Unity package exe to read and write excel table files

Unity Read user configuration information when running , Export the information to be saved in the application to Excel form

1、 Import Excel Read plug-ins

2、 Import opens Windows File and folder tools （ I wrote it before ） 

3、 Usage method

1）、 New script , And define parameters  

    public Button saveBtn;
    public Button readBtn;

    private Action<string> readAction;
    private Action<string> saveAction;

    public Text des;

2）、 Binding of events  

    private void Start()
    {
        saveBtn.onClick.AddListener(OpenFolder);
        readBtn.onClick.AddListener(OpenFile);

        saveAction += SaveFile;
        readAction += GetFile;
    }

3）、 Function realization

 public void OpenFile()
    {
        Mark.OpenDialogHelper.SelectFile(readAction, "Excel file (*.xlsx*)\0*.xlsx*"); // FBX file (*.fbx)\0*.fbx\0

    }
    public void OpenFolder()
    {
        Mark.OpenDialogHelper.SelectFolder(saveAction);

    }
    private void GetFile(string filePath)
    {
        Debug.Log(filePath);
        Read(filePath);
    }

    private void SaveFile(string filePath)
    {
        Debug.Log(filePath);
        Create(filePath);
    }

    private void Create(string path)
    {
        if (Directory.Exists(path))
        {
            string ph = path + "/" + "Tex2.xlsx";
            FileInfo newFile = new FileInfo(ph);
            if (newFile.Exists)
            {
                newFile.Delete();
                newFile = new FileInfo(ph);
            }

            using (ExcelPackage package = new ExcelPackage(newFile))
            {
                ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("ModelInfo");// establish worksheet
                CreateTitle(worksheet);
                CreateContent(worksheet);
                package.Save();
            }
        }

    }

    private void Read(string path)
    {
        StringBuilder sb = new StringBuilder();
        using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read))
        {
            sb.Clear();
            using (ExcelPackage ep = new ExcelPackage(fs))
            {
                // Get all tables  E:\Test\Text.xlsx
                StringBuilder sb1 = new StringBuilder();
                ExcelWorksheets worksheets = ep.Workbook.Worksheets;
                for (int i = 1; i <= worksheets.Count; i++)
                {
                    // The current worksheet  
                    ExcelWorksheet sheet = worksheets[i];
                    // The current worksheet   How many?   Column 
                    int columCount = sheet.Dimension.End.Column;
                    // The current worksheet   How many?   That's ok 
                    int rowCount = sheet.Dimension.End.Row;
                    // From the first few lines \ Which column starts reading data  , It depends on the specific situation 
                    int startRow = 2;
                    int startColum = 1;
                    for (int j = startRow; j <= rowCount; j++)
                    {
                        sb1.Clear();
                        for (int k = startColum; k <= columCount; k++)
                        {
                            if (!string.IsNullOrEmpty(sheet.Cells[j, k].Text))
                            {
                                sb1.Append(sheet.Cells[j, k].Text+"   ");
                            }
                            
                        }
                        string str = $" At present Excel Table No {i} Table reading ： The first  {j}  Row data  ：{sb1.ToString()}\n";
                        sb.Append(str);
                    }

                }
            }

            des.text = sb.ToString();
        }
    }


    private void CreateTitle(ExcelWorksheet worksheet)
    {
        worksheet.Cells[1, 1].Value = " Serial number ";
        worksheet.Cells[1, 2].Value = " name ";
        worksheet.Cells[1, 3].Value = " Number ";
        worksheet.Cells[1, 4].Value = " Company ";
        worksheet.Cells[1, 5].Value = " The unit price ";
        worksheet.Cells[1, 6].Value = " Total price ";
        worksheet.Cells[1, 7].Value = " remarks ";
    }

    private void CreateContent(ExcelWorksheet worksheet)
    {
        for (int i = 2; i <= 5; i++)
        {
            for (int j = 1; j <= 5; j++)
            {
                worksheet.Cells[i, j].Value = i * j;
            }
        }
    }
