写流文件的方式把页面中的数据导到Excel的终极代码

在开发一个小项目的时候，当时说功能简单，但是要实现数据导出功能，不用太复杂，就有ASP.net那个response.write的功能就行。

想着是简单，可是实践中真是累死人了，跟大家一样老是有的文件出现乱码，找啊试啊最终这个中是比较可靠。现在粘出来大家分享。

如果有更高的需求还是用NPOI吧。

1.在页面上多放一个gridView控件

在你需要导出时把你的实际要导出的数据绑定到这个gridview上，然后把它隐藏掉，到点击导出按钮上在显示，导完就关闭掉，很简单就是visiable=false。

用户根本看不见这个多余的gridview。

2.在页面gridview前边加上

<meta http-equiv="content-type" content="application/ms-excel; charset=UTF-8"/>

我的：

<meta http-equiv="content-type" content="application/ms-excel; charset=UTF-8"/>
