            {
                WorkbookPart wbp = xl.AddWorkbookPart();
                WorksheetPart wsp = wbp.AddNewPart<WorksheetPart>();
                Workbook wb = new Workbook();
                FileVersion fv = new FileVersion();
                fv.ApplicationName = "Microsoft Office Excel";

                SheetViews sheetViews = new SheetViews();

                SheetView sheetView = new SheetView();
                sheetView.ShowGridLines = new BooleanValue(false);
                sheetViews.Append(sheetView);
                ws.Append(sheetViews);

                //// add styles to sheet
                wbsp.Stylesheet = CreateStylesheet();
                wbsp.Stylesheet.Save();
                //// add styles to sheet
                ////wbsp.Stylesheet = GenerateStyleSheet();

                wb.Append(fv);

                xl.WorkbookPart.Workbook.Save();


                xl.Close();

Answer 1

The WorkbookViewId property of the SheetView class is a required attribute/property. Try this:

SheetView sheetView = new SheetView();
sheetView.ShowGridLines = new BooleanValue(false);
sheetView.WorkbookViewId = 0;
sheetViews.Append(sheetView);
ws.Append(sheetViews);

That uses the 1st (default) workbook view. Don't worry, you don't have to explicitly create a WorkbookView child of the BookViews class, which is a child of Workbook. Unless you want to, of course. :)
