Unity 使用 ExcelDataReader 读取Excel表

文章目录

1.下载NuGet包
2.通过NuGet包获取dll
3.将dll复制unity Plugins文件夹下
4.代码获取Excel表内容

1.下载NuGet包

通过NuGet下载：

ExcelDataReader
ExcelDataReader.DataSet
离线下载方法

2.通过NuGet包获取dll

根据编译时程序集找到dll位置，找到与unity3d的.net版本匹配的dll
在这里插入图片描述

3.将dll复制unity Plugins文件夹下

请添加图片描述

4.代码获取Excel表内容

这里给个异步读取Excel表的ExcelHelp类：

using System.Data;
using System.IO;
using System.Threading.Tasks;
using System;public class ExcelHelper
{private string _filePath;private DataSet _cacheDataSet;  // 缓存读取的DataSetprivate readonly object _lock = new object();   // 线程锁public ExcelHelper(string filePath){_filePath = filePath;}// 异步读取Excel数据public async Task<DataSet> ReadExcelAsync(){if (_cacheDataSet != null)return _cacheDataSet;return await Task.Run<DataSet>(() =>{lock (_lock){if (_cacheDataSet == null)  // 双重检查锁定{using (var stream = File.Open(_filePath, FileMode.Open, FileAccess.Read)){using (var reader = ExcelReaderFactory.CreateReader(stream)){_cacheDataSet = reader.AsDataSet();}}}}return _cacheDataSet;});}// 根据 sheet 名获取 DataTablepublic async Task<DataTable> GetSheetByNameAsync(string sheetName){await ReadExcelAsync();return _cacheDataSet.Tables[sheetName];}// 根据 sheet 索引获取 DataTablepublic async Task<DataTable> GetSheetByIndexAsync(int sheetIndex){await ReadExcelAsync();if (sheetIndex >= 0 && sheetIndex < _cacheDataSet.Tables.Count)return _cacheDataSet.Tables[sheetIndex];throw new ArgumentOutOfRangeException("Sheet index out of range");}// 获取指定行的内容（从 0 开始的行索引）public async Task<object[]> GetRowAsync(string sheetName, int rowIndex){var table = await GetSheetByNameAsync(sheetName);if (rowIndex >= 0 && rowIndex < table.Rows.Count){return table.Rows[rowIndex].ItemArray;}throw new ArgumentOutOfRangeException("Row index out of range");}// 获取指定列的内容（从 0 开始的列索引）public async Task<object[]> GetColumnAsync(string sheetName, int columnIndex){var table = await GetSheetByNameAsync(sheetName);if (columnIndex >= 0 && columnIndex < table.Rows.Count){var column = new object[table.Rows.Count];for (int i = 0; i < table.Rows.Count; i++){column[i] = table.Rows[i][columnIndex];}return column;}throw new ArgumentOutOfRangeException("Column index out of range");}// 获取指定单元格内容public async Task<object> GetCellAsync(string sheetName, int rowIndex, int columnIndex){var table = await GetSheetByNameAsync(sheetName);if ( rowIndex >= 0 && rowIndex < table.Rows.Count &&columnIndex >= 0 && columnIndex < table.Columns.Count ){return table.Rows[rowIndex][columnIndex];}throw new ArgumentOutOfRangeException("Row or column index out of range");}// 获取指定 Sheet 行数public async Task<int> GetRowCountAsync(string sheetName){var table = await GetSheetByNameAsync(sheetName);return table.Rows.Count;}// 获取指定 Sheet 列数public async Task<int> GetColumnCountAsync(string sheetName){var table = await GetSheetByNameAsync(sheetName);return table.Columns.Count;}
