  Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");//设置输出流为简体中文
  Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。 
  this.EnableViewState = false;    
  System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true);
  System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad); 
  System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
  this.dgList.RenderControl(oHtmlTextWriter); 
  Response.Write(oStringWriter.ToString());
  Response.End();

   Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");//设置输出流为简体中文
   Response.ContentType = "application/ms-word";//设置输出文件类型为word文件。 
   this.EnableViewState = false;    
   System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN",true);
   System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad); 
   System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
   this.dgList.RenderControl(oHtmlTextWriter); 
   Response.Write(oStringWriter.ToString());
