HttpWebRequest

HttpWebRequest get 方式取得网页内容

 //url: http://www.programfan.com/club/showpost.asp?id=12156
        string url = this.TextBox1.Text.ToString();
        HttpWebRequest webReques = (HttpWebRequest)HttpWebRequest.Create(url);
        webReques.Method = "GET";
        
        HttpWebResponse webRespon = (HttpWebResponse)webReques.GetResponse();
        System.IO.Stream newstream = webRespon.GetResponseStream();
        System.IO.StreamReader srRead = new System.IO.StreamReader(newstream, System.Text.Encoding.Default);
        string outString=srRead.ReadToEnd();
        this.TextBox2.Text = outString;        
        srRead.Close();         

HttpWebRequest  post 方式取得网页内容(还有待修改)

 CookieContainer cookieContain = new CookieContainer();
        

        string url = this.TextBox1.Text.ToString();
        HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url);
        httpWebRequest.Method = "POST";
        httpWebRequest.ContentType = "application/x-www-form-urlencoded";

        byte[] setStr = System.Text.Encoding.Default.GetBytes("txtEmployeeCode=10004194&txtPassword=10004194");
        httpWebRequest.ContentLength = setStr.Length;
        httpWebRequest.CookieContainer = cookieContain;


        System.IO.Stream s = httpWebRequest.GetRequestStream();
        s.Write(setStr, 0, setStr.Length);
        s.Close();

        HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        System.IO.StreamReader sr = new System.IO.StreamReader(httpWebResponse.GetResponseStream(), System.Text.Encoding.Default);
        string outPut = sr.ReadToEnd();
        //this.TextBox2.Text = outPut;
        sr.Close();
        Response.Write(outPut);
