HttpWebRequest虚拟按钮单击

我有我的html-php网页，包含表单，输入和sumbit按钮。 使用html请求我试图填写一些字段并按下按钮，但我不能。 这是C＃代码：

public static string PostData(string data) { HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost/request.php"); //http://businesslist.com/search/clients/?m=userspace&d=addclassified request.Method = "POST"; request.AllowAutoRedirect = true; request.ContentType = "application/x-www-form-urlencoded"; byte[] EncodedPostParams = Encoding.UTF8.GetBytes(data); request.ContentLength = EncodedPostParams.Length; request.GetRequestStream().Write(EncodedPostParams, 0, EncodedPostParams.Length); request.GetRequestStream().Close(); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); string str = new StreamReader(response.GetResponseStream(), Encoding.UTF8).ReadToEnd(); return str; } static void Main(string[] args) { string data = PostData("name=" + HttpUtility.UrlEncode("lol") + "&btn=Clicked"); Console.WriteLine(data); Console.ReadLine(); } 

和2个php文件：request.php

      
    Select State/Country Select 1 Select 2   
   

response.php

这是我网站的链接

那么，我怎么能按这个按钮？

我在LINQPad中试过这个并且它有效：

 void Main() { var request = (HttpWebRequest)WebRequest.Create("http://128.75.49.209/response.php"); request.Method = WebRequestMethods.Http.Post; request.ContentType = "application/x-www-form-urlencoded"; using (var stream = request.GetRequestStream()) { var buffer = Encoding.UTF8.GetBytes("name=asd&pass=asd&country=82&btn=Submit+Query"); stream.Write(buffer,0,buffer.Length); } var response = (HttpWebResponse)request.GetResponse(); string result = String.Empty; using (var reader = new StreamReader( response.GetResponseStream())) { result = reader.ReadToEnd(); } Console.WriteLine(result); } 

问题是您在代码中使用了request.php而不是response.php 。
