ASP.NET生成静态方法

CMS系统如果新闻多了，全部生成静态的话。不现实，而且占用空间比较大。那么只生成网站首页是必须的了，下面列出JCMS首页生成静态的方法。换一种思路其实更简单。

当点击生成首页静态的时候。去获取动态首页的源代码，然后在网站根目录生成一个index.htm的文件为静态首页就好了

protected void Button2_Click(object sender, EventArgs e)        {            string asd = GetHtml(""+new JCMS.BLL.Jcms_sysconfig().GetModelByCache(1).Doname+"/index.aspx", "utf-8");            FileStream fs= File.Create(Server.MapPath("~/index.htm"));                               StreamWriter sw = new StreamWriter(fs,Encoding.UTF8);            sw.Write(asd);                           sw.Close();            fs.Close();            Response.Write("<script>alert('操作完成！');location.href='" + Request.Url.AbsoluteUri + "'</script>");            }

这样生成后。看看网站打开是不是飞快了？
