文章说明，文本内容基于配置文件进行依赖注入
unity介绍：Unity是由微软的Patterns
& Practices团队开发的一个轻量级、可扩展的依赖注入（Dependency Injection,
DI）容器，支持拦截、构造函数注入、属性注入和方法调用注入。
属性注入：
<configSections>
<section
name="unity"
type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection,
Microsoft.Practices.Unity.Configuration" />
</configSections>
<unity>
<alias alias="Class"
type="Unity.Class,Unity" />
<container>
<register type="Student" name="MyStudent">
<constructor>
<param name="name" type="System.String" value="BBBB"/>
<param name="Studentage" type="System.Int32"
value="12"/>
</constructor>
</register>
<register
type="Class" name="MyClass">
<!--属性注入
-->
<property name="ClassName"
propertyType="System.String" value="电脑班" />
<!--对象属性注入-->
<property name="NewStudent" >
<dependency
name="MyStudent" type="Unity.Student,Unity" />
</property>
</register>
</container>
<unity>
构造函数注入：
<configSections>
<section
name="unity"
type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection,
Microsoft.Practices.Unity.Configuration" />
</configSections>
<unity>
<alias
alias="Student" type="Unity.Student,Unity" />
<container>
<!--构造函数注入 -->
<register
type="Student" name="MyStudent">
<constructor>
<param
name="name" type="System.String" value="BBBB"/>
<param
name="Studentage" type="System.Int32" value="12"/>
</constructor>
</register>
</container>
<unity>
方法注入：
<configSections>
<section
name="unity"
type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection,
Microsoft.Practices.Unity.Configuration" />
</configSections>
<unity>
<alias alias="Class" type="Unity.Class,Unity"
/>
<container>
<register
type="Class" name="MyClass">
<method
name="CreateTeacher">
<param
name="person" type="IPerson">
<dependency
type="Teacher"/>
</param>
</method>
</register>
</container>
<unity>
