Question

How do I do constructor injection when I’m manually initializing the class?

public class ApiKeyHandler : DelegatingHandler
{
    private IApiService apiService;

    public ApiKeyHandler(IApiService apiService)
    {
        this.apiService = apiService;
    }
}

Initializing:

var apiKey = new ApiKeyHandler(/*inject here */);

How do I accomplish this? My bindings and everything is already setup.

You want to do something like this:

var apiKey = new ApiKeyHandler(kernel.Get<IApiService>());

However, why not inject the ApiKeyHandler itself?

var apiKey = kernel.Get<ApiKeyHandler>();

Here is an article about Ninject:

You basically want to set this up at the beginning of your code and have it available globally:

public IKernel kernel  = new StandardKernel();

…

kernel.Bind<IApiService>()
      .To<SomeConcreteApiService>();
