dotNet抓取页面

上一次有个功能，需要Hompy客户抓取minihome的一个页面。
他们居然说实现不了，晕倒，没办法，只好用.Net写了个demo，
好久没写.Net了，也算温习一下。
很简单的东东，留个记念

using System.Net;
using System.IO;
using System.Text;


    protected void Button1_Click(object sender, EventArgs e)
    {
        String url = this.TextBox1.Text; // eg: http://minihome.sanook.com/minihompy/front/index.html
        HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
        httpWebRequest.Method = "GET";
        HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        if (((int)httpWebResponse.StatusCode) >= 400)
        {
            // error ...
            return;
        }
        Stream responseStream = httpWebResponse.GetResponseStream();
        StreamReader streamReader = new StreamReader(responseStream, Encoding.UTF8);
        String result = streamReader.ReadToEnd().Trim();
        httpWebResponse.Close();
        streamReader.Close();

        // using result....
        this.TextBox2.Text = result;
       
    }
