我在创建文件后尝试下载excel文件,并且出现以下错误:

            file = new FileInfo(Path.Combine(wwwrootPath, fileName));
        }
        using (ExcelPackage package = new ExcelPackage(file))
        {
            ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("Employee");
            worksheet.Cells[1, 1].Value = "ID";
            worksheet.Cells[1, 2].Value = "Name";
            worksheet.Cells[1, 3].Value = "Gender";
            worksheet.Cells[1, 4].Value = "Salary (in …
