Send Ping Command in C#

I had a scenario which need to test  whether server available or not for my application.So i wrote following code to accomplish that.

.net framework has set of classes which support to Ping to the specified host.

public bool IsAvailableHost(string hostName)
{
   var ping = new Ping();
   try
   {
      PingReply reply = ping.Send(hostName);
      return reply != null && reply.Status == IPStatus.Success;
   }
   catch (Exception ex)
   {
     throw ex;
   }
}
