public void ExpertControl(System.Web.UI.Control source, DocumentType type)

     }


     else if (type == DocumentType.Word)


     {


         //Word

         Response.ContentType = "application/ms-word";


     }


     Response.Charset = "UTF-8";   


     Response.ContentEncoding = System.Text.Encoding.UTF8;



 


     //关闭控件的视图状态


     source.Page.EnableViewState =false;   



 


     //初始化HtmlWriter


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


     System.Web.UI.HtmlTextWriter htmlWriter = new System.Web.UI.HtmlTextWriter(writer);


     source.RenderControl(htmlWriter);



 


     //输出


     Response.Write(writer.ToString());


     Response.End();


}



 


//文档类型


public enum DocumentType


{


     Word,


     Excel


}

调用方法：

ExpertControl(this, DocumentType.Word);

这是将整个页面导出为Word
