C#学习教程：与ninject的循环依赖分享

我试图弄清楚如何用ninject绑定这样的东西的正确方法。

interface IMainService { void DoStuff(); } interface IOtherService { void DoSomeMagic(); } abstract class BaseClass { //many stuff here } class MainClass : BaseClass, IMainService { public MainClass(IOtherService s) { } public void DoStuff() { throw new NotImplementedException(); } //do many other things } class OtherClass : IOtherService { public OtherClass(IMainService s) { } public void DoSomeMagic() { throw new NotImplementedException(); } } class BaseModule : NinjectModule { public override void Load() { Bind().To(); Bind().To(); Bind().To(); } } static class Program { static void Main() { var kernel = new StandardKernel(new BaseModule()); var main = kernel.Get(); } } 

它给了我例外：

 Error activating IOtherService using binding from IOtherService to OtherClass A cyclical dependency was detected between the constructors of two services. Activation path: 4) Injection of dependency IOtherService into parameter s of constructor of type MainClass 3) Injection of dependency IMainService into parameter s of constructor of type OtherClass 2) Injection of dependency IOtherService into parameter s of constructor of type MainClass 1) Request for MainClass Suggestions: 1) Ensure that you have not declared a dependency for IOtherService on any implementations of the service. 2) Consider combining the services into a single one to remove the cycle. 3) Use property injection instead of constructor injection, and implement IInitializable if you need initialization logic to be run after property values have been injected. 

我不知道怎么写BaseModule。 我只需要一个MainClass实例和一个OtherClass实例（如单例）。

我尝试过这样的事情：

 Bind().To().InSingletonScope(); Bind().To().InRequestScope(); Bind().To().InSingletonScope(); 

但是同样的错误。

如何为MainClass和IMainService接口只使用一个实例编写绑定？

谢谢你的回答。

 public interface IMainService { void DoStuff(); IOtherService OtherService { set; } } public class MainClass { public IOtherService OtherService { get; set; } public void DoStuff() { ... } } public class OtherService { public OtherService(IMainService main) { main.OtherService = this; } } 

 public OtherService(Lazy main) { this.main = main; } public MainClass(Lazy s) { this.s = s; }
