Hi all.

I am trying to reflect all classes of a specific interface and run a method. This works until i try to use services into the class constructor, like the IScopeProvider.

So i need to be able to get my Activator.CreateInstance(type) to pick up all paramaters in the constructor with Dependency Injection.

Does anyone know what to do?

This is what i have:

My interface to find

public interface IFindMe
{
    string Name { get; }
    void PerformRun();
}

Class to reflect

public class TestJob : IFindMe
{
    private readonly IScopeProvider _scopeProvider;

    public TestJob(IScopeProvider scopeProvider)
    {
        _scopeProvider = scopeProvider;
    }

    public string Name => "Find me ffs";

    public void PerformRunAsync()
    {
        using (var scope = _scopeProvider.CreateScope(autoComplete: true))
        {
            // Just to try something
            var instanceId = scope.InstanceId;
        }
    }
}

IComponent, where all the interfaces are picked up

public class FindMeComponent : IComponent
{
    private readonly ILogger _logger;

    public FindMeComponent(ILogger logger)
    {
        // When it works i wanna log things :)
        _logger = logger;
    }

    public void Initialize()
    {
        var listOfTypes = new List<Type>();

        var assemblies = AppDomain.CurrentDomain.GetAssemblies();
        foreach (var assembly in assemblies)
        {
            try
            {
                var foundTypes = assembly.GetTypes();
                listOfTypes.AddRange(foundTypes);
            }
            catch (ReflectionTypeLoadException e)
            {
                var exceptionTypes = e.Types.Where(t => t != null);
                listOfTypes.AddRange(exceptionTypes);
            }
        }

        var type = typeof(IFindMe);
        var types = listOfTypes.Where(t => type.IsAssignableFrom(t) && !t.IsInterface);
        foreach (var type in types)
        {
            // This works until i use a class that has parameters in the contructor.
            object calcInstance = Activator.CreateInstance(type);
            var name = (string)type.GetProperty("Name").GetValue(calcInstance, null);
            var methodInfo = _type.GetMethod("PerformRun");
            methodInfo.Invoke(_calcInstance, null);
        }
    }

    public void Terminate()
    {

    }
}

IUserComposer, where i register the FindMeComponent

public class Installer : IUserComposer
{
    public void Compose(Composition composition)
    {
        composition.Components().Append<FindMeComponent>();
    }
}
