Castle Windsor Parameters

Just a quick post on how to set required parameters on constructors on registered types. See the following code snippet.

The code below has an EmailService class required two constructor parameters, server and port. These are required to initialize the class. This is where the Parameters method shown below comes in initializing both of these values. Its telling the container what values to assign these values when it has to construct the class.

Hope this helps….


using System.Net.Mail;
using Castle.MicroKernel.Registration;
using Castle.Windsor;

namespace CastleWindsorDemos

    public interface IEmailSender
        void Send(MailMessage message);

    public class EmailSender : IEmailSender
        private readonly string server;
        private readonly int port;

        public EmailSender(string server, int port)
            this.server = server;
            this.port = port;

        public void Send(MailMessage message)
            //Provide detail later

    class Program
        static void Main(string[] args)
            WindsorContainer container = new WindsorContainer();

            IEmailSender sender = container.Resolve<IEmailSender>();

    I know it is confusing (will be addressed in vNext) but don’t use Parameters – use DependsOn.

    See docs here: http://using.castleproject.org/display/IoC/Fluent+Registration+API
