更改不会反映在Excel工作表中

Question

我编写了以下调用Excel宏的c＃代码。它运行时没有任何错误，但更改不会反映在Excel中。

这是c＃代码

return new List<Model<T>>(GetRoles());

这是我从上面代码中调用的宏

    private void button1_Click(object sender, EventArgs e)
    {
        Excel.Application xlApp = new Excel.Application();

        Excel.Workbook xlWorkBook;

        //~~> Start Excel and open the workbook.
        //xlWorkBook = xlApp.Workbooks.Open("E:\\Users\\Siddharth Rout\\Desktop\\book1.xlsm");
        xlWorkBook = xlApp.Workbooks.Open("D:\\Excel\\Excel.xlsm");

        Excel.Worksheet sheet = (Excel.Worksheet)xlWorkBook.Worksheets[1];

        Console.WriteLine(sheet.Name);
        sheet.Activate();

        string name = xlApp.ActiveSheet.Name;

        //~~> Run the macros by supplying the necessary arguments
        xlApp.Run("italicize");

        //~~> Clean-up: Close the workbook
        xlWorkBook.Close(false);

        //~~> Quit the Excel Application
        xlApp.Quit();

        //~~> Clean Up
        releaseObject(xlApp);
        releaseObject(xlWorkBook);
    }
