Post Method:
See the below code:

   var request = (HttpWebRequest)WebRequest.Create
                  ("http://idol.talktv.vn/login/check");

    var postData = "act=frm&username=" + user;

    var data = Encoding.ASCII.GetBytes(postData);

    request.Method = "POST";
    request.ContentType = "application/x-www-form-urlencoded";
    request.ContentLength = data.Length;

    using (var stream = request.GetRequestStream())
    {
 stream.Write(data, 0, data.Length);
    }

    var response = (HttpWebResponse)request.GetResponse();
    return new StreamReader(response.GetResponseStream()).ReadToEnd();
}

Get Method:
You can have any below function for do it!

The first function:

public static XmlDocument getXMLDocumentFromXMLTemplate(string inURL)
{
        //Declare an HTTP-specific implementation of the WebRequest class.
 HttpWebRequest myHttpWebRequest = null;     

        //Declare an HTTP-specific implementation of the WebResponse class
 HttpWebResponse myHttpWebResponse = null;

        //Declare XMLResponse document   
 XmlDocument myXMLDocument = null;  

        //Declare XMLReader         
 XmlTextReader myXMLReader = null;           

 try
 {
  //Create Request
  myHttpWebRequest = (HttpWebRequest) HttpWebRequest.Create(inURL);
  myHttpWebRequest.Method = "GET";
  myHttpWebRequest.ContentType = "text/xml; encoding='utf-8'";

  //Get Response
  myHttpWebResponse = 
                       (HttpWebResponse)myHttpWebRequest.GetResponse();

  // Process the data. Now load the XML Document
  myXMLDocument = new XmlDocument();

  //Load response stream into XMLReader
  myXMLReader = new XmlTextReader(
                                myHttpWebResponse.GetResponseStream());
  myXMLDocument.Load(myXMLReader);
 }
 catch (Exception myException)
 {
  throw new Exception("Error Occurred in 
                        AuditAdapter.getXMLDocumentFromXMLTemplate()", myException);
 }
 finally
 {
  myHttpWebRequest = null;
  myHttpWebResponse = null;
  myXMLReader = null;
 }
 return myXMLDocument;
} 

The second function:

private bool getResponeseString(string user)
{
    string sURL = "https://id.zing.vn/v2/uname-suggestion?username=" + 
                                            user + "&cb=zmCore.js998139";

    WebRequest request;
    request = WebRequest.Create(sURL);

    WebProxy myProxy = new WebProxy("myproxy", 80);
    myProxy.BypassProxyOnLocal = true;

    Stream objStream;
    objStream = request.GetResponse().GetResponseStream();
    StreamReader objReader = new StreamReader(objStream);

    return objReader.ReadToEnd();
}
