System.Net.NetworkInformation Ad Alanı, ihtiyacınız olan şeydir. Bu link fazla ayrıntı

public static string PingHost(string host) 
{ 
    //string to hold our return messge 
    string returnMessage = string.Empty; 

    //IPAddress instance for holding the returned host 
    IPAddress address = GetIpFromHost(ref host); 

    //set the ping options, TTL 128 
    PingOptions pingOptions = new PingOptions(128, true); 

    //create a new ping instance 
    Ping ping = new Ping(); 

    //32 byte buffer (create empty) 
    byte[] buffer = new byte[32]; 

    //first make sure we actually have an internet connection 
    if (HasConnection()) 
    { 
     //here we will ping the host 4 times (standard) 
     for (int i = 0; i < 4; i++) 
     { 
      try 
      { 
       //send the ping 4 times to the host and record the returned data. 
       //The Send() method expects 4 items: 
       //1) The IPAddress we are pinging 
       //2) The timeout value 
       //3) A buffer (our byte array) 
       //4) PingOptions 
       PingReply pingReply = ping.Send(address, 1000, buffer, pingOptions); 

       //make sure we dont have a null reply 
       if (!(pingReply == null)) 
       { 
        switch (pingReply.Status) 
        { 
         case IPStatus.Success: 
          returnMessage = string.Format("Reply from {0}: bytes={1} time={2}ms TTL={3}", pingReply.Address, pingReply.Buffer.Length, pingReply.RoundtripTime, pingReply.Options.Ttl); 
          break; 
         case IPStatus.TimedOut: 
          returnMessage = "Connection has timed out..."; 
          break; 
         default: 
          returnMessage = string.Format("Ping failed: {0}", pingReply.Status.ToString()); 
          break; 
        } 
       } 
       else 
        returnMessage = "Connection failed for an unknown reason..."; 
      } 
      catch (PingException ex) 
      { 
       returnMessage = string.Format("Connection Error: {0}", ex.Message); 
      } 
      catch (SocketException ex) 
      { 
       returnMessage = string.Format("Connection Error: {0}", ex.Message); 
      } 
     } 
    } 
    else 
     returnMessage = "No Internet connection found..."; 

    //return the message 
    return returnMessage; 
}
