C# 獲取DLL中需要的接口類

[ 需求 ]

使用反射，循環本地DLL文件，獲取實現了所需接口的類，並實例化。

Loop local dll files by reflection library and assembly library to find all the classes that implement certain interface and create instances for them.

二話不說，先上代碼。

Talk is cheap. Show me the code.

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Reflection;

namespace InterfaceClassLoader
{
    public class Loader
    {

        private List<IMyInterface> myInstanceList;
        private void Initialize()
        {

            try
            {
                var type= typeof(IMyInterface);
                myInstanceList= GetAllAssemblies().
                    SelectMany(a => a.GetTypes()).
                    Where(t => !t.IsInterface && type.IsAssignableFrom(t)).
                    Select(t => (IMyInterface)Activator.CreateInstance(t)).ToList();
            }
            catch (Exception ex)
            {}
        }


        private List<Assembly> GetAllAssemblies()
        {
            var folderPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
            var allAssemblies = new List<Assembly>();
            Directory.GetFiles(folderPath,"*.dll").ToList().ForEach(f => 
            {
                allAssemblies.Add(Assembly.LoadFile(f));
            });


            var filteredAssembly = allAssemblies.FindAll(a => a.FullName.Contains("MyMark"));
            return filteredAssembly;
        }

    }      

}
