Constructor Inject with Ninject 2
I've used Ninject with MVC3 for automagic inject of constructor arguments. It worked great.
How do you do something similar with non-MVC code.
For example:
public class Ninja
{
private readonly IWeapon _weapon;
public Ninja(IWeapon weapon)
{
_weapon = weapon;
}
public void Strike()
{
_weapon.Strike();
}
}
public class MyProgram
{
public void DoStuff()
{
var Ninja = new Ninja(); // I'm wanting Ninject to call the parameterized Ninja constructor
ninja.St开发者_Go百科rike();
}
}
How would I alter the code to get it to work?
public interface IWeapon
{
void Strike();
}
public class Sword : IWeapon
{
public void Strike()
{
Console.WriteLine("black ninja strike");
}
}
public class Ninja
{
private readonly IWeapon _weapon;
public Ninja(IWeapon weapon)
{
_weapon = weapon;
}
public void Strike()
{
_weapon.Strike();
}
}
public class WarriorModule : NinjectModule
{
public override void Load()
{
Bind<IWeapon>().To<Sword>();
}
}
class Program
{
static void Main()
{
var kernel = new StandardKernel(new WarriorModule());
var ninja = kernel.Get<Ninja>();
ninja.Strike();
}
}
Wouldn't it just be:
var ninja = Kernel.Get<Ninja>();
You obviously have to resolve the dependency though Ninject.
You need to have an instance of StandardKernel
let's call it kernel
and then use kernel.Get<Ninja>()
. This works since Ninja is non abstract, so it is considered bound to itself. Obviously some concrete types needs to be bound to IWeapon to allow NInject to create Ninja.
