Ninject: Singleton binding syntax?
- by Rosarch
I'm using Ninject 2.0 for the .Net 3.5 framework. I'm having difficulty with singleton binding.
I have a class UserInputReader which implements IInputReader. I only want one instance of this class to ever be created.
public class MasterEngineModule : NinjectModule
{
public override void Load()
{
// using this line and not the other two makes it work
//Bind<IInputReader>().ToMethod(context => new UserInputReader(Constants.DEFAULT_KEY_MAPPING));
Bind<IInputReader>().To<UserInputReader>();
Bind<UserInputReader>().ToSelf().InSingletonScope();
}
}
static void Main(string[] args)
{
IKernel ninject = new StandardKernel(new MasterEngineModule());
MasterEngine game = ninject.Get<MasterEngine>();
game.Run();
}
public sealed class UserInputReader : IInputReader
{
public static readonly IInputReader Instance = new UserInputReader(Constants.DEFAULT_KEY_MAPPING);
// ...
public UserInputReader(IDictionary<ActionInputType, Keys> keyMapping)
{
this.keyMapping = keyMapping;
}
}
If I make that constructor private, it breaks. What am I doing wrong here?
