/// <summary>
/// 将Web控件导出
/// </summary>
/// <param name="source">控件实例</param>
/// <param name="type">类型:Excel或Word</param>
public void ExpertControl(System.Web.UI.Control source, DocumentType type)
{
     //设置Http的头信息,编码格式
     if (type == DocumentType.Excel)
     {
         //Excel
         Response.AppendHeader("Content-Disposition","attachment;filename=result.xls");
         Response.ContentType = "application/ms-excel";
     }
     else if (type == DocumentType.Word)
     {
         //Word
         Response.AppendHeader("Content-Disposition","attachment;filename=result.doc");
         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
