How to Ping with C Sharp?
C# Ping Code
I will explain how to ping any computer to any site with c sharp. We will use System.Net.NetworkInformation and System.Net library in c sharp for this event. With these libraries, we can easily ping a site or computer we want.
If we look at our codes that we will use in the btn_click event, we do not forget to add System.Net.NetworkInformation and System.Net namespace to our project.
protected void Btn_Click(object sender, EventArgs e)
{
Ping p = new Ping(); PingReply sonuc = p.Send(Txtip.Text);
if (sonuc.Status == IPStatus.Success)
{
lblsonuc.Text += sonuc.Address.ToString() + "";
lblsonuc.Text += sonuc.RoundtripTime.ToString() + "";
lblsonuc.Text += sonuc.Options.Ttl.ToString() + "";
}
else if (sonuc.Status == IPStatus.TimedOut)
{
lblsonuc.Text = ("Time out.");
}
}In this way, we have solved the pinging thing in a simple sense. I use it to check whether my servers are online or not. Of course, I changed it a bit. The page “post-back” every 5 seconds, i.e. refresh, allows me to get updated information about our servers. It worked very successfully.
I will share an example of a console application for a wider example:
using System;
using System.Net;
using System.Net.NetworkInformation;
using System.Text;
namespace Examples.System.Net.NetworkInformation.PingTest
{
public class PingExample
{
// args[0] can be an IPaddress or host name.
public static void Main (string[] args)
{
Ping pingSender = new Ping ();
PingOptions options = new PingOptions ();
// Use the default Ttl value which is 128,
// but change the fragmentation behavior.
options.DontFragment = true;
// Create a buffer of 32 bytes of data to be transmitted.
string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
byte[] buffer = Encoding.ASCII.GetBytes (data);
int timeout = 120;
PingReply reply = pingSender.Send (args[0], timeout, buffer, options);
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);
}
}
}
}
