HttpWebRequest 使用示例：

public partial class Form1 : Form<br /> {<br /> private HttpWebRequest request;<br /> private HttpWebResponse response;</p> <p> public Form1()<br /> {<br /> InitializeComponent();<br /> }</p> <p> private void btnGo_Click(object sender, EventArgs e)<br /> {<br /> try<br /> {<br /> request = (HttpWebRequest)HttpWebRequest.Create(txtUrl.Text);<br /> response = (HttpWebResponse)request.GetResponse();</p> <p> txtResponse.Text="";<br /> txtResponse.Text += "CharacterSet="+response.CharacterSet+"/r/n";<br /> txtResponse.Text += "ContentEncoding=" + response.ContentEncoding + "/r/n";<br /> txtResponse.Text += "ContentType=" + response.ContentType + "/r/n";<br /> txtResponse.Text += "ContentLength=" + response.ContentLength + "/r/n";<br /> txtResponse.Text += "ProtocolVersion=" + response.ProtocolVersion.Major + "." + response.ProtocolVersion.Minor + "/r/n";<br /> txtResponse.Text += "ResponseUri=" + response.ResponseUri.AbsoluteUri + "/r/n";<br /> txtResponse.Text += "Server=" + response.Server + "/r/n";<br /> txtResponse.Text += "StatusDescription=" + response.StatusDescription + "/r/n";<br /> txtResponse.Text += "**********Headers**********/r/n";<br /> //WebHeaderCollection headers=response.Headers;<br /> for(int i=0;i<response.Headers.Count;i++)<br /> {<br /> txtResponse.Text += "/t"+response.Headers.Keys[i]+"=" + response.Headers[i] + "/r/n";<br /> }<br /> txtResponse.Text += "**********Cookies**********/r/n";<br /> for(int i=0;i<response.Cookies.Count;i++)<br /> {<br /> txtResponse.Text += "/tCookies["+i+"]=" + response.Cookies[i] + "/r/n";</p> <p> }<br /> txtResponse.Text += "**********Content**********/r/n";<br /> Stream stream=response.GetResponseStream();<br /> StreamReader readStream = new StreamReader(stream, Encoding.UTF8);<br /> txtResponse.Text += readStream.ReadToEnd();</p> <p> webBrowser.Url = response.ResponseUri;</p> <p> }<br /> catch(System.UriFormatException)<br /> {<br /> txtResponse.Text = "无效的URL";<br /> }<br /> }<br /> }

运行的效果是这样的：
