word编程补充-关于word打印的实际应用

　　实际报表打印可能需要同时写入表格类型数据和报表主题、时间、单位等内容，因此需要同时处理单一零散数据和有规则的表格数据。通过改写InsertBlemDatatoBookmark方法，可以做到。（相关内容参考以前随笔）

　　方法全文如下：(包括说明)

　　参数：FileName--报表模板文件名称

　　　　　savefilename--报表生成后另存文件名称

　　　　　dt-报表的表格数据

　　　　　has-报表的零散数据

　　　　　introw-报表表格数据表格头所在模板行　

　　public void InsertBlemDatatoBookmark(string FileName, System.Data.DataTable dt,
                    string savefilename, System.Collections.Hashtable has,int introw)
        {

            Microsoft.Office.Interop.Word.Application wApp = null;
            this.OpenWordDoc(FileName, ref wDoc, ref wApp);
            object oEndOfDoc = "http://www.cnblogs.com/Andmm/admin/file://endofdoc/";
            object missing = System.Reflection.Missing.Value;

            //查找表标签-枚举出所有非表格的标签（包含table的标签除外）
            System.Collections.IEnumerator enu = wApp.ActiveDocument.Bookmarks.GetEnumerator();

            Microsoft.Office.Interop.Word.Bookmark bk = null;
            object tableobj = null;
            while (enu.MoveNext())
            {
                bk = (Microsoft.Office.Interop.Word.Bookmark)enu.Current;

                if (bk.Name.ToString().Trim().IndexOf("table") > -1)
                {
                    tableobj = bk.Name.ToString(); break;

            object unitp = Microsoft.Office.Interop.Word.WdUnits.wdParagraph;//段落方式,对于表格可以选择到表格行后的换车符,对于跨行合并的行选择,我能找到的最简单方式

#region 多行复杂表头的获取方法（简单的下移行复制是不无法复制复杂表头的，这应该是word的缺陷，必须要扩展到行尾）

            ////定位到表格第1单元格
            //WApp.Selection.Tables[1].Cell(1, 1).Select();
            ////定位到第1个单元格第1个字符前         
            //WApp.Selection.HomeKey(ref unith, ref missing);
            ////扩展到行尾,选择表第1行           
            //WApp.Selection.EndKey(ref unith, ref extend);
            ////定义表格标题的行数量,titlerow为参数           
            //object strtitlerow=titlerow-1;
            ////移动光标选择第1行的末尾段落标记           
            //WApp.Selection.MoveDown(ref unitp, ref count, ref extend);
            ////选择下一行,因为合并的原因,如表格标题最后列是合并,只选择了2行的部分
            //            WApp.Selection.MoveDown(ref unitu, ref strtitlerow, ref extend);
            ////扩展到该行的末端,保证合并行能全部选择到
            //            WApp.Selection.EndKey(ref unith, ref extend);
            ////复制选择内容到剪贴板
            //            WApp.Selection.Copy();
            ////下面是移动光标到任何位置并粘贴内容.我程序中目的是到表格换页的时候自动插入下一页的表头.
            //WApp.Selection.Tables[1].Cell(System.Convert.ToInt32(strRownum), 1).Select();
            //WApp.Selection.HomeKey(ref unith, ref missing);
            //WApp.Selection.Paste();
