抽象工厂

1，创建Models

2，创建业务接口IBusinessInterface----添加Models引用

3，创建业务实现BusinessClass1与BusinessClass2(注意：两组中的实现类要同名，但命名空间不可以相同)---添加Models和IBusinessInterface引用

4，创建工厂Factroy

5，Program中添加所有引用

 Models代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Models
{
    public class Car
    {
        public string WheelName { get; set; }
        public string LightName { get; set; }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Models
{
   public class Person
    {
        public string HeadName { get; set; }
        public string EarName { get; set; }
    }
}

        {
            throw new NotImplementedException();
        }

        public void Wheel(int Param1)
        {
            throw new NotImplementedException();

        {
            Person person = new Person { EarName = "耳朵" };
            Console.WriteLine($"我有{Param1}只 { person.EarName}");
        }

        public void Head(int param1)
        {
            throw new NotImplementedException();
        }
    }
}

BusinessClass2代码

using System.Threading.Tasks;

using IBusinessInterface;
using Models;
namespace BusinessClass2
{
    public class CarLogic : ICarLogic
    {
        public void Light(int Param1)
        {
            throw new NotImplementedException();
        }

        public void Wheel(int Param1)
        {
            throw new NotImplementedException();
        }
    }

        {
            throw new NotImplementedException();
        }

        public void Head(int param1)
        {

        }
    }
}

Factroy代码

using System.Threading.Tasks;

using System.Reflection;
using System.Configuration;

namespace Factory
{
    public class ProductsFactory

        private static string Business = ConfigurationManager.AppSettings["Business"];
        public static T GetT<T>(string ClassName)
        {
            return (T) Assembly.Load(Business).CreateInstance(Business+"."+ClassName);
