2. Read the text field (this value is every time the user is reaching the page
3. Using the "POST" method, send some values ​​accordingly

   This is my code yet:

     Private zero button 2_Click (Object Sender, EventArgs e) {string URI = "http: //localhost/post.php"; string myParameters = "field = value1 and field2 = value2"; (WebClient wc = new WebClient ()) Tax {string getpage = wc.DownloadString ("http: //localhost/post.php"); MessageBox.Show (getpage); Wc.Headers [HttpRequestHeader.ContentType] = "application / x-www-form-urlencoded"; String HtmlResult = wc.UploadString (URI, so far is pretty good, it is working but it is not entirely that I Here's what I want to achieve. I am able to use the post method, but how do I use GET before sending data? I want to send the data according to the GET result.
