导出execl 出现乱码、请问是哪的问题？

    我电脑上导出没乱码，但是同事的却乱码了！
粘出部分核心代码于2图片，帮忙看看：
page.Response.Clear();
                page.Response.Buffer = true;
                page.Response.Charset = "UTF-8";
                page.Response.ContentEncoding = System.Text.Encoding.UTF8;
                page.Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(filename, Encoding.UTF8) + ".xls");
                page.Response.ContentType = "application/vnd.ms-excel";
                System.IO.StringWriter tw = new System.IO.StringWriter();
                System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(tw);                hw.Write("<html xmlns:x=\"urn:schemas-microsoft-com:office:excel\">");效果图：

试试这个：        Response.Write("<html><head><meta http-equiv=Content-Type content=\"text/html; charset=utf-8\">");
        hw.Write("<html xmlns:x=\"urn:schemas-microsoft-com:office:excel\">");
        Response.Write("</body></html>");
让你同事安装word2003看看，导出在word2007下会出问题

            HttpContext.Current.Response.Close();

            tw.Dispose();
            hw.Dispose();            gvw = null;
            tw = null;
            hw = null;        }
    }
}
用UTF7 或者 GB2312试试吧。我以前跟着个韩国项目，那时Table导出为Excel全部是UTF7，记得韩文中文都不会有问题。
为什么我导出的没有数据呢？？空白的；这是我的代码： Response.Clear();
        Response.Buffer = true;
        Response.Charset = "UTF-8";
        Response.ContentEncoding = System.Text.Encoding.UTF8;
        Response.AddHeader("Content-Disposition", "attachment; filename=" +System.Web.HttpUtility.UrlEncode("ceshi1", System.Text.Encoding.UTF8) + ".xls");
        Response.ContentType = "application/vnd.ms-excel";
        System.IO.StringWriter tw = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(tw);

       // hw.Write("<html xmlns:x=\"urn:schemas-microsoft-com:office:excel\">");
        Response.Write("<html><head><meta http-equiv=Content-Type content=\"text/html; charset=utf-8\">");
        hw.Write("<html xmlns:x=\"urn:schemas-microsoft-com:office:excel\">");
        Response.Write("</body></html>");
好多年写的类

有例子，以后生成excel很简单。不必那么写。
作为一个好的程序员，想的是：一切都应该被重用。
