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         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)         {             string strFileName = DateTime.Now.ToString("yyyyMMdd-hhmmss");             System.Web.HttpContext HC = System.Web.HttpContext.Current;              HC.Response.Clear();              HC.Response.Buffer = true;              HC.Response.ContentEncoding = System.Text.Encoding.UTF8;//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。             }               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();                    }         //-导出为Excel文件         protected void ToExecl_Click(object sender, EventArgs e)         {             toFiles(1);         }         //-导出为Word文件         protected void Button1_Click(object sender, EventArgs e)         {             toFiles(2);         }
