Ayuda con Microsoft.Office.Interop y c#

Question

Hola, por favor necesito ayuda, necesito crear un archivo de excel que contenga una columna de celdas con validacion de datos tipo lista, como puedo hacer esto? he intentado usar: "xlsRange.FormulaLabel" y "xlsWorkbook.AcceptLabelsInFormulas = true" debido a que mis celdas de la lista las necesito en otra hoja de excel pero siempre veo un error.

Aqui mi codigo:

public void ConvertXMLToExcel(string strFileName)
            {
                int vcont=1;
                int vrow = 1;
                int vcol = 0;
                int vsheet = 0;
                int IdProcessExcell = 0;
                XDocument xmldoc = XDocument.Load(strFileName);
                try
                {
                    if (xmldoc.Elements().Count() > 0)
                    {
                        xlsApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
                        IdProcessExcell=System.Diagnostics.Process.GetProcessesByName("Excel")[0].Id;
                        xlsApp.DisplayAlerts = false;

                        foreach (XElement XLibro in xmldoc.Element("Excel").Elements("Libro"))
                        {
                            xlsWorkbook = xlsApp.Workbooks.Add(true);
                            //xlsWorkbook.AcceptLabelsInFormulas = true;
                            foreach (XElement XHoja in XLibro.Elements())
                            {
                                vsheet = vsheet + 1;
                                if (vsheet > 1)
                                    xlsWorksheet = (Microsoft.Office.Interop.Excel.Worksheet)xlsWorkbook.Worksheets.Add(Type.Missing, Type.Missing, 1, Microsoft.Office.Interop.Excel.XlSheetType.xlWorksheet);
                                else
                                    xlsWorksheet = (Microsoft.Office.Interop.Excel.Worksheet)(xlsWorkbook.Worksheets[vsheet]);
                                xlsWorksheet.Activate();
