在ASP.NET 2.0中直接得到本页面生成的HTML代码-.NET教程,Asp.Net开发-IDC资讯中心

在asp.net 2.0中，有时候需要对asp.net生成的html代码进行处理，或者是保存成静态文件。asp.net 提供了直接将请求保存成文件的方法：httprequest.saveas方法。下面这个方法就是在asp.net 2.0中得到asp.net生成的html代码，同时，生成一个静态文件的方法。

<%@ page language=“c#“ autoeventwireup=“true“ %>

<!doctype html public “-//w3c//dtd xhtml 1.0 transitional//en”
“http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd”>

    for (int i = 0 ; i < 50 ; i++)
    {
      system.random rd = new system.random(environment.tickcount * i); ;
      dr = dt.newrow();
      dr[0] = “班级“ + i.tostring();
      dr[1] = “【孟子e章】“ + i.tostring();
      dr[2] = system.math.round(rd.nextdouble() * 100, 2);
      dr[3] = system.math.round(rd.nextdouble() * 100, 2);
      dr[4] = system.math.round(rd.nextdouble() * 100, 2);
      dr[5] = system.math.round(rd.nextdouble() * 100, 2);
      dt.rows.add(dr);
    }
    system.data.dataview dv = new system.data.dataview(dt);
    return dv;
  }

  protected void page_load( object sender, eventargs e )
  {
    if (!ispostback)
    {
      gridview1.datasource = createdatasource();
      gridview1.databind();
    }
  }

  protected override void render( htmltextwriter writer )
  {
    system.io.stringwriter html = new system.io.stringwriter();
    system.web.ui.htmltextwriter tw = new system.web.ui.htmltextwriter(html);
    base.render(tw);
    system.io.streamwriter sw;
    sw = new system.io.streamwriter(server.mappath(“a.htm“), false, system.text.encoding.default);
    sw.write(html.tostring());
    sw.close();
    tw.close();
    response.write(html.tostring());
  }
</script>
