导出EXCEL出现乱码，帮帮忙

Question

使用了网上的方法导出EXCEL：
    protected void bt_excel_Click(object sender, EventArgs e)
    {
        if (gd_data.Rows.Count > 0)
        {
            //调用导出方法  
            ExportGridViewForUTF8(gd_data, DateTime.Now.ToShortDateString() + ".xls");
        }
        else
        {
            Response.Write("<script  language='javascript'>alert('查询的数据为空！')</script>");
        }    }
    private void ExportGridViewForUTF8(GridView GridView, string filename)
    {
        string attachment = "attachment; filename=" + filename;
        Response.ClearContent();
        Response.Buffer = true;
        Response.AddHeader("content-disposition", attachment);
        Response.Charset = "UTF-8";
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");
        Response.ContentType = "application/ms-excel";
        System.IO.StringWriter sw = new System.IO.StringWriter();
        HtmlTextWriter htw = new HtmlTextWriter(sw);
        GridView.RenderControl(htw);
        Response.Output.Write(sw.ToString());
        Response.Flush();
        Response.End();    }
    public override void VerifyRenderingInServerForm(Control control)
    {    }

换其他编码方式看看
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
