namespace HideExcelRow
    class Program

            //initialize a new instance object
            Workbook workbook = new Workbook();
            //open a template excel file
            //get the first worksheet 
            Worksheet sheet = workbook.Worksheets[0];
            //hide the 12th row of Sheet

            //save the Excel file
            workbook.SaveToFile("sample.xlsx", ExcelVersion.Version2010);
            //launch the Excel file

Imports Spire.Xls
