• 将 GridView 中的内容导出到 Excel 中多个工作表(Sheet) 的方法


    Excel 可以保存成 xml 格式,并且支持Sheet功能,因此,我们就可以利用这个功能将 Gridview 导出到多个 Sheet  中去。而且可以很好地控制导出的格式。下面就是完整的代码(注意:本站的代码都是可以直接复制、保存成aspx文件运行的。):

    例子

    ASPX 代码

    另外,请注意:代码里面添加了\r\n换行,是为了生成出来的xml格式有换行,实际可以不用。

    如果是DataTable,DataSet,可以直接导出成文件。下面是完整的源代码:
