参考与此http://caliburn.codeplex.com/wikipage?title=Auto-Registering%20Components&referringTitle=Documentation 此为基础,看了没用,不看不行…了解下注册流程.
1.内置服务则用手动注册. 2.挂元数据标签,如下 [PerRequest(typeof(IHomePresenter))] public class HomePresenter : Presenter,IHomePresenter { }
3.外部dll加载 重写CaliburnApplication的SelectAssemblies方法 protected override System.Reflection.Assembly[] SelectAssemblies() { return new[] { Assembly.GetEntryAssembly(),typeof(Caliburn.WPF.ApplicationFramework.Bind).Assembly}; } private void InspectAssembly(Assembly assembly,ICollection<ComponentInfo> componentList,ICollection<Type> configs) { var types = assembly.GetExportedTypes(); foreach (var type in types) { foreach (var attribute in type.GetCustomAttributes(true).OfType<RegisterAttribute>()) componentList.Add(attribute.GetComponentInfo(type)); } foreach (var type in types) { if(_configType.IsAssignableFrom(type) && !type.IsAbstract) configs.Add(type); } }
内置服务+自定义服务注册好以后,接下来的任务就是注册实例.即组件的生命周期状况.内置都为Singleton /// <summary> /// The lifetime of a Caliburn component. /// </summary> public enum ComponentLifetime { /// <summary> /// One instance per application. /// </summary> Singleton,/// <summary> /// A new instance is created on each request. /// </summary> PerRequest,/// <summary> /// A new instance is created per custom lifetime rules. /// </summary> Custom }
新版本可能会更新,所以不去研究它了 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
