resolve NLog instance with unity container

c#, dependency-injection, unity-container

Solution

Here is how I've done:

IUnityContainer container = new UnityContainer();
container.RegisterType<ILogger>(
    new InjectionFactory(l => LogManager.GetCurrentClassLogger()));
container.RegisterType<TestInjection>();

var myTestClass = container.Resolve<TestInjection>(
    new ResolverOverride[]
    {
        new ParameterOverride("logger", container.Resolve<ILogger>())
    });
myTestClass.Process();

Problem

I have the following class: ``` public class TestInjection { private ILogger logger; public TestInjection(ILogger logger) { this.logger = logger; } public void Process() { try { int zero = 0; int result = 5 / zero; } catch (DivideByZeroException ex) { logger.Log(LogLevel.Error, "test message", ex); Console.WriteLine("logged message from class"); } } } ``` And in my `Program.cs` I have the code: ``` IUnityContainer container = new UnityContainer(); container.RegisterType<TestInjection>(); var myTestClass = container.Resolve<TestInjection>(new ResolverOverride[] { new ParameterOverride("logger", LogManager.GetCurrentClassLogger()) }); myTestClass.Process(); ``` How to resolve `LogManager.GetCurrentClassLogger()` with the unity container, if the default constructor of the `Logger` class it's not accessible? PS: This is my first experience with DI and Unity.
