Pinging a network IP or Hostname is not available in Silverlight. But you can do this using WCF service. In this post, I am going to implement the same thing for you.

Introduction

Pinging a network IP or Hostname is not available in Silverlight. But you can do this using WCF service. In this post, I am going to implement the same thing for you. I am using Silverlight 4 here. But this can also be possible in Silverlight 3.

Code of Use

Create a Silverlight application with Silverlight hosting website as “ASP.NET Web Site”:

Now this will create an XAML page for you by default. Add one TextBox and one Button into it. We will use TextBox to enter IP Address or the Hostname and on click of the Button, it will ping that entered IP or Hostname. As a limitation to the Silverlight, you can’t ping directly from the client application. You need to create a WCF service and using that, you can easily ping. Remember there are some limitations here too as you are pinging it from the WCF hosting server.

Let’s implement our WCF service. Create a service method named PingNetwork and pass the hostNameOrAddress as a string. This will be your IP address or the host’s DNS name. Then create an instance of System.Net.NetworkInformation.Ping and pass the required parameter to its “Send” method. This will return you “PingReply”. Now check the Status of the reply. There are several options available. I used only IPStatus.Success to check it and depending upon that, returning true or false.

public bool PingNetwork(string hostNameOrAddress)
{
    bool pingStatus = false;

    using (Ping p = new Ping())
    {
        string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
        byte[] buffer = Encoding.ASCII.GetBytes(data);
        int timeout = 120;

        try
        {
            PingReply reply = p.Send(hostNameOrAddress, timeout, buffer);
            pingStatus = (reply.Status == IPStatus.Success);
        }
        catch (Exception)
        {
            pingStatus = false;
        }
    }

    return pingStatus;
}

Now come to the client side implementation. Add the service reference to the Silverlight application and then call the service method with your IP Address or the DNS name of the host:

client.PingNetworkAsync("google.com");

As it is an asynchronous call, implement the “Completed” event for the method. In the completed event, check the e.Result value. If the server is able to ping, it will return true and in other case, it will return false.

This is a simple implementation of the logic. As told earlier, this will ping from server and not from the client.
