C#操作Excel
各位老师朋友帮帮小弟，公司想用C#做这么一个程序：把Dataset数据导入到一个已有模板的Excel中，如何导入？
目前我的困惑时，模板占用了一定的行数，但是我不知道占用几行，所以我从Dataset往里面导数据的时候，无法确定起始导入行？这个问题该如何解决啊！请大侠们赐教！小弟在线等....急啊！ --------------------编程问答--------------------
--------------------编程问答-------------------- anbin0814 我用的是Microsoft.Office.Interop.Excel.Application这个com组件，导出是没有问题的，问题的关键是我要把数据（Dataset里面的数据）导入到以用模板的Excel中，如果没有模板我可以从第一行导入，但是现在有模板了，占用行数不去定，可以是3,4行等，我如何确定我要从哪一行开始导入Dataset里面的数据！ --------------------编程问答-------------------- 我想确定我导入数据的起始行 --------------------编程问答-------------------- public void INSERT_Excel(DataView dvs,string strPath,string Name)

--------------------编程问答-------------------- 现在有很多开源的dll,可以引用open office,Flex,NPOI等等。只是你得自己看它们的API,简单的导出写入肯定很轻松搞定

--------------------编程问答-------------------- 问题还没解决！呜呜.... --------------------编程问答-------------------- 模版不知道怎么用，那个高手给个实例看看

用OpenExcel.dll，封装的OpenXML，不过需要Office2007以上版本，操作很简单，性能也比2003的好

能给出代码吗？
补充：.NET技术 , C#
