**接：IOC-Spring.net简单使用一**

**1.属性注入**

**2.构造函数注入**

<object name="PropertyDal2" type="SpringNetTest.AdoNetUserInfoDal,SpringNetTest">
        <constructor-arg index="0" value="小猪"></constructor-arg>
        <constructor-arg index="1" ref="UserInfo"></constructor-arg>
      </object>
    
      <object name="UserInfo" type="SpringNetTest.UserInfo,SpringNetTest">
        <property name="Name" value="猪猪"></property>
        <property name="Age" value="2"></property>
      </object>

**3.容器的配置**

**4.完整代码**

app.config

<?xml version="1.0" encoding="utf-8"?>
    <configuration>
    
      
      <configSections>
        
        <sectionGroup name="spring">
          <section name="context" type="Spring.Context.Support.ContextHandler,Spring.Core"></section>
          <section name="objects" type="Spring.Context.Support.DefaultSectionHandler,Spring.Core" />
        </sectionGroup>
      </configSections>
    
      
      <spring>
        <context>
          
          
          
          <resource uri="assembly://SpringNetTest/SpringNetTest/objects.xml"></resource>
        </context>
    
      </spring>
    
      <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
      </startup>
    
    </configuration>

IUserInfo和实现类

public interface IUserInfoDal
        {
            UserInfo UserInfo { get; set; }
            string Name { get; set; }
            void Show();
        }
        public class AdoNetUserInfoDal : IUserInfoDal
        {
            public AdoNetUserInfoDal(string name,UserInfo userinfo)
            {
                this.UserInfo = userinfo;
                this.Name = name;
            }
    
            public UserInfo UserInfo { get; set; }
            public string Name { get; set; }
            public void Show()
            {
                Console.WriteLine("我是ADO.Net Dal,属性注入Name=" + Name);
                Console.WriteLine("我是ADO.Net Dal,UserInfo Name=" + UserInfo.Name + "\\\\Age=" + UserInfo.Age);
            }
        }
        public class EFUserInfoDal : IUserInfoDal
        {
            public EFUserInfoDal()
            {
    
            }
            public UserInfo UserInfo { get; set; }
            public string Name { get; set; }
            public void Show()
            {
                Console.WriteLine("我是EF Dal,属性注入Name="+Name);
                Console.WriteLine("我是EF Dal,UserInfo Name=" + UserInfo.Name + "\\\\Age=" + UserInfo.Age);
            }
        }

UserInfo

public class UserInfo
        {
            public string Name { get; set; }
            public int Age { get; set; }
        }

objects.xml

<?xml version="1.0" encoding="utf-8" ?>
    <objects xmlns="http://www.springframework.net">
      
      <description>An  example that demonstrates simple IoC features.</description>
      
      
    
      <object name="PropertyDal" type="SpringNetTest.EFUserInfoDal,SpringNetTest">
        <property name="Name" value="朵朵"></property>
        
        <property name="UserInfo" ref="UserInfo"></property>
      </object>
    
      
      <object name="PropertyDal2" type="SpringNetTest.AdoNetUserInfoDal,SpringNetTest">
        <constructor-arg index="0" value="小猪"></constructor-arg>
        <constructor-arg index="1" ref="UserInfo"></constructor-arg>
      </object>
    
      
      <object name="UserInfo" type="SpringNetTest.UserInfo,SpringNetTest">
        <property name="Name" value="猪猪"></property>
        <property name="Age" value="2"></property>
      </object>
    
    </objects>

Program

namespace SpringNetTest
    {
        class Program { 
            static void Main(string[] args)
            {
                //控制权没有反转
                //IUserInfoDal infoDal = new EFUserInfoDal();
    
                //Spring.Net 创建实例的方式转为容器帮我们创建
                //创建spring容器上下文
                IApplicationContext ct = ContextRegistry.GetContext();
    
                IUserInfoDal efdal = ct.GetObject("PropertyDal2") as IUserInfoDal;
    
                efdal.Show();
    
                IUserInfoDal adodal = ct.GetObject("PropertyDal") as IUserInfoDal;
    
                adodal.Show();
    
                Console.ReadKey();
            }
        }
    }

结果：
