Networking In The Hand includes
the Ping class (In the InTheHand.Net.NetworkInformation namespace). The component
allows you to determine if a network path to a particular host is available and whether
the host is responding. It doesn't guarantee that a particular service is running
on the server (HTTP, FTP etc). You can perform a Ping in a couple of lines of code,
the class has been designed to be an exact subset of the equivalent class in the full
.NET framework. The following is an example of the simplest ping request using a default
payload and timeout settings.
InTheHand.Net.NetworkInformation.Ping
p = new InTheHand.Net.NetworkInformation.Ping();
InTheHand.Net.NetworkInformation.PingReply reply = p.Send("www.google.com");
if (reply.Status
== IPStatus.Success)
{
string message = string.Format("Address:
{0}\r\nRoundTrip time: {1}\r\nTime to live: {2}\r\nDon't fragment: {3}\r\nBuffer size:
{0}",
reply.Address.ToString(),
reply.RoundtripTime,
reply.Options.Ttl,
reply.Options.DontFragment,
reply.Buffer.Length);
MessageBox.Show(message, "Ping");
}
else
{
MessageBox.Show(reply.Status.ToString(), "Ping");
}>
The class allows you to further customise the request. You can specify your own data
payload for example, or set a different timeout value (the default is 5 seconds).
