Asp.net的post提交方式

//建立WebRequest对象，url目标地址
HttpWebRequest req =(HttpWebRequest)WebRequest.Create(url);

//将LoginInfo转换为byte[]格式，这里的LoginInfo应该是你要传输的数据
byte[] requestBytes = System.Text.Encoding.ASCII.GetBytes(LoginInfo);

//设置请求为POST方式,
req.Method = "POST";

//设置请求类型
req.ContentType = "application/x-www-form-urlencoded";

//请求发送的数据长度, 这里就很清楚了，请求数据是从LoginInfo转换来的
//前面的代码byte[] requestBytes = System.Text.Encoding.ASCII.GetBytes(LoginInfo);
req.ContentLength =  requestBytes.Length;

//建立请求的输入流
Stream requestStream = req.GetRequestStream();

//从requestBytes中读取数据到输入流中
requestStream.Write(requestBytes, 0, requestBytes.Length);

//关闭输入流
requestStream.Close();

//获取响应对象
HttpWebResponse res = (HttpWebResponse)req.GetResponse();

//获取服务器返回流
StreamReader sr = new StreamReader(res.GetResponseStream(),System.Text.Encoding.Default);

//读取返回流数据，并赋值给backstr 
string backstr =sr.ReadToEnd();

//页面输出backstr
Response.Write(backstr);

//关闭* 
sr.Close();
res.Close();
