Pluge模式，是最常见的模式，实现后期绑定。增加程序灵活性，通过配制文件可以方便配制不同的实现。
这篇POST以简单方式实现，代码中细节就不说了。

接口：

namespace SamplePlugePattern.Interface
{
    /// <summary>
    /// define a action interface
    /// </summary>
    public interface IAction
    {
        void Burn();
    }
}

实现:

namespace Machine
{
    public class MachineT50:IAction
    {
        public void Burn()
        {
            Console.WriteLine("MachineT50 is burning now.");
        }
    }
}

客户类：

using System;
using System.Collections.Generic;
using System.Reflection;
using System.Configuration;
using SamplePlugePattern.Interface;

namespace WorkPlat
{
    /// <summary>
    /// Pluge Pattern Sample
    /// </summary>
    /// <remarks>author PetterLiu http://wintersun.cnblogs.com </remarks>
    class Program
    {
        static void Main(string[] args)
        {
            string AssemblyName = ConfigurationManager.AppSettings["AssemblyName"];
            string TypeName = ConfigurationManager.AppSettings["TypeName"];
            IAction action = UsingActivator(AssemblyName, TypeName);
            action.Burn();
        }

        private static IAction UsingCurrentAppDomain(string assemblyname, string typename)
        {
            return AppDomain.CurrentDomain.CreateInstanceAndUnwrap(assemblyname, typename) as IAction;
        }

        private static IAction UsingActivator(string assemblyname, string typename)
        {
            Assembly assembly = Assembly.Load(assemblyname);
            Type type = assembly.GetType(typename);
            return Activator.CreateInstance(type) as IAction;
        }
    }
}

这里使用的是appSettings，实际中还可以用自定义配制节。
