GridView导出Excel与Word

ASP.NET 2.0,C#----利用GridView控件导出其他文件（导出Excel，导出Word文件）

// 注意，在Visual Studio2005平台下，如果使用GridView导出文件，就必须重载VerifyRenderingInServerForm方法， 可以无内容，但必须写

        public override void VerifyRenderingInServerForm(Control control)

        {

        }

 

    /// <summary>
    ///  导出到文件的方法，
    /// </summary>
    /// <param name="Model">Model=1:导出为Execl，Model=2:导出为Word</param>
    private void toFiles(int Model)
    {
        //将DataGrid的数据导出到Excel

        string strFileName = this.txtCond.Text.Trim();
        System.Web.HttpContext HC = System.Web.HttpContext.Current;
        HC.Response.Clear();
        HC.Response.Buffer = true;
        HC.Response.Charset = "GB2312";
        //page.Response.Charset = "UTF-8";
        HC.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");   //设置输出流为简体中文

        if (Model == 1)
        {
            //---导出为Excel文件
            HC.Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(strFileName, System.Text.Encoding.UTF8) + ".xls");
            HC.Response.ContentType = "application/ms-excel";    //设置输出文件类型为excel文件。
        }

        else
        {
            //--- 导出为Word文件
            HC.Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(strFileName, System.Text.Encoding.UTF8) + ".doc");
            HC.Response.ContentType = "application/ms-word";   //设置输出文件类型为Word文件。
        }
        this.Page.EnableViewState = false;
        System.IO.StringWriter sw = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter htw = new System.Web.UI.HtmlTextWriter(sw);
        this.GridView1.RenderControl(htw);
        HC.Response.Write(sw.ToString());
        HC.Response.End();
    }

    protected void btnExcel_Click(object sender, EventArgs e)
    {
        toFiles(1);
    }
    protected void btnWord_Click(object sender, EventArgs e)
