C#发送简单的HTTPPOST请求给传统的ASP网页。

//用自己制作的网页都可以，这里用百度做例子。
string url="http://www.baidu.com";   
string data ="inputBox1=orange";
byte[] buffer = Encoding.ASCII.GetBytes(data);

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.Method="POST";
req.COntenType="application/x-www-form-urlencoded";
req.COntenLength=buffer.Length;

Stream reqst = req.GetRequestStream();
reqst.Write(buffer,0,buffer.Length);
reqst.Flush();
reqst.Close();

Console.WriteLine("\nGrabbing‘orange‘");
HttpWebResponse res = (HttpWebResponse)req.GetResponse();
Stream resst = res.GetResponseStream();
StreamReader sr = new StreamReader(resst);

Console.WriteLine("\nGrabbing HTTP response\n");
Console.WtiteLine(sr.ReadToEnd());
sr.Close();
resst.Close();
Console.WriteLine("Done");
