一.DLL插件读取

1.1.Excel存放位置

如图 将命名为cook的excel文件存放在Assets根目录下

1.2.使用示例

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

public class ExcelTool : MonoBehaviour
{
    void Start()
    {
        ReadExcel("/cook.xlsx");
    }

    public void ReadExcel(string xmlName)
    {
        FileStream stream = File.Open(Application.dataPath + xmlName, FileMode.Open, FileAccess.Read, FileShare.Read);
        //IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);//读取 Excel 1997-2003版本
        IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);//读取 2007及以后的版本

        DataSet result = excelReader.AsDataSet();

        if (stream != null)
        {
            stream.Close();
        }

        int[] counts = GetCount(result.Tables[0]);
        int rows = counts[0];
        int columns = counts[1];
        Debug.LogError("row:" + rows + "...col:" + columns);
        for (int i = 0; i < rows; i++)
        {
            for (int j = 0; j < columns; j++)
            {
                Debug.LogError(result.Tables[0].Rows[i][j].ToString());
            }
        }
    }

    private int[] GetCount(DataTable dt)
    {
        int i = dt.Rows.Count;
        for (int m = 0; m < dt.Rows.Count; m++)
        {
            if (string.IsNullOrEmpty(dt.Rows[m][0].ToString()))
            {
                i = m;
                break;
            }
        }

        int j = dt.Columns.Count;
        for (int n = 0; n < dt.Columns.Count; n++)
        {
            if (string.IsNullOrEmpty(dt.Rows[0][n].ToString()))
            {
                j = n;
                break;
            }
        }
        return new int[] { i, j };
    }
}

1.3.Excel格式

 1.4.输出显示 

1.5.所需插件

需导入3个dll文件到Plugins文件夹下。

分别是：Excel.dll EPPlus.dll 和 ICSharpCode.SharpZipLib.dl

插件下载https://download.csdn.net/download/lalate/87401837

⚠️注意：上述示例在安卓真机上运行是读取不到的，有解决了的同学欢迎评论补充，或者私信我

二.Excel转成Asset文件，再进行读取

2.1Excel文件存放位置

2.2 编辑模式生成Asset文件，并保存到指定位置 

using System;
using System.Reflection;
using UnityEditor;
using UnityEngine;

public class ExcelReadEditor : Editor
{
    [MenuItem("Excel/批量读表")]
    public static void ReadAllExcel()
    {
        Type typeInfo = typeof(ExcelReadEditor);

        MethodInfo[] methodInfo = typeInfo.GetMethods();
        foreach (MethodInfo mInfo in methodInfo)
        {
            if (mInfo.ToString().StartsWith("Void Create"))
            {
                mInfo.Invoke(null, null);
            }
        }
        Debug.Log("读取全部表成功");
    }

    [MenuItem("Excel/读取Decoration数据")]
    public static void CreateChapterData()
    {
        GetLocalData("SheBei");
        Debug.Log("读取Decoration数据成功");
    }

    //泛型创建 保存本地数据
    public static void GetLocalData(string fileName) where T : LocalDataBase
    {
        T t = CreateInstance();
        string filePath = Application.dataPath + "/Excel/" + "cook-en" + ".xlsx";
        //string filePath = Path.GetFullPath(".") + "\\Excel\\" + "cook-en" + ".xlsx";
        t.data = ExcelRead.GetExcelData(filePath, fileName);
        if (t.data == null) Debug.LogError("数据读取错误");

        string savePath = "Assets/Excel/Data/EN/" + fileName + ".asset";
        AssetDatabase.CreateAsset(t, savePath);
        AssetDatabase.SaveAssets();
        AssetDatabase.Refresh();

        GetLocalDataCH(fileName);
    }
    public static void GetLocalDataCH(string fileName) where T : LocalDataBase
    {
        T t = CreateInstance();
        string filePath = Application.dataPath + "/Excel/" + "cook-ch" + ".xlsx";
        //string filePath = Path.GetFullPath(".") + "\\Excel\\" + "cook-ch" + ".xlsx";
        t.data = ExcelRead.GetExcelData(filePath, fileName);
        if (t.data == null) Debug.LogError("数据读取错误");

        string savePath = "Assets/Excel/Data/CH/" + fileName + ".asset";
        AssetDatabase.CreateAsset(t, savePath);
        AssetDatabase.SaveAssets();
        AssetDatabase.Refresh();
    }
}

⚠️注意：要先在指定位置创建好父文件夹，此脚步要放在Editor文件夹下

2.3创建ExcelRead脚本，读取Excel内容

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

public class ExcelRead
{

    public static T[] GetExcelData(string filePath, string name)
    {
        switch (name)
        {
            case "Entity_SheBei":
                return GetEntity_SheBei(filePath) as T[];
               //。。。
        }

        return null;
    }

    //设备
    private static Entity_SheBei[] GetEntity_SheBei(string filePath)
    {
        int columnNum = 0, rowNum = 0;
        DataRowCollection collect = ReadExcel(filePath, ref columnNum, ref rowNum, 1);
        List list = new List();

        for (int i = 1; i < rowNum; i++)
        {
            if (string.IsNullOrEmpty(collect[i][0].ToString()) || string.IsNullOrEmpty(collect[0][i].ToString())) break;
            Entity_SheBei data = new Entity_SheBei();
            data.name = collect[i][0].ToString();

            for (int j = 1; j < columnNum; j++)
            {
                //Debug.LogError(collect[i][j].ToString());
                data.parts.Add(collect[i][j].ToString());
            }

            list.Add(data);
        }

        return list.ToArray();
    }

    /// 

    /// 读取excel文件内容 
    /// 
    /// 文件路径
    /// 行数
    /// 列数
    /// 第几张表
    /// 
    static DataRowCollection ReadExcel(string filePath, ref int columnNum, ref int rowNum, int table = 0)
    {
        FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read, FileShare.Read);
        IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);

        DataSet result = excelReader.AsDataSet();
        //Tables[0] 下标0表示excel文件中第一张表的数据
        int[] counts = GetRowColumns(result.Tables[table]);
        //columnNum = result.Tables[table].Columns.Count;
        //rowNum = result.Tables[table].Rows.Count;
        rowNum = counts[0];
        columnNum = counts[1];
        Debug.LogError("行:" + rowNum + "...列:" + columnNum);
        return result.Tables[table].Rows;
    }


    private static int[] GetRowColumns(DataTable dt)
    {
        int i = dt.Rows.Count;
        for (int m = 0; m < dt.Rows.Count; m++)
        {
            if (string.IsNullOrEmpty(dt.Rows[m][0].ToString()))
            {
                i = m;
                break;
            }
        }

        int j = dt.Columns.Count;
        for (int n = 0; n < dt.Columns.Count; n++)
        {
            if (string.IsNullOrEmpty(dt.Rows[0][n].ToString()))
            {
                j = n;
                break;
            }
        }
        return new int[] { i, j };
    }
}

2.4 创建数据存储脚本

基类：

using UnityEngine;

public class LocalDataBase : ScriptableObject
{
    public T[] data;
}

 子类：

public class LocalSheBei : LocalDataBase
{

}

 子类对应的实体类：

using System.Collections.Generic;

[System.Serializable]
public class Entity_SheBei
{
    public string name;
    public List parts = new List();
}

2.5  编辑器生成Asset 与属性面板详情

 

 

 

 2.6 Asset数据的使用方式

  Resources.Load方式

 也可以定义一个单例类，直接拖拽：

public LocalSheBei Data_SheBei;
    //数据读取
    public void GetLocalData()
    {
        Debug.LogError(Data_SheBei.name + "..." + Data_SheBei.data.Length);
    }

 三:Excel文件转成json 再以json的方式读取
