How can I test a connection to a server with C# given the server's IP address?

Question

How can I programmatically determine if I have access to a server with a given IP address using C#?

Answer 1

You could use the Ping class (.NET 2.0 and above)

    Ping x = new Ping();
    PingReply reply = x.Send(IPAddress.Parse("127.0.0.1"));

    if(reply.Status == IPStatus.Success)
        Console.WriteLine("Address is accessible");

You might want to use the asynchronous methods in a production system to allow cancelling, etc.
