Orchard CMS中的Work 类是什么？

简单明了， Orchard\Environment\WorkContextModule.cs定义的Orchard.Environment.Work类的用例是什么？

它可以在几个地方找到

 private readonly Work _containerService; public Shapes(Work containerService) { _containerService = containerService; ... 

是否延迟解决IContainerService ？

Answer 1

Work类用于延迟加载依赖项注入。 实例化类时不依赖于依赖关系，但仅在调用Value属性时才解决：

 private readonly IMyService _myService; private readonly IMyOtherService _myOtherService; public MyClass(Work myService, IMyOtherService myOtherService) { // Just assign the Work class to the backing property // The dependency won't be resolved until '_myService.Value' is called _myService = myService; // The IMyOtherService is resolved and assigned to the _myOtherService property _myOtherService = myOtherService; } 

现在只有在调用_myService.Value时，依赖性解析器才能解析IMyService，这使您可以处理延迟加载依赖项注入。
