我把GridView中的数据用一个导出excel的类导出来,但发现里面有些编号原先是以0开头的,比如01001,但导出来到Excel中发现都成1001了,0没了。我想把excel的格式设成文本格式,但不知怎么弄。

打开Excel然后设置好格式另存别计算XML格式保存。
你看我的空间里有一个类可以用的,我公司里一直用的就是这个了
设置单元格格式
或使用'
mySheet.Cells(1,9).NumberFormatLocal = "@"
Excel.Range r = mySheet.get_Range(mySheet.Cells[1, 1], mySheet.Cells[1,3]);
r.NumberFormat = "@";
或使用Stream
