C# ICMP Echo example

IcmpEchoSample.cs

// Add a reference to (and using) System.Net.NetworkInformation  
string addressOrIp = "127.0.0.1";

Ping ping = new Ping();
PingReply reply = ping.Send(addressOrIp);
if (reply.Status == IPStatus.Success)
{
 Console.WriteLine ("Address: {0}", reply.Address.ToString ());
 Console.WriteLine ("RoundTrip time: {0}", reply.RoundtripTime);
 Console.WriteLine ("Time to live: {0}", reply.Options.Ttl);
 Console.WriteLine ("Don't fragment: {0}", reply.Options.DontFragment);
 Console.WriteLine ("Buffer size: {0}", reply.Buffer.Length);
}
else
{
 Console.WriteLine (reply.Status);
}  

It does not work well in case ping fails. Unhandled exception error pops up. even with catch and try it works but it slows down an application.
