath + "/Editor/內容.xlsx";
        //獲取Excel檔案的資訊
        FileInfo fileInfo = new FileInfo(filepath);
        //通過Excel表格的檔案資訊，打開Excel表格
        using (ExcelPackage excelPackage = new ExcelPackage(fileInfo))
        {
        	//對檔案操作
 			worksheet.Cells[1, 1].Value = https://www.cnblogs.com/Leslielei/archive/2023/05/25/20；
            //保存
            excelPackage.Save();
        }//關閉檔案
    }
}

4.創建Excel表格

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using OfficeOpenXml;
using System.IO;
public class NewRead : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        string filepath = Application.dataPath + "/Editor/內容.xlsx";
        //獲取Excel檔案的資訊
        FileInfo fileInfo = new FileInfo(filepath);
        //通過Excel表格的檔案資訊，打開Excel表格
        using (ExcelPackage excelPackage = new ExcelPackage(fileInfo))
        {
        	//對檔案操作
        	//創建表
            ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets.Add("sheet1");
            excelPackage.Workbook.Worksheets.Add("sheet2");
            excelPackage.Workbook.Worksheets.Add("sheet3");
            //洗掉表
            ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets.Delete("sheet1");
            //保存
            excelPackage.Save();
        }//關閉檔案
    }
}

5.打包

如果dll檔案再Editor下，unity打包不會打包Editor內容，不會報錯，

如果不在，則需要將unity的.net2.0子集改為.net2.0,打包才不會出錯，
