我有一个c#的职位，它返回我的html。我的职位是检查一个组织名称，并返回与该名称的组织列表。我的问题是，职位返回的html为整个页面，我只想要的组织列表。我认为我应该转换为json，或有其他的可能性？

WebRequest request = WebRequest.Create("http://www.mfinante.ro/numeCod.html");
// Set the Method property of the request to POST.
request.Method = "POST";

// Create POST data and convert it to a byte array.
string postData = "judet=40&name=ORACLE&submit=Vizualizare";
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();
// Display the status.
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.

Console.WriteLine(responseFromServer);
// Clean up the streams.
reader.Close();
dataStream.Close();
response.Close();
