asp.net页面如何导出为Word文档？

//This is the Print code as below.

    protected void Button4_Click(object sender, EventArgs e)

    {

        Response.Clear();

        Response.Buffer = true;

        Response.Charset = "GB2312";

       Response.AddHeader("Content-Disposition", "attachment;   filename=" + System.Web.HttpUtility.UrlEncode("中文", System.Text.Encoding.UTF8) + ".xls");//这样的话，可以设置文件名为中文，且文件名不会乱码。其实就是将汉字转换成UTF8      



       // 如果设置为 GetEncoding("GB2312");导出的文件将会出现乱码！

        Response.ContentEncoding = System.Text.Encoding.UTF7;

        Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。 

        System.IO.StringWriter oStringWriter = new System.IO.StringWriter();

        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

        Panel1.RenderControl(oHtmlTextWriter);//Add the Panel into the output Stream.

       //this.GridView1.RenderControl(oHtmlTextWriter);//将gridview输出，你也可以类似的写TextBox1.RenderControl...

        Response.Output.Write(oStringWriter.ToString());//Output the stream.

        Response.Flush();

        Response.End();

    }

    //End of the Print data code.

    

    //重载VerifyRenderingInServerForm方法，否则运行的时候会出现如下错误提示：“类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内”

    public override void VerifyRenderingInServerForm(Control control)

    {

        //override VerifyRenderingInServerForm.

    }

  //重载VerifyRenderingInServerForm方法，否则运行的时候会出现如下错误提示：“类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内”

    public override void VerifyRenderingInServerForm(Control control)

    {

        //override VerifyRenderingInServerForm.

    }
