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

Declare string address and int port and you are ready to connect through the TcpClient class.

System.Net.Sockets.TcpClient client = new TcpClient();
try
{
    client.Connect(address, port);
    Console.WriteLine("Connection open, host active");
} catch (SocketException ex)
{
    Console.WriteLine("Connection could not be established due to: \n" + ex.Message);
}
finally
{
    client.Close();
}
