c# - 将非实例化的类和接口(interface)传递给泛型方法

Question

我继承了数百个这样的声明:

mockKernel.Setup(x => x.Bind<IAddressService>().To<AddressService>())
          .Returns(new BindingConfigurationBuilder<AddressService>(bindingConfiguration, "ServiceName", mockKernel.Object));

...作为数百个类似以下语句的测试的一部分:

_kernel.Bind<IAddressService>().To<AddressService>().InRequestScope();

我想写这样的东西:

private void SetupBindAtoB<TInterface, TImplementation>(TInterface a, TImplementation b)
    where TImplementation : TInterface
{
  mockKernel.Setup(x => x.Bind<TInterface>().To<TImplementation>())
            .Returns(new BindingConfigurationBuilder<TImplementation>(bindingConfiguration, "ServiceName", mockKernel.Object));
}

...然后这样调用它:

SetupBindAtoB(IAddressService, AddressService);

但我不能。我必须将一个真实的对象传递给 SetupBindAtoB，如下所示:

SetupBindAtoB((IAddressService) null, (AddressService) null);

是否可以避免创建传递给 SetupBindAtoB 的真实对象？

Answer 1

你试过这个吗？

private void SetupBindAtoB<TInterface, TImplementation>()
    where TImplementation : TInterface
{
  mockKernel.Setup(x => x.Bind<TInterface>().To<TImplementation>())
            .Returns(new BindingConfigurationBuilder<TImplementation>(bindingConfiguration, "ServiceName", mockKernel.Object));
}

使用

SetupBindAtoB<IAddressService,AddressService>();
