c# - 防止简单注入(inject)器与 Umbraco Controller 发生冲突

Question

尽管在我的 Umbraco 解决方案中只注册了我自己的 mvc Controller ，简单的注入(inject)器似乎也影响了 Umbraco 的后台 Controller 。如果我运行下面的代码片段，Umbraco 后台 Controller 会出现异常，类似于 this thread 中的问题。 .

我是否还需要添加自定义 Controller 激活器之类的东西？

protected void Application_Start(object sender, EventArgs e) {

    var container = new Container();
    container.Options.DefaultScopedLifestyle = new WebRequestLifestyle();

    var registeredControllerTypes = 
    SimpleInjectorMvcExtensions.GetControllerTypesToRegister(
        container, Assembly.GetExecutingAssembly())
    .Where(type => type.IsSubClassOf(typeof(MyController)));

    foreach (var controllerType in registeredControllerTypes)
    {
        container.Register(controllerType, controllerType, Lifestyle.Transient);
    }

    container.Verify();

    DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(container));
}

解决了 @Steven 评论的更新版本:

public class UmbracoConstructorBehavior : IConstructorResolutionBehavior
{
    public IConstructorResolutionBehavior DefaultBehavior { get; set; }
    public ConstructorInfo GetConstructor(Type implementationType)
    {
        return implementationType.Namespace != null 
          && implementationType.Namespace.Contains("Umbraco")
            ? GetUmbracoConstructor(implementationType)
            : DefaultBehavior.GetConstructor(implementationType);
    }

    private ConstructorInfo GetUmbracoConstructor(Type i) => 
       i.GetConstructors().OrderBy(c => c.GetParameters().Length).FirstOrDefault() 
       ?? DefaultBehavior.GetConstructor(i);
}
