尽管在我的Umbraco解决方案中只重新使用了我自己的mvc控制器,但简单的注入器似乎也影响了Umbraco的后台控制器。如果我运行下面的代码段,Umbraco后台控制器会遇到异常,类似于this thread中的问题。
我是否还需要添加类似自定义控制器激活器的东西?
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);
}
