        {
            try
            {
                wordApp.ActiveWindow.ActivePane.View.SeekView = Word.WdSeekView.wdSeekCurrentPageHeader;
                object oAlignment = Microsoft.Office.Interop.Word.WdPageNumberAlignment.wdAlignPageNumberCenter;
                object oFirstPage = bHeader;
                //Microsoft.Office.Interop.Word.WdHeaderFooterIndex   WdFooterIndex   =   Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary;                switch (strType)
                {
                    case "Center":
                        oAlignment = Microsoft.Office.Interop.Word.WdPageNumberAlignment.wdAlignPageNumberCenter;
                        break;                    case "Right":
                        oAlignment = Microsoft.Office.Interop.Word.WdPageNumberAlignment.wdAlignPageNumberRight;
                        break;                    case "Left":
                        oAlignment = Microsoft.Office.Interop.Word.WdPageNumberAlignment.wdAlignPageNumberLeft;
                        break;
                }                wordApp.Selection.Sections[1].Footers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].PageNumbers.Add(ref   oAlignment, ref   oFirstPage);
                wordApp.Selection.Sections[1].Footers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].PageNumbers.NumberStyle =
                    Microsoft.Office.Interop.Word.WdPageNumberStyle.wdPageNumberStyleTradChinNum1;
            }
            catch (Exception ex)
            {
                throw ex;
            }
