Autofac使用代码方式进行组件注册【不需要依赖】

public class AutofacFactory2
    {
        IBank bank;
        public AutofacFactory2()
        {
            Type objTypeService  = Type.GetType("Cropay.Bank.IBank");
            Type objTypeA = Type.GetType("Cropay.Bank.Bank50");
            Type objTypeB = Type.GetType("Cropay.Bank.Bank51");

            var builder = new ContainerBuilder();
            builder.RegisterType(objTypeA).Named("Cropay.Bank.Bank50", objTypeService);
            builder.RegisterType(objTypeB).Named("Cropay.Bank.Bank51", objTypeService);

            IContainer container = builder.Build();
            bank = container.ResolveNamed<IBank>("Cropay.Bank.Bank51");

        }
