2. Read Excel

 

- Form data

1. Get the Excel information file

        string filePath = Application.dataPath + "/目标名称.xlsx";//这里是文件路径
   
        //获取Excel文件的信息
        FileInfo fileInfo = new FileInfo(filePath);

2. Open the Excel file information and open the table

        //通过Excel文件信息，打开表格
        using (ExcelPackage excelPackage = new ExcelPackage(fileInfo))
        //using是用来强行资源释放（前括号是打开，后括号是关闭）
        {

        }

3. Which table of this Excel needs to be opened

        using (ExcelPackage excelPackage = new ExcelPackage(fileInfo))
        {
            //取得Excel文件中的第N张表
            ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets[1];
        }

4. Read data

        using (ExcelPackage excelPackage = new ExcelPackage(fileInfo))
        {
            ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets[1];
            for (int i = 2; i < worksheet.Dimension.End.Row; i++)
            //End.Row获得当前表格的最大行数
            {
                Debug.Log("目标名称：" + worksheet.Cells[i, 1].Value.ToString() + " // 设备名称：" + worksheet.Cells[i, 2].Value.ToString() + " // 地址：" + worksheet.Cells[i, 3].Value.ToString());
                //Cells是个二维数组，第一个参数是读取第几行，第二个参数是读取第几列需要ToString出数据

            for (int i = 2; i <= 12; i++)
            {
                //直接向每个表格赋值则是写入
                worksheet.Cells[i, 1].Value = "目标名称" + " " + (i - 1);
                worksheet.Cells[i, 2].Value = "设备地址" + " " + (i - 1);
                worksheet.Cells[i, 3].Value = "地址" + " " + (i - 1);

1. The first and second steps are the same as reading

2. Create a table

using UnityEngine;
using UnityEditor;
using OfficeOpenXml;
using System.IO;

public class Creat
{
    [MenuItem("数据持久化/1.Excel/3.CreatExcel")]
    public static void ChangeExcel()
    {
        string filePath = Application.dataPath + "/00.Excel文件夹/Creat.xlsx";

        ///获取Excel文件的信息（文件中没有这个文件也不会报错）
        FileInfo fileInfo = new FileInfo(filePath);

        ///通过Excel文件信息，打开表格
        using (ExcelPackage excelPackage = new ExcelPackage(fileInfo))//在这里也没有创建Excel文件
        {
            //在新Excel文件中创建叫Sheet1的表格
            ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets.Add("Sheet1");
            worksheet.Cells[1, 1].Value = "目标名称";
            worksheet.Cells[1, 2].Value = "设备地址";
            worksheet.Cells[1, 3].Value = "地址";
            for (int i = 2; i <= 12; i++)
            {
                //直接向每个表格赋值则是写入

                worksheet.Cells[i, 2].Value = "设备地址" + " " + (i - 1);
                worksheet.Cells[i, 3].Value = "地址" + " " + (i - 1);
            }
            excelPackage.Save();//写入后保存表格
        }
        //完成文件创建
    }
}

3. Create a good form

---

5. Common APIs

1. Operation on the form

1. Get the Nth table in the Excel file through the int index
   ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets[1]
2. Get the Excel table
   ExcelWorksheet worksheet1 = excelPackage.Workbook.Worksheets["Sheet1"];
3. Get the number of current sheets
   int i = excelPackage.Workbook.Worksheets.Count;
4. Add a table
   ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets.Add("Sheet2");
5. Add color to the table name (change the header color to green)
   worksheet.TabColor = System.Drawing.Color.ForestGreen;
   

2. Processing data

1. Get the largest row and column in the table
   int row = worksheet.Dimension.End.Row;//row
   int column = worksheet.Dimension.End.Column;//column
2. Get the content in the xth cell
   worksheet.Cells[1, 1].Value.ToString();//Get the content at [1,1], which can be written (write without ToString) or read 

3. Operation on Excel

1. Get an Excel file
   ExcelPackage excelPackage = new ExcelPackage(fileInfo);
2. Save the modified Excel file
   excelPackage.Save();//Save
   excelPackage.SaveAs();//Save as
