关于c＃：可以在Windsor容器中注册类型的现有实例吗？

Can you register an existing instance of a type in the Windsor Container?

在Windsor IOC容器中，可以注册一个我已有实例的类型，而不用让该容器创建它吗？

容器的内核属性上有一个AddComponentInstance方法。

[Test]
public void AddComponentInstance()
{
CustomerImpl customer = new CustomerImpl();

kernel.AddComponentInstance("key", typeof(ICustomer), customer);
Assert.IsTrue(kernel.HasComponent("key"));

CustomerImpl customer2 = kernel["key"] as CustomerImpl;
Assert.AreSame(customer, customer2);

customer2 = kernel[typeof(ICustomer)] as CustomerImpl;
Assert.AreSame(customer, customer2);
}

[Test]
public void AddComponentInstance_ByService()
{
CustomerImpl customer = new CustomerImpl();

kernel.AddComponentInstance <ICustomer>(customer);
Assert.AreSame(kernel[typeof(ICustomer)],customer);
}

[Test]
public void AddComponentInstance2()
{
CustomerImpl customer = new CustomerImpl();

kernel.AddComponentInstance("key", customer);
Assert.IsTrue(kernel.HasComponent("key"));

CustomerImpl customer2 = kernel["key"] as CustomerImpl;
Assert.AreSame(customer, customer2);

customer2 = kernel[typeof(CustomerImpl)] as CustomerImpl;
Assert.AreSame(customer, customer2);
}
