Question

我正在尝试在FilterAttribute类中使用属性Setter注入方法

以下是我的AttributeFilter

 public class HasIfNoneMatchAttribute : ActionFilterAttribute
 {
    [Inject]
    public ICorporationRepository _corporationRepository { set; private get;    }

    public override void OnActionExecuting(HttpActionContext actionContext)
    {
        var request = actionContext.Request;

        ICollection<EntityTagHeaderValue> etagsFromClient = request.Headers.IfNoneMatch;

        if (etagsFromClient.Count > 0)
        {
            EntityTagHeaderValue etag = new EntityTagHeaderValue(this._corporationRepository.GetETagForCorporationRequirement("param1", "param2", "param3"));
            if (etagsFromClient.Contains(etag))
            {
                actionContext.Response = new HttpResponseMessage(HttpStatusCode.NotModified);
               // SetCacheControl(context.Response);
            }
        }

        base.OnActionExecuting(actionContext);
    }}
}

我已在项目中使用构造函数注入。哪个工作正常。以下是我的NinjectWebCommon.cs文件的一部分

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

    public static void Start() 
    {
          DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule));
        DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule));
        bootstrapper.Initialize(CreateKernel);
    }

    public static void Stop()
    {
        bootstrapper.ShutDown();
    }

    private static IKernel CreateKernel()
    {
        var kernel = new StandardKernel();
        kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
        kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();

        RegisterServices(kernel);
        return kernel;
    }

    private static void RegisterServices(IKernel kernel)
    {

        kernel.Bind<ICorporationRepository>().To<CorporationRepository>();
}

属性没有被注入，我得到错误 - System.NullReferenceException：未将对象引用设置为对象的实例。

我错过了什么？

属性设置器注入[注入]不起作用
