Castle windsor - Unable to register a proper component with argumants

Question

In a unit test I resolve an interface with sending arguments for its constructor as below:

var args = new { arg1 = "arg1 value", arg2 = "arg2 value" };
var component = container.Resolve<IMyDependency>(args);

and it works fine. But now I want to do it in constructor injection, for example in:

public class Foo
{
     private IMyDependency _dep;
     public Foo(IMyDependency dep) { _dep = dep; }
}

So, As a try I register it with UsingFactoyMethod() like this:

public class BarInstaller : IWindsorInstaller
{
    public void Install(IWindsorContainer container, IConfigurationStore store)
    {
        container.Register(
            Component.For<IMyDependency>().UsingFactoryMethod(
                () =>
                {
                    var args = new { arg1 = "arg1 value", arg2 = "arg2 value" };
                    var result = container.Resolve<IMyDependency>(args);
                    return result;
                }).LifestyleTransient());

        // + some other registerations and installs
    }
}

But I have still error:

Can't create component 'namespace.MyDependency' as it has dependencies to be satisfied.

'namespace.MyDependency' is waiting for the following dependencies:
- Parameter 'arg1' which was not provided. Did you forget to set the dependency?
- Parameter 'arg2' which was not provided. Did you forget to set the dependency?

Answer 1

I think you should try register IMyDependency implementaion with it's constructor args instead of using "UsingFactoyMethod()":

string someArg = "something";
container.Register(
        Component.For<IMyDependency>().ImplementedBy<MyDependencyImp>()
           .DependsOn(Dependency.OnValue("someArg",someArg)).LifestyleTransient());

Assuming MyDependencyImp constructor looks something like this:

public MyDependencyImp(string someArg)
{
    /....
}

Do you register IMyDependency anywhere else? It's tough to say what's wrong until you post the actual code.

This should work:

container.Register(
        Component.For<IMyDependency>().UsingFactoryMethod(
            () =>
            {
                return new MyDependency("arg1 value", "arg2 value");
            }).LifestyleTransient());
