        public static void GenerateWord(string templateFile, string fileNameWord, string fileNamePdf, Dictionary<string, string> bookmarks, List<InvoiceLineView> invoiceline)
        {
            Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.Application();
            File.Copy(templateFile, fileNameWord, true);
            Microsoft.Office.Interop.Word.Document doc = new Microsoft.Office.Interop.Word.Document();
            object Obj_FileName = fileNameWord;
            object Visible = false;
            object ReadOnly = false;
            object missing = System.Reflection.Missing.Value;
            doc = app.Documents.Open(ref Obj_FileName, ref missing, ref ReadOnly, ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing, ref Visible, ref missing, ref missing, ref missing, ref missing);
            doc.Activate();
            foreach (string bookmarkName in bookmarks.Keys)
            {

                object BookMarkName = bookmarkName;//获得书签名                   
                Range range = doc.Bookmarks.get_Item(ref BookMarkName).Range;//表格插入位置
                range.Text = bookmarks[bookmarkName];
