Question

我正在尝试在我的新项目上设置Ninject，我想使用对流扫描装配，以便

IFoo

将自动解析为

IBar

所有样本和文档都描述了使用这种方法

kernel.Scan(...)

虽然Ninject 3内核似乎使用了.Load。如果我使用Load进行扫描，那么如何使用约定配置扫描？

修改

我能够使用https://github.com/ninject/ninject.extensions.conventions/wiki/What-is-configuration-by-convention

让它正常工作

但是，现在我无法加载我的模块。我正在使用下面的代码并得到以下错误。

    IKernel kernel = new StandardKernel();
    kernel.Bind(x => x
        .FromAssembliesMatching("Crt.*.dll")
        .SelectAllTypes()
        .BindAllInterfaces()
        );
    kernel.Load("*.dll");
    return kernel;

错误：

Ninject.ActivationException was unhandled
  Message=Error activating ITrainingEngine
More than one matching bindings are available.
Activation path:
  1) Request for ITrainingEngine

Suggestions:
  1) Ensure that you have defined a binding for ITrainingEngine only once.

Answer 1

使用SelectAllClasses而不是SelectAllTypes

Ninject 3.0中基于约定的绑定
