You can accomplish this using WithConstructorArgument
and using a callback:
kernel.Bind<AnalyticsController>()
.ToSelf()
.WithConstructorArgument("isLiveEnvironment", ctx => MultiTenancyDetection.GetInstance().IsLive() );
Frage
I have a constructor such as:
public AnalyticsController(ClassA classA, ClassB classB, bool isLiveEnvironment)
{
...
}
isLiveEnvironment
is determined using a call to an existing static class such as:
MultiTenancyDetection.GetInstance().IsLive();
I would like to be able to make this call outside of the controller and inject the result into isLiveEnvironment. Is this possible? I can not see how this can be done.

You can even achieve this more generally (but i would not really recommend binding such a generic type for such a specific use case):
IBindingRoot.Bind<bool>().ToMethod(x => MultiTenancyDetection.GetInstance().IsLive())
.When(x => x.Target.Name == "isLiveEnvironment");
Alternatively, if you need the same configuration value in several / a lot of classes, create an interface for it:
public interface IEnvironment
{
bool IsLive { get; }
}
internal class Environment : IEnvironment
{
public bool IsLive
{
get
{
return MultiTenancyDetection.GetInstance().IsLive();
}
}
}
IBindingRoot.Bind<IEnvironment>().To<Environment>();
