微软Unity-问题解决 [英] Microsoft Unity- Issue With Resolve

问题描述

我希望做这样的：

container.Resolve（）;

container.Resolve();

当它这样做，它要一个IDependency注入到底层的实体对象。然而，容器内存储的依赖性要求类型DependencyValue，被提供从一个DependencyFactory一个值的一个目的。所以长话短说，我遇到的问题是，我需要的时候统一创建类的实现IDependency，我将能够接管并插入自定义值不是在容器中的实例。

When it does this, its going to inject a IDependency into the underlying entity object. However, the dependency stored within the container requires an object of type DependencyValue, which is supplied a value from a DependencyFactory. So long story short, the issue I'm having is that I need to, when Unity creates the instance of class implementing IDependency, that I would be able to take over and insert a custom value not in the container.

这是可能的，或者是使用RegisterInstance在容器上，然后手动实例化对象，我最好的选择？我preFER使用配置文件来存储映射，然后添加一些逻辑参数实例。是什么ParameterOverrides是为了做什么？或者，我需要添加一个扩展这一点，还是什么？

Is that possible, or is my best bet to use RegisterInstance on the container and manually instantiate the objects? I prefer using the configuration file to store the mapping, and then add some logic for parameter instantiation. Is that what the ParameterOverrides is meant to do? Or do I need to add an extension for this, or what?

感谢。

推荐答案

你为什么不使用静态工厂扩展？

Why don't you use the static factory extension?

var container = new UnityContainer();
container.AddNewExtension()
         .Configure()
         .RegisterFactory(container =>
                          DependencyFactory.GetValue());
