最简单的静态页生成，好用，实用

 protected void Page_Load(object sender, EventArgs e)
    {
        //要生成html页面的aspx页面
        string url = @"http://www.mamogu.com/index.asp";
        //html页面文件名

        string fna = Server.MapPath("html/index.html");
        if (CreateList(url, fna))
        {
            Response.Write("<p>生成首页成功：" + fna);
        }

}

 //静态页生成方法 

private bool CreateList(string url, string fna)
{
bool ok;
//准备生成
string strHtml;
StreamReader sr = null; //用来读取流

StreamWriter sw = null; //用来写文件
Encoding code = Encoding.GetEncoding("utf-8"); //定义编码 
//构造web请求，发送请求，获取响应
WebRequest HttpWebRequest = null;
WebResponse HttpWebResponse = null;
HttpWebRequest = WebRequest.Create(url);
HttpWebResponse = HttpWebRequest.GetResponse();

//获得流

sr = new StreamReader(HttpWebResponse.GetResponseStream(), code);
strHtml = sr.ReadToEnd();

//写入文件
try
{
sw = new StreamWriter(fna, false, code);
sw.Write(strHtml);
sw.Flush();
ok = true;
}
catch (Exception ex)
{
HttpContext.Current.Response.Write("<p>写入文件出错：" + ex.Message);
HttpContext.Current.Response.End();
ok = false;
}
finally
{
sw.Close();
}
return ok;
}
