Named Ranges



            var wb = new XLWorkbook();
            var wsPresentation = wb.Worksheets.Add("Presentation");
            var wsData = wb.Worksheets.Add("Data");

            // Fill up some data
            wsData.Cell(1, 1).Value = "Name";
            wsData.Cell(1, 2).Value = "Age";
            wsData.Cell(2, 1).Value = "Tom";
            wsData.Cell(2, 2).Value = 30;
            wsData.Cell(3, 1).Value = "Dick";
            wsData.Cell(3, 2).Value = 25;
            wsData.Cell(4, 1).Value = "Harry";
            wsData.Cell(4, 2).Value = 29;

            // Create a named range with the data:
            wsData.Range("A2:B4").AddToNamed("PeopleData"); // Default named range scope is Workbook

            // Let's use the named range in a formula:
            wsPresentation.Cell(1, 1).Value = "People Count:";
            wsPresentation.Cell(1, 2).FormulaA1 = "COUNT(PeopleData)";

            // Create a named range with worksheet scope:
            wsPresentation.Range("B1").AddToNamed("PeopleCount", XLScope.Worksheet);

            // Let's use the named range:
            wsPresentation.Cell(2, 1).Value = "Total:";
            wsPresentation.Cell(2, 2).FormulaA1 = "PeopleCount";

            // Copy the data in a named range:
            wsPresentation.Cell(4, 1).Value = "People Data:";
            wsPresentation.Cell(5, 1).Value = wb.Range("PeopleData");

            // For the Excel geeks out there who actually know about
            // named ranges with relative addresses, you can
            // create such a thing with the following methods:

            // The following creates a relative named range pointing to the same row
            // and one column to the right. For example if the current cell is B4
            // relativeRange1 will point to C4.
            wsPresentation.NamedRanges.Add("relativeRange1", "Presentation!B1");

            // The following creates a ralative named range pointing to the same row
            // and one column to the left. For example if the current cell is D2
            // relativeRange2 will point to C2.
            wb.NamedRanges.Add("relativeRange2", "Presentation!XFD1");

            // Explanation: The address of a relative range always starts at A1
            // and moves from then on. To get the desired relative range just
            // add or subtract the required rows and/or columns from A1.
            // Column -1 = XFD, Column -2 = XFC, etc.
            // Row -1 = 1048576, Row -2 = 1048575, etc.
