南希DependencyResolver

Question

我使用南希框架和autofac，我不喜欢这样的引导程序：

var services = Assembly.Load("ProjectDomain"); 
builder.RegisterAssemblyTypes(services) 
    .AsClosedTypesOf(typeof(ICommandHandler<>)) 
    .InstancePerRequest(); 
builder.RegisterAssemblyTypes(services) 
    .AsClosedTypesOf(typeof(IValidationHandler<>)) 
    .InstancePerRequest(); 

，但它不工作.....

ICommandHandler<TCommand> handler = 
    DependencyResolver.Current.GetService<ICommandHandler<TCommand>>(); 

处理器为null！如何解决它？帮助我，谢谢...

Answer 1

我相信你注册的类型AsSelf（这是默认的autofac行为）。你可以试试吗？

builder.RegisterAssemblyTypes(services) 
    .AsClosedTypesOf(typeof(ICommandHandler<>)) 
    .AsImplementedInterface() 
    .InstancePerRequest();
