1.在Plugins中放入dll，118开头的dll在Unity安装目录下（C:\Program Files\Unity\Editor\Data\Mono\lib\mono\unity）

2.写Excel

public void WriteExcel(){//文件地址FileInfo newFile = new FileInfo(Application.dataPath + "/test.xlsx");//数据操作using (ExcelPackage package = new ExcelPackage(newFile)){//增加数据操作（重点在于这条操作语句与初次创建添加数据不同）ExcelWorksheet worksheet = package.Workbook.Worksheets["test"];if(worksheet == null){worksheet = package.Workbook.Worksheets.Add("test");}//写首行worksheet.Cells[1, 1].Value = "编号";worksheet.Cells[1, 2].Value = "姓名";worksheet.Cells[1, 3].Value = "组号";//添加第二行数据worksheet.Cells[2, 1].Value = "001";worksheet.Cells[2, 2].Value = "王大于";worksheet.Cells[2, 3].Value = "1";//添加第三行数据worksheet.Cells[3, 1].Value = "002";worksheet.Cells[3, 2].Value = "李云香";worksheet.Cells[3, 3].Value = "1";//保存package.Save();}}

3.读Excel

public void ReadExcel(){//加载文件FileStream fileStream = File.Open(Application.dataPath + "/test.xlsx", FileMode.Open, FileAccess.Read);IExcelDataReader excelDataReader = ExcelReaderFactory.CreateOpenXmlReader(fileStream);DataSet result = excelDataReader.AsDataSet();int columns = result.Tables[0].Columns.Count; int rows = result.Tables[0].Rows.Count;Debug.Log("共有：" + columns + "列 " + rows + "行");//第一行为表头，不读取。没有表头从0开始(获取数据)for (int i = 0; i < rows; i++){for (int j = 0; j < columns; j++){// 获取表格中指定行指定列的数据 string value = result.Tables[0].Rows[i][j].ToString();Debug.Log(value);}}fileStream.Close();}
