C# HttpWebRequest 使用，一个Http分析Demo

HttpWebRequest 使用示例：

    public partial class Form1 : Form
    {
        private HttpWebRequest request;
        private HttpWebResponse response;

        public Form1()
        {
            InitializeComponent();
        }

        private void btnGo_Click(object sender, EventArgs e)
        {
            try
            {
                request = (HttpWebRequest)HttpWebRequest.Create(txtUrl.Text);
                response = (HttpWebResponse)request.GetResponse();

                txtResponse.Text="";
                txtResponse.Text += "CharacterSet="+response.CharacterSet+"/r/n";
                txtResponse.Text += "ContentEncoding=" + response.ContentEncoding + "/r/n";
                txtResponse.Text += "ContentType=" + response.ContentType + "/r/n";
                txtResponse.Text += "ContentLength=" + response.ContentLength + "/r/n";
                txtResponse.Text += "ProtocolVersion=" + response.ProtocolVersion.Major + "." + response.ProtocolVersion.Minor + "/r/n";
                txtResponse.Text += "ResponseUri=" + response.ResponseUri.AbsoluteUri + "/r/n";
                txtResponse.Text += "Server=" + response.Server + "/r/n";
                txtResponse.Text += "StatusDescription=" + response.StatusDescription + "/r/n";
                txtResponse.Text += "**********Headers**********/r/n";
                //WebHeaderCollection headers=response.Headers;
                for(int i=0;i<response.Headers.Count;i++)
                {
                    txtResponse.Text += "/t"+response.Headers.Keys[i]+"=" + response.Headers[i] + "/r/n";
                }
                txtResponse.Text += "**********Cookies**********/r/n";  
                for(int i=0;i<response.Cookies.Count;i++)
                {
                    txtResponse.Text += "/tCookies["+i+"]=" + response.Cookies[i] + "/r/n";
                    
                }
                txtResponse.Text += "**********Content**********/r/n";
                Stream stream=response.GetResponseStream();
                StreamReader readStream = new StreamReader(stream, Encoding.UTF8);
                txtResponse.Text += readStream.ReadToEnd();

                webBrowser.Url = response.ResponseUri;

            }
            catch(System.UriFormatException)
            {
                txtResponse.Text = "无效的URL";
            }    
        }
    }

　　

运行的效果是这样的：
