Performing PING from C#

Most of the users will be doing ping to a system to check whether it is running or responding or not. First thing what they will do is start a command promt and type the ping command. But doing it in C# is also very easy. We can implement in our programs and use to check whether system are responding. It can be used in various network application

public partial class frmPingSystem : Form    
{
    public frmPingSystem()
    {
        InitializeComponent();
    }

    private void pingButton_Click(object sender, EventArgs e)
    {
        int timeout = 12000;
        Ping ping = new Ping();
        byte[] buffer = Encoding.ASCII.GetBytes("ooooooooooooooooooooooo");
        PingOptions options = new PingOptions(64,true);

        AutoResetEvent waiter = new AutoResetEvent(false);
        ping.PingCompleted += new PingCompletedEventHandler(ping_PingCompleted);
        ping.SendAsync(addressTextBox.Text, timeout, buffer, options, null);
    }

    void ping_PingCompleted(object sender, PingCompletedEventArgs e)
    {
        string output = "Status : " + e.Reply.Status.ToString();
        output += "\r\nAddress : " + e.Reply.Address.ToString();
        output += "\r\nRound Trip Time : " + e.Reply.RoundtripTime.ToString();
        output += "\r\nBuffer Length : " + e.Reply.Buffer.Length.ToString();
        output += "\r\nTime to live : " + e.Reply.Options.Ttl.ToString();
        output += "\r\nDont Framment : " + e.Reply.Options.DontFragment.ToString();
        resultTextBox.Text = output;
    }
}

If you want to check the result in the same line where you are sending ping then you must use Send function in place SendAsync

Getting TCP/IP Statistic through C#

Getting the TCP/IP Statistic is very easy through C#. Since all the required methods and properties are there in framework. To get the TCP/IP Statistic we have to use the following nampespace

using System.Net.NetworkInformation;

Now to get the statistic we have to IPGlobalProperties class and extract the information out of it to our TCP/IP statistic object

IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
TcpStatistics tcpstat = null;

now with following line you will get all the details for IPv4

tcpstat = properties.GetTcpIPv4Statistics(); 

and to get the details of IPv6 you use following line

tcpstat = properties.GetTcpIPv6Statistics(); 

now we can get details from this object. Details like data sent, recieved, total connections and various other
