Unity编辑器—Excel转Xml和Asset数据

Unity版本 2019.4.9f1

准备工作

1. 安装Excel的拓展库，百度网盘提取码1234
2. 新建一个Plugins文件夹，将下载的拓展库放进去。
3. 创建资源文件夹
   

开始扣代码

1. 创建基本数据类型

ExItem可以根据自己后期需要定义多个类型使用

using System.Collections.Generic;
using UnityEngine;

namespace Data
{
    
    
    [System.Serializable]
    public class ExItem
    {
    
    
        public uint itemId;  // uint为无符号整型
        // 可以自定义所需数据的类型
        // public int itemID;
        // public string itemName;
        public List<string> itemData;
    }
    public class ItemManager : ScriptableObject
    {
    
    
        public ExItem[] dataArray;
    }

    public class ExCell
    {
    
    
        public string name;
        public string info;
    }
}

2. 创建地址类型

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ExcelConfig
{
    
    
    /// <summary>
    /// 存放excel表文件夹的的路径
    /// </summary>
    public static readonly string excelPath = Application.dataPath + "/Resources/Config/Excel/";

    /// <summary>
    /// 存放Excel转化的Assest文件的文件夹路径
    /// </summary>
    public static readonly string assetPath = "Assets/Resources/Config/AssetsFile/";

    /// <summary>
    /// 存放Excel转化的xml文件的文件夹路径
    /// </summary>
    public static readonly string xmlPath = "Assets/Resources/Config/Xml/";
}

3.工具代码

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

public class ExcelTool
{
    
    
    static DataRowCollection ReadExcel(string filePath, ref int columnNum, ref int rowNum)
    {
    
    
        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
        columnNum = result.Tables[0].Columns.Count;
        rowNum = result.Tables[0].Rows.Count;
        return result.Tables[0].Rows;
    }
    /// <summary>
    /// 读取表数据，生成对应的数组
    /// </summary>
    /// <param name="filePath">excel文件全路径</param>
    /// <returns>Item数组</returns>
    public static ExItem[] CreateItemArrayWithExcel(string filePath)
    {
    
    
        //获得表数据
        int columnNum = 0, rowNum = 0;
        DataRowCollection excelData = ReadExcel(filePath, ref columnNum, ref rowNum);

        //根据excel的定义，第二行开始才是数据
        ExItem[] array = new ExItem[rowNum - 1];
        for (int i = 1; i < rowNum; i++)
        {
    
    
            ExItem item = new ExItem();
            //解析每列的数据
            item.itemId = uint.Parse(excelData[i][0].ToString());
            item.itemData = new List<string>();
            for (int j = 0; j < columnNum; j++)
            {
    
    
                item.itemData.Add(Convert.ToString(excelData[i][j]));
            }
            array[i - 1] = item;
        }
        return array;
    }

    public static List<List<ExCell>> ReadExcelInfo(string filePath)
    {
    
    
        // 获取表格情况 columnNum竖列，rowNum横排
        int columnNum = 0, rowNum = 0;
        DataRowCollection excelData = ReadExcel(filePath, ref columnNum, ref rowNum);
        // Debug.Log("表格情况:" + columnNum + "/" + rowNum);

        List<List<ExCell>> list = new List<List<ExCell>>();
        for (int i = 1; i < rowNum; i++)
        {
    
    
            List<ExCell> item = new List<ExCell>();
            for (int j = 0; j < columnNum; j++)
            {
    
    
                ExCell excell = new ExCell();
                excell.name = Convert.ToString(excelData[0][j]);
                excell.info = Convert.ToString(excelData[i][j]);
                // Debug.Log("ID:" + itemInfo.name + "/" + itemInfo.info);
                item.Add(excell);
            }
            list.Add(item);
        }
        return list;
    }
}

4.编辑器代码

新建Editor文件夹，代码需新建在Editor文件夹里

using Data;
using System.Collections.Generic;
using System.IO;
using System.Xml;
using UnityEditor;

public class ExcelBuild : Editor
{
    
    

    [MenuItem("ExcelBuild/ExcelToAsset")]
    public static void Excel2Asset()
    {
    
    
        // 检测文件夹是否存在
        if (Directory.Exists(ExcelConfig.excelPath))
        {
    
    
            //List<>
            // 获取文件夹信息
            DirectoryInfo direction = new DirectoryInfo(ExcelConfig.excelPath);
            FileInfo[] files = direction.GetFiles("*", SearchOption.AllDirectories);
            for (int i = 0; i < files.Length; i++)
            {
    
    
                if (files[i].Name.EndsWith(".xlsx"))
                {
    
    
                    ExportExcelToAsset(ExcelConfig.excelPath + files[i].Name, files[i].Name.Substring(0, files[i].Name.IndexOf('.')));
                }
            }
        }
        else
        {
    
    
            // 创建文件夹
            Directory.CreateDirectory(ExcelConfig.excelPath);
            // 给点提示
            // throw new System.Exception("Excel文件夹为空");
        }

        // 刷新视图
        AssetDatabase.Refresh();
    }

    public static void ExportExcelToAsset(string path, string name)
    {
    
    
        ItemManager manager = CreateInstance<ItemManager>();

        // 赋值
        manager.dataArray = ExcelTool.CreateItemArrayWithExcel(path);

        // 确保文件是新的
        if (File.Exists(ExcelConfig.assetPath + name + ".asset"))
        {
    
    
            File.Delete(ExcelConfig.assetPath + name + ".asset");
        }

        //asset文件的路径 要以"Assets/..."开始，否则会报错
        string assetPath = string.Format("{0}{1}.asset", ExcelConfig.assetPath, name);

        // Debug.Log("转化的数据:" + manager.dataArray.Length);

        // 生成Asset文件
        AssetDatabase.CreateAsset(manager, assetPath);
        AssetDatabase.SaveAssets();
        AssetDatabase.Refresh();
    }

    [MenuItem("ExcelBuild/ExcelToXml")]
    public static void Excel2Xml()
    {
    
    
        // 检测文件夹是否存在
        if (Directory.Exists(ExcelConfig.excelPath))
        {
    
    
            //List<>
            // 获取文件夹信息
            DirectoryInfo direction = new DirectoryInfo(ExcelConfig.excelPath);
            FileInfo[] files = direction.GetFiles("*", SearchOption.AllDirectories);
            for (int i = 0; i < files.Length; i++)
            {
    
    
                if (files[i].Name.EndsWith(".xlsx"))
                {
    
    
                    ExportExcel2Xml(ExcelConfig.excelPath + files[i].Name, files[i].Name.Substring(0, files[i].Name.IndexOf('.')));
                }
            }
        }
        else
        {
    
    
            // 创建文件夹
            Directory.CreateDirectory(ExcelConfig.excelPath);
        }

        // 刷新视图
        AssetDatabase.Refresh();
    }

    public static void ExportExcel2Xml(string path, string name)
    {
    
    
        List<List<ExCell>> list = ExcelTool.ReadExcelInfo(path);
        // Debug.Log("表格长度" + list.Count);

        string xmlPath = ExcelConfig.xmlPath + "/" + name + ".xml";

        // 文件夹不存在？
        if (!File.Exists(ExcelConfig.xmlPath))
        {
    
    
            Directory.CreateDirectory(ExcelConfig.xmlPath);
            // throw new System.Exception("Xml文件夹为空");
        }
        // 文件存在？
        if (File.Exists(xmlPath))
        {
    
    
            File.Delete(xmlPath);
        }
		
		// 创建xml文件
        XmlDocument xml = new XmlDocument();
        // 创建最上一层的根节点
        XmlElement root = xml.CreateElement("elements");
        for (int i = 0; i < list.Count; i++)
        {
    
    
            // 创建每一行的子节点信息
            XmlElement element = xml.CreateElement("element");
            for (int j = 0; j < list[i].Count; j++)
            {
    
    
                // Debug.Log("cell数量" + list[i][j].name);
                // 设置子节点的内容
                element.SetAttribute(list[i][j].name, list[i][j].info);
            }
           	// 添加到最上层节点下
            root.AppendChild(element);
        }
		// 将根节点添加到xml里
        xml.AppendChild(root);
        // 保存xml文件
        xml.Save(xmlPath);
    }
    
}
