原来代码
private static void writetoexcelfromdatagrid(datagrid dg, string filename)
{
//stringwriter tw = new stringwriter(new cultureinfo( "zh-chs", false));
stringwriter tw = new stringwriter();
htmltextwriter hw = new htmltextwriter(tw);
dg.rendercontrol(hw);
system.web.httpresponse response = system.web.httpcontext.current.response;
response.clear();
response.contentencoding=system.text.encoding.getencoding("utf-8");
response.contenttype ="application/vnd.ms-excel";
response.addheader("content-disposition", "attachment; filename=" + filename);
response.charset = "gb2312";
response.write(tw.tostring());
response.end();
}
正确
response.contentencoding=system.text.encoding.getencoding("utf-7");
原因 utf-8不支持中文
