ref

是用来表示是关联到哪个

object

ContextRegistry.GetContext()方法:

该方法是获取配置文件中的如下内容，且把它们装入容器中,在配置这段xml信息时，spring和context节点的名称不是任意的，必须是"spring"和"context"，Spring.NET本身将"spring/context"作为字符串常量定义在了AbstractApplicationContext类中以表示上下文的节点名称

<context>
<resource uri="config://spring/objects" />

<objects xmlns="http://www.springframework.net">
<object id="person" type="SpringNetIocExample.Person,SpringNetIocExample">
<!--属性值类型注入-->
<property name="Name" value="jackyong"/>
<property name="Age" value="25"/>

<!--内联对象注入-->
<property name="Friend">
<object type="SpringNetIocExample.Person, SpringNetIocExample">
<property name="Name" value="jackpeng"/>
<property name="Age" value="23"/>
<property name="Friend" ref="person"/>

</object>
</objects>
</spring>

Person person = ctx.GetObject("person") as Person;

这句代码就是

从容器中寻找id 为person的object(包含了所有的子节点),将其实例化为person，此时person实例的所有属性已经被赋值了
