IOC容器特性注入第四篇：容器初始化

IOC容器，就是把各种服务都注入到容器里，想要什么就去拿什么，不仅解决服务类和接口类的耦合度还可以提高性能方便管理。

这里封装一个接口类和一个实现类

1.IContainerManager接口

    public interface IContainerManger : IDisposable {//#region AddResolvingObserver//void AddResolvingObserver(IResolvingObserver observer);//#endregion#region AddComponentvoid AddComponent<TService>(string key = "", ComponentLifeStyle lifeStyle = ComponentLifeStyle.Singleton);void AddComponent(Type type, string key = "", ComponentLifeStyle liftStyle = ComponentLifeStyle.Singleton);void AddComponent<TService, TImplementation>(string key = "",ComponentLifeStyle liftStyle = ComponentLifeStyle.Singleton);void AddComponent(Type service, Type implementation, string key = "",ComponentLifeStyle liftStyle = ComponentLifeStyle.Singleton, params  Parameter[] parameters);void AddComponentInstance<TService>(object instance, string key = "");void AddComponentInstance(object instance, string key = "");void AddComponentInstance(Type service, object instance, string key = "");#endregion#region ResolveT Resolve<T>(string key = "", params Parameter[] parameters) where T : class;object Resolve(Type type, string key = "", params Parameter[] parameters);#endregion#region ResolveAllT[] ResolveAll<T>(string key = "");object[] ResolveAll(Type type, string key = "");#endregion#region TryResolveT TryResolve<T>(string key = "", params Parameter[] parameters);object TryResolve(Type type, string key = "", params Parameter[] parameters);#endregion#region ResolveUnRgeistered(未注册) T ResolveUnregistered<T>() where T : class;object ResolveUnregistered(Type type);#endregion}

也是一样，实例版本和泛型版本都写了，方便使用　

2. ContainerManager实现类

    public class ContainerManager : StandardKernel, IContainerManger {#region Fieldsprivate IKernel _container;#endregion#region .ctorpublic ContainerManager() {_container = new StandardKernel();_container.Settings.Set("InjectAttribute", typeof(DaHua.Common.Runtime.Dependency.InjectAttribute));}#endregion#region Propertiespublic IKernel Container {get {return _container;}}#endregion#region AddComponentpublic void AddComponent<TService>(string key = "", ComponentLifeStyle lifeStyle = ComponentLifeStyle.Singleton) {AddComponent(typeof(TService), typeof(TService), key, lifeStyle);}public void AddComponent(Type type, string key = "", ComponentLifeStyle liftStyle = ComponentLifeStyle.Singleton) {AddComponent(type, type, key, liftStyle);}public void AddComponent<TService, TImplementation>(string key = "", ComponentLifeStyle liftStyle = ComponentLifeStyle.Singleton) {AddComponent(typeof(TService), typeof(TImplementation), key, liftStyle);}public void AddComponent(Type service, Type implementation, string key = "", ComponentLifeStyle liftStyle = ComponentLifeStyle.Singleton, params  Parameter[] parameters) {var binding = _container.Bind(service).To(implementation);if (parameters != null) {var ninjectParameter = ConvertParameters(parameters);foreach (var parameter in ninjectParameter) {binding.WithParameter(parameter);}}binding.PerLifeStyle(liftStyle).MapKey(key).ReplaceExsting(service);}#endregion#region AddComponentInstancepublic void AddComponentInstance<TService>(object instance, string key = "") {AddComponentInstance(typeof(TService), instance, key);}public void AddComponentInstance(object instance, string key = "") {AddComponentInstance(instance.GetType(), instance, key);}public void AddComponentInstance(Type service, object instance, string key = "") {_container.Bind(service).ToConstant(instance).MapKey(key).ReplaceExsting(service);}#endregion#region ConvertParametersprivate static NinjectParameters.IParameter[] ConvertParameters(Parameter[] parameters) {if (parameters == null) {return null;}returnparameters.Select(it => new NinjectParameters.ConstructorArgument(it.Name, (context) => it.valueCallback())).ToArray();}#endregion#region Resolvepublic virtual T Resolve<T>(string key = "", params Parameter[] parameters) where T : class {if (string.IsNullOrWhiteSpace(key)) {return _container.Get<T>(ConvertParameters(parameters));}return _container.Get<T>(key, ConvertParameters(parameters));}public virtual object Resolve(Type type, string key = "", params Common.Runtime.Parameter[] parameters) {if (string.IsNullOrWhiteSpace(key)){return _container.Get(type, ConvertParameters(parameters));}return _container.Get(type, key, ConvertParameters(parameters));}#endregion#region ResolveAllpublic virtual T[] ResolveAll<T>(string key = "") {if (string.IsNullOrWhiteSpace(key)){return _container.GetAll<T>().ToArray();}return _container.GetAll<T>(key).ToArray();}public virtual object[] ResolveAll(Type type, string key = "") {if (string.IsNullOrWhiteSpace(key)){return _container.GetAll(type).ToArray();}return _container.GetAll(type, key).ToArray();}#endregion#regionpublic virtual T TryResolve<T>(string key = "", params Common.Runtime.Parameter[] parameters) {if (string.IsNullOrWhiteSpace(key)){return _container.TryGet<T>(ConvertParameters(parameters));}return _container.TryGet<T>(key, ConvertParameters(parameters));}public virtual object TryResolve(Type type, string key = "", params Common.Runtime.Parameter[] parameters) {if (string.IsNullOrWhiteSpace(key)){return _container.TryGet(type, ConvertParameters(parameters));}return _container.TryGet(type, key, ConvertParameters(parameters));}#endregion#region ResolveUnRegisteredpublic T ResolveUnregistered<T>() where T : class{return ResolveUnregistered(typeof (T)) as T;}public object ResolveUnregistered(Type type){var constructors = type.GetConstructors();foreach (var constructor in constructors){var parameters = constructor.GetParameters();var parameterInstances = new List<object>();foreach (var parameter in parameters){var service = Resolve(parameter.ParameterType);if(service==null)parameterInstances.Add(service);}return Activator.CreateInstance(type, parameterInstances.ToArray());}throw new Exception("构造方法没有发现需要依赖的字段");}#endregionpublic void Dispose() {if (this._container != null && !this._container.IsDisposed){this._container.Dispose();}this._container = null;}}

这个类不仅实现了接口还继承Ninject官方类，是为了减少其它程序在做注入的时候减少对Ninject的依赖，有了这个类以后，未来的扩展程序集在注册组件时就不用引用Ninject，对它形成依赖。
