輕量級IOC容器IOCFactory發佈。

這是我的第三篇討論IOC工廠的文章了，貌似我已經跟IOC工廠槓上了。

前兩篇是說的造輪子的過程。貌似沒什麼人感興趣，那這次就直接發佈輪子吧。

上圖是 我的容器與 微軟的企業庫 unity的性能比較。

可以看見。效率是微軟企業庫的6倍。

使用依賴注入模式 效率也比微軟企業庫 要快。

目前支持以下幾種模式對象的創建

普通模式，

單例模式，

依賴注入模式，

裝飾模式，

以及單例注入模式

5種模式的獲取方式類似都是採用

Factory.Get<IType>([key])的方式進行獲取。

但是註冊有所不同。

factory.Regist<T, Q>（IOCFactoryModel.InstType.Normal);//普通模式
 factory.Regist<T, Q>(InstType.DI);//依賴注入模式
factory.Regist<T, Q>(InstType.Singleton);//單例模式
factory.RegistDecorate<T, Q>("catDog", "cat");//裝飾者模式
factory.Regist<T, Q>(InstType.DISingleton)//單例注入模式

下面是使用的示例代碼

namespace IOCFactoryUnitTest

    public interface Animal
    {
        string Hawl();
    }
