using System;
public class Demo {
   public static void Main(){
      string strURI = "http://localhost";
      Console.WriteLine("URI = "+strURI);
      UriHostNameType res = Uri.CheckHostName(strURI);
      Console.WriteLine("Host type = "+res);
   }
}

public class Demo {
   public static void Main(){
      string strURI = "www.tutorialspoint.com";
      Console.WriteLine("URI = "+strURI);
      UriHostNameType res = Uri.CheckHostName(strURI);
