用于远程调用Windows服务方法的体系结构

我已经向我的Windows服务添加了远程处理调用,这样我的GUI应用程序就可以与之对话。它工作得很好,但是我的渠道实现对我的服务一无所知。

我应该如何分层我的类,以便我的远程处理通道实现可以调用我的服务类中的方法?

通道接口:

public interface IMyService
{
    string Ping();
    string SomeMethod(string input);
}

渠道实施:

public class MyServiceChannel : MarshalByRefObject, IMyService
{
    public string Ping()
    {
        return "Pong";
    }

    public string SomeMethod(string input)
    {
        MethodForChannelToCall(input); // in Service class. How to reference?
        return "Some Output";
    }
}

class MyService : ServiceBase
{
    public void MethodForChannelToCall(string input)
    {
        // do service stuff for remoting call
    }

    public MyService()
    {
        // Set up remoting channel
        try
        {
            TcpChannel tcpChannel = new TcpChannel(12345);
            ChannelServices.RegisterChannel(tcpChannel, false);

            RemotingConfiguration.RegisterWellKnownServiceType(
                typeof(MyServiceChannel),
                "MyServiceChannel",
                WellKnownObjectMode.SingleCall);

            // Should I pass an instance of my service to my channel somehow here?
        }
        catch (Exception ex)
        {
            this.EventLog.WriteEntry("Remoting error: " + ex.ToString());
        }
    }
}

我应该如何构造我的类,以便我的频道可以调用我的服务方法?
