在ninject中将参数传递给接口类

Question

我有一堂课要举行这样的会议

public class SessionService : ISession
{
    public HttpContext Context { get; set; }

    public SessionService(HttpContext context)
    {
        this.Context = context;
    }
}

我希望能够在我的 MVC3 应用程序的不同位置注入会话对象。 我有这个界面

interface ISession
{
    HttpContext Context { get; set; }
}

我正在使用ninject将会话类绑定到这样的接口

private void RegisterDependencyResolver()
{
    var kernel = new StandardKernel();
    kernel.Bind<ISession>().To<SessionService>();
    DependencyResolver.SetResolver(new NinjectDependencyResolver(kernel));
}

我的问题是如何将 Httpcontext 参数传递给 SessionService 构造函数。

任何最受赞赏的指针。

谢谢

无论您在哪里设置依赖项：

kernel.Bind<HttpContext>().ToMethod(c => HttpContext.Current);

我有一个使用 RegisterServices 方法执行此操作的引导程序类：

public static class NinjectMVC3
{
    private static readonly Bootstrapper bootstrapper = new Bootstrapper();

    /// <summary>
    /// Starts the application
    /// </summary>
    public static void Start()
    {
        DynamicModuleUtility.RegisterModule(typeof(OnePerRequestModule));
        DynamicModuleUtility.RegisterModule(typeof(HttpApplicationInitializationModule));
        bootstrapper.Initialize(CreateKernel);
    }

    /// <summary>
    /// Stops the application.
    /// </summary>
    public static void Stop()
    {
        bootstrapper.ShutDown();
    }

    /// <summary>
    /// Creates the kernel that will manage your application.
    /// </summary>
    /// <returns>The created kernel.</returns>
    private static IKernel CreateKernel()
    {
        var kernel = new StandardKernel();
        RegisterServices(kernel);
        return kernel;
    }

    /// <summary>
    /// Load your modules or register your services here!
    /// </summary>
    /// <param name="kernel">The kernel.</param>
    private static void RegisterServices(IKernel kernel)
    {            
        kernel.Bind<HttpContext>().ToMethod(c => HttpContext.Current);
    }
}
