"Error loading Ninject component ICache"第二次致电我的服务

Question

我第一次打电话给我的服务一切正常。之后，我收到此错误："错误加载ninject组件icache r nno此组件已在内核组件容器中注册。

我称之为的控制器将Ikernel作为其构造函数中的参数，我的猜测是这是问题所在。

我应该如何将内核对象传递到我的服务中？

我的控制器构造函数：

public MyController(IKernel diContainer)
    {
        _diContainer = diContainer;
    }

我的global.asax文件的一部分：

var kernel = NinjectWebApi.Kernel;
kernel.Bind<IMyController().To<MyController();
//Set the dependency resolver to use ninject
GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel);

我正在使用ninject 3.2。

对于我没有传递内核的其他服务，此方法正常。

public class NinjectDependencyScope : IDependencyScope
{
    private IResolutionRoot _resolver;
    public NinjectDependencyScope(IResolutionRoot resolver)
    {
        _resolver = resolver;
    }
    public object GetService(Type serviceType)
    {
        if (_resolver == null)
        {
            throw new ObjectDisposedException("this", "This scope has been disposed.");
        }
        return _resolver.TryGet(serviceType);
    }
    public IEnumerable<object> GetServices(Type serviceType)
    {
        if (_resolver == null)
        {
            throw new ObjectDisposedException("this", "This scope has been disposed.");
        }
        return _resolver.GetAll(serviceType);
    }
    public void Dispose()
    {
        var disposable = _resolver as IDisposable;
        disposable?.Dispose();
        _resolver = null;
    }
}
public class NinjectDependencyResolver : NinjectDependencyScope, IDependencyResolver
{
    private readonly IKernel _kernel;
    public NinjectDependencyResolver(IKernel kernel) : base(kernel)
    {
        _kernel = kernel;
    }
    public IDependencyScope BeginScope()
    {
        return new NinjectDependencyScope(_kernel.BeginBlock());
    }
}

看来您将容器放置在ninjectdependendependenvyvyresolver处置方法中。
