我试图用“结构映射”来获取一个非常简单的装饰图案版本,但我无法让它发挥作用。这是我的代码(注意断点):

public interface ITestClass { void DoSomething(); }

public class TestClass : ITestClass
{
    public void DoSomething()
    {
        Console.WriteLine("Doing something"); //Breakpoint
    }
}

public class LoggingTestClass : ITestClass
{
    private ITestClass originalClass;

    public LoggingTestClass(ITestClass original)
    {
        originalClass = original; //Breakpoint
    }
    public void DoSomething()
    {
        Console.WriteLine("Log start");
        originalClass.DoSomething();
        Console.WriteLine("Log finish");
    }
}

在我的注册簿中:

For<ITestClass>().Use<TestClass>().
EnrichWith(original => new LoggingTestClass(original));

最后,一个考验:

[TestMethod]
    public void DoSomeTesting()
    {
        using (IContainer container = new Container(new ApiRegistry()))
        {
            ITestClass testClass = container.GetInstance<TestClass>(); //Breakpoint
            testClass.DoSomething();
        }
    }

当我调试测试时,我先在测试中打中断点,然后在 DoSomething () 方法中打中断点。 LogingTestClass 的构建者从未被执行。

我不知道我如何能进一步简化它, 似乎EnrichOn根本不被叫...

我似乎非常愚蠢! 我当时使用的是 GetInstance & lt; testClass> 而不是 GetInstance & lt; ItestClass> 。这个小东西让我忙了几个小时! 继续谈论你的商人。
