程序集扫描 

  扫描类型

var dataAccess = Assembly.GetExecutingAssembly();

builder.RegisterAssemblyTypes(dataAccess)
       .Where(t => t.Name.EndsWith("Repository"))
       .AsImplementedInterfaces();

 过滤类型

　

   var dataAccess = Assembly.GetExecutingAssembly();

            var builder = new ContainerBuilder();
            builder.RegisterAssemblyTypes(dataAccess)
                   .Where(t => t.Name.EndsWith("IG"))
                   .PropertiesAutowired()            //设置属性自动注入
                   .PublicOnly()                        //过滤修饰符，如 internal 类型的类或属性不被注入
                   .Except<AssemblyBIG>()        //过滤类型
                   .AsImplementedInterfaces(); //注入为所依赖的接口类型

            var container = builder.Build();

            IAssemblyAIG aIG = container.Resolve<IAssemblyAIG>();
            Console.WriteLine(aIG.Get());

扫描模块与模块注入

 

var builder = new ContainerBuilder();

var assembly = typeof(AssemblyAIG).Assembly;
//通过程序集扫描模块
builder.RegisterAssemblyModules(assembly);
//模块注入
builder.RegisterModule(new AssemblyTransportModule()
{
	ObeySpeedLimit = true
});

var container = builder.Build();

IAssemblyAIG aIG = container.Resolve<IAssemblyAIG>();
Console.WriteLine(aIG.Get());

IDriver driver = container.Resolve<IDriver>();
driver.Do();  

public class AssemblyTransportModule : Module
{
	public bool ObeySpeedLimit { get; set; }

	protected override void Load(ContainerBuilder builder)
	{
		builder.RegisterType<AssemblyBIG>().As<IAssemblyBIG>();
		builder.Register(c => new AssemblyAIG { BIG = c.Resolve<IAssemblyBIG>() })
				 .As<IAssemblyAIG>();

		if (ObeySpeedLimit)
			builder.Register(c => new AssemblyBIG()).As<IDriver>();
		else
			builder.Register(c => new AssemblyAIG()).As<IDriver>();
	}
}

#生命周期释放

 

var builder = new ContainerBuilder();
builder.RegisterType<SomeComponent>()
       .OnRelease(instance => instance.CleanUp()); //在释放时对示例调用指定释放方法
builder.RegisterType<SomeComponent>().ExternallyOwned(); //禁止自动释放，即生命周期由对象自己管理或者由调用主动释放

 #容器创建回调

var builder = new ContainerBuilder();
builder
   .RegisterBuildCallback(c => c.Resolve<DbContext>());

// The callback will run after the container is built
// but before it's returned.
var container = builder.Build();
