提交Html请求并保存身份信息

// 创建请求
HttpWebRequest mRequest  =  WebRequest.Create("http://www.a.com /Login.aspx " )  as  HttpWebRequest;
mRequest.Method  =   " POST " ;
mRequest.ContentType  =   " application/x-www-form-urlencoded " ;
mRequest.AllowAutoRedirect  =   false ;
mRequest.CookieContainer  =   new  CookieContainer();

string  strPostData  =  "username=aaa&userpwd=bbb";
byte [] buffer  =  System.Text.Encoding.UTF8.GetBytes(strPostData);
mRequest.ContentLength  =  buffer.Length;

// 发送数据
Stream stream  =  mRequest.GetRequestStream();
stream.Write(buffer,  0 , buffer.Length);
stream.Close();

// 得到响应
wr  =  (HttpWebResponse)mRequest.GetResponse();
CookieCollection cc  =  mRequest.CookieContainer.GetCookies(mRequest.Address);

// 读取响应内容
sr  =   new  StreamReader(wr.GetResponseStream(), System.Text.Encoding.GetEncoding( " gb2312 " ));

// 显示在浏览器中
browser.Navigate( " about:blank " );
browser.DocumentText  =  sr.ReadToEnd();

// 关闭
sr.Close();
wr.Close();

再次提交时，将cc加入到请求对象的CookieContainer中。
