IOC容器

namespace Feng.FramWorkDesign
{
    public class IOCContainer
    {
        private Dictionary<Type, object> mInstance = new Dictionary<Type, object>();

        public void Register<T>(T instance)
        {
            var key = typeof(T);
            if (mInstance.ContainsKey(key))
            {
                mInstance[key] = instance;
            }
            else
            {
                mInstance.Add(key,instance);
            }
        }

        public T Get<T>() where T : class
        {
            var key = typeof(T);
            if (mInstance.TryGetValue(key,out var retInstance))
            {
                return retInstance as T;
            }
            return null;
        }
    }
}

使用方法

namespace Feng.FramWorkDesign
{
    public class IOCExample : MonoBehaviour
    {
        private void Start()
        {
            //创建一个IOC容器
            var container = new IOCContainer();
            
            //注册一个实例
            container.Register(new BluetoothManager());
            
            //根据类型获取实例
            var bluetoothManager = container.Get<BluetoothManager>();
            
            //实现方法
            bluetoothManager.Connect();
        }

        
    }

    public class BluetoothManager
    {
        public void Connect()
        {
            Debug.Log("链接成功");
        }
    }
}
