Using the Send method of the Ping class (in System.Net.NetworkInformation namespace) takes the hostname as a parameter. This captures the reply in the PingReply object, as shown below:
//CodePing ping = new Ping();PingReply reply = ping.Send("www.DevX.com");
To determine whether your ping was successful, use the Status property of the PingReply object:
if (reply.Status == IPStatus.Success){ //Success}
