用gridView 绑定数据后导出word文档

protected void btnWord_Click(object sender, EventArgs e)
{
GridView1.AllowPaging = false;//清楚分页
GridView_BindByDate();
Response.Clear();
Response.BufferOutput = true;
//设定输出的字符集
Response.Charset = "GB2312";
//假定导出的文件名为FileName.doc
Response.AppendHeader("Content-Disposition", "attachment;filename=FileName.doc");
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
////设置导出文件的格式
Response.ContentType = "application/ms-word";
//关闭ViewState
this.EnableViewState = false;
CultureInfo cultureInfo = new CultureInfo("ZH-CN", true);
StringWriter stringWriter = new StringWriter(cultureInfo);
HtmlTextWriter textWriter = new HtmlTextWriter(stringWriter);
GridView1.RenderControl(textWriter);
////把HTML写回浏览器
Response.Write(stringWriter.ToString());
Response.Flush();
Response.End();
//恢复分页
GridView1.AllowPaging = true;
//为GridView重新绑定数据源
GridView_BindByDate();

}
导出word文档后中文不能正常显示，解决方法如下：

在上文红色行后加上

Response.Write("<meta http-equiv=Content-Type content=\"text/html; charset=GB2312\">");
