Unity 创建、读取、改写Excel表格数据

1.导入EPPlus.dll、Excel.dll、Mysql.Data.dll、System.Data.dll；（我这里用的是：Unity2017.3.0）

2.代码如下：

using System.Data;
using System.IO;
using UnityEngine;
using OfficeOpenXml;
using UnityEditor;
using Excel;public class ExcelManager : MonoBehaviour
{#region 创建Excel表格[MenuItem("Excel操作/创建Excel表格")]static void 创建Excel表格(){string _filePath = Application.streamingAssetsPath + "/学生信息.xlsx";string _sheetName = "详情";FileInfo _excelName = new FileInfo(_filePath);if (_excelName.Exists){//删除旧文件，并创建一个新的 excel 文件。_excelName.Delete();_excelName = new FileInfo(_filePath);}//通过ExcelPackage打开文件using (ExcelPackage package = new ExcelPackage(_excelName)){//在 excel 空文件添加新 sheet，并设置名称。ExcelWorksheet worksheet = package.Workbook.Worksheets.Add(_sheetName);//添加列名worksheet.Cells[1, 1].Value = "学号";worksheet.Cells[1, 2].Value = "姓名";worksheet.Cells[1, 3].Value = "性别";//添加一行数据worksheet.Cells[2, 1].Value = 100001;worksheet.Cells[2, 2].Value = "张三";worksheet.Cells[2, 3].Value = "男";//添加一行数据worksheet.Cells[3, 1].Value = 100002;worksheet.Cells[3, 2].Value = "李四";worksheet.Cells[3, 3].Value = "女";//添加一行数据worksheet.Cells[4, 1].Value = 120033;worksheet.Cells[4, 2].Value = "Saw";worksheet.Cells[4, 3].Value = "男";//保存excelpackage.Save();}}#endregion#region 读取Excel表格[MenuItem("Excel操作/读取Excel表格")]static void 读取Excel表格(){DataRowCollection _dataRowCollection = ReadExcel(Application.streamingAssetsPath + "/学生信息.xlsx");for (int i = 0; i < _dataRowCollection.Count; i++){Debug.Log(_dataRowCollection[i][0] + " " + _dataRowCollection[i][1] + " " + _dataRowCollection[i][2]);}}//通过表的索引，返回一个DataRowCollection表数据对象static DataRowCollection ReadExcel(string _path, int _sheetIndex = 0){FileStream stream = File.Open(_path, FileMode.Open, FileAccess.Read, FileShare.Read);IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);DataSet result = excelReader.AsDataSet();return result.Tables[_sheetIndex].Rows;}//通过表的名字，返回一个DataRowCollection表数据对象private DataRowCollection ReadExcel(string _path, string _sheetName){FileStream stream = File.Open(_path, FileMode.Open, FileAccess.Read, FileShare.Read);IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);DataSet result = excelReader.AsDataSet();return result.Tables[_sheetName].Rows;}#endregion#region 改写Excel表格[MenuItem("Excel操作/改写Excel表格")]static void 改写Excel表格(){string path = Application.streamingAssetsPath + "/学生信息.xlsx";FileInfo _excelName = new FileInfo(path);using (ExcelPackage package = new ExcelPackage(_excelName)){ExcelWorksheet worksheet = package.Workbook.Worksheets["详情"];//修改某一行的数据worksheet.Cells[4, 3].Value = "人妖";//保存excelpackage.Save();}}#endregion
