Kullanarak ping in C#

Question

Uzak bir sistemi pencereli bir pencereye ping ettiğimde yanıt olmadığını, ancak c ile ping yaptığımda başarı diyor. Windows doğru, cihaz bağlı değil. Windows'umda kodum neden başarılı bir şekilde ping yapabiliyor?

Ping p1 = new Ping(); 
PingReply PR = p1.Send("192.168.2.18"); 
// check when the ping is not success 
while (!PR.Status.ToString().Equals("Success")) 
{ 
    Console.WriteLine(PR.Status.ToString()); 
    PR = p1.Send("192.168.2.18"); 
} 
// check after the ping is n success 
while (PR.Status.ToString().Equals("Success")) 
{ 
    Console.WriteLine(PR.Status.ToString()); 
    PR = p1.Send("192.168.2.18"); 
}

using System.Net.NetworkInformation;  

public static bool PingHost(string nameOrAddress) 
{ 
    bool pingable = false; 
    Ping pinger = new Ping(); 
    try 
    { 
     PingReply reply = pinger.Send(nameOrAddress); 
     pingable = reply.Status == IPStatus.Success; 
    } 
    catch (PingException) 
    { 
     // Discard PingExceptions and return false; 
    } 
    return pingable; 
}

using System.Net.NetworkInformation; 

    namespace PingTest1 
    { 
     public partial class Form1 : Form 
     { 
      public Form1() 
      { 
       InitializeComponent(); 
      } 

      private void button1_Click(object sender, EventArgs e) 
      { 
       Ping p = new Ping(); 
       PingReply r; 
       string s; 
       s = textBox1.Text; 
       r = p.Send(s); 

       if (r.Status == IPStatus.Success) 
       { 
        lblResult.Text = "Ping to " + s.ToString() + "[" + r.Address.ToString() + "]" + " Successful" 
         + " Response delay = " + r.RoundtripTime.ToString() + " ms" + "\n"; 
       } 
      } 

      private void textBox1_Validated(object sender, EventArgs e) 
      { 
       if (string.IsNullOrWhiteSpace(textBox1.Text) || textBox1.Text == "") 
       { 
        MessageBox.Show("Please use valid IP or web address!!"); 
       } 
      } 
     }
