如何在csharp上提交后获得响应页面？

Question

在远程网站上有一个页面，用户可以在表单中输入输入值，单击按钮并以输出形式得到结果。 我想发送一个请求到页面，填写必要的输入表单，提交并获得一个结果页面，输出表格填写。

主题类似的所有线程给出代码样本是这样的：

// Create a request using a URL that can receive a post. 
      WebRequest request = WebRequest.Create("http://www.site.com"); 
      // Set the Method property of the request to POST. 
      request.Method = "POST"; 
      // Create POST data and convert it to a byte array. 
      string postData = string.Format("inputParam=value"); 
      byte[] byteArray = Encoding.UTF8.GetBytes(postData); 
      // Set the ContentType property of the WebRequest. 
      request.ContentType = "application/x-www-form-urlencoded"; 
      // Set the ContentLength property of the WebRequest. 
      request.ContentLength = byteArray.Length; 
      // Get the request stream. 
      Stream dataStream = request.GetRequestStream(); 
      // Write the data to the request stream. 
      dataStream.Write(byteArray, 0, byteArray.Length); 
      // Close the Stream object. 
      dataStream.Close(); 
      // Get the response. 
      WebResponse response = request.GetResponse(); 
      // Get the stream containing content returned by the server. 
      dataStream = response.GetResponseStream(); 

      response.Close(); 

它返回一个页面，填写输入形式，但输出领域仍是空白，就像它不会做一个提交按钮的点击。

如何从我的C＃代码执行提交并接收带有输出数据的html文档？

将webresponse部分更改为以下内容;

WebResponse response = request.GetResponse();     
    dataStream = response.GetResponseStream(); 
    StreamReader reader = new StreamReader (dataStream); 
    string responseFromServer = reader.ReadToEnd();
