我使用EPPLUS Excel库以Excel格式导出数据.我希望当excel下载时会询问密码.我试过以下代码.

FileInfo newFile = new FileInfo("sample.xlsx");
using (ExcelPackage package = new ExcelPackage(newFile)
{
    ExcelWorksheet ws = package.Workbook.Worksheets.Add("demo");
    ws.Cells[A1].LoadFromDataTable(dataTable, false);
    package.Workbook.Protection.SetPassword("EPPLUS");
    package.Save();
}
