保存登录Cookie并将其用于其他请求

Question

我是新来的c＃。我正尝试使用c＃post请求登录到网站。

此代码是否实际上将cookie保存到CookieContainer，并让它在其他请求中使用此Cookie？我怎么会现在发送一个获取请求与我从登录保存的cookie？

我的主要代码：

private void button1_Click(object sender, EventArgs e) 
{ 
    try 
    { 
     string userName = textBox1.Text; 
     string passWord = textBox2.Text; 
     string postData = "username=" + userName + "&password=" + passWord; 
     string requestUrl = "http://registration.zwinky.com/registration/loginAjax.jhtml"; 

     post botLogin = new post(); 
     botLogin.postToServer (postData ,requestUrl); 
    } 
    catch (Exception ex) 
    { 
     MessageBox.Show("Error :" + ex.Message); 
    } 
} 

我的岗位等级：

public class post 
{ 
    public void postToServer(string postData, string requestUrl) 
    { 
     HttpWebRequest myHttpWebRequest = (HttpWebRequest)HttpWebRequest.Create(requestUrl); 
     myHttpWebRequest.Method = "POST"; 

     byte[] data = Encoding.ASCII.GetBytes(postData); 

     myHttpWebRequest.CookieContainer = new CookieContainer(); 

     myHttpWebRequest.ContentType = "application/x-www-form-urlencoded"; 
     myHttpWebRequest.ContentLength = data.Length; 

     Stream requestStream = myHttpWebRequest.GetRequestStream(); 
     requestStream.Write(data, 0, data.Length); 
     requestStream.Close(); 

     HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse(); 

     Stream responseStream = myHttpWebResponse.GetResponseStream(); 
     StreamReader myStreamReader = new StreamReader(responseStream, Encoding.Default); 

     string pageContent = myStreamReader.ReadToEnd(); 

     myStreamReader.Close(); 
     responseStream.Close(); 

     myHttpWebResponse.Close(); 
     MessageBox.Show(pageContent); 
    } 
}

您需要的请求和响应之间共享的CookieContainer。我有类似的代码目前的工作：

public YourClass 
{ 
    private CookieContainer Cookies; 

    public YourClass() 
    { 
     this.Cookies= new CookieContainer(); 
    } 

    public void SendAndReceive() 
    { 
     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(...); 
     .... 
     request.UserAgent = agent; 
     request.Method = "GET"; 
     request.ContentType = "text/html"; 
     request.CookieContainer = this.Cookies; 
     .... 

     this.Cookies = (HttpWebResponse)request.GetResponse().Cookies; 
    } 
}
