C# Example

Thanks to Juan Herrera for contributing this example.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://html-minifier.com/raw");
request.Method = "POST";
string formContent = "input=" + htmlContent.Text;
byte[] byteArray = Encoding.UTF8.GetBytes(formContent);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byteArray.Length;

Stream str = request.GetRequestStream();
str.Write(byteArray, 0, byteArray.Length);

WebResponse response = request.GetResponse();
str = response.GetResponseStream();
if (str != null)
  StreamReader reader = new StreamReader(str);
  htmlMinified.Text = reader.ReadToEnd();
