IOC依賴注入集合屬性

person類：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace t1_IoCTest
{
    //說明：如果需要使用IoC，前提是這個類及使用這個類的地方，不在同一個程序集中

    public interface IPerson
    {
        void Say();
    }

    public partial class Person:IPerson
    {
        //constructor
        public Person()
        {
            
        }

        public Person(string name)
        {
            Name = name;
        }

        public Person(int age)
        {
            Age = age;
        }

        public Person(string name, int age)
        {
            Name = name;
            Age = age;
        }

        public string Name { get; set; }
        public int Age { get; set; }
        public Car MyCar { get; set; }

        public List<String> MyCarList { get; set; }    //String類型，若是Car類型，則配置文件中添加對另一注入屬性節點的引用

        public void Say()
        {
            //Console.WriteLine("Hello {0},MyCar Brand:{1}",Name,MyCar.Brand);
            foreach(var item in MyCarList){
                Console.WriteLine(item);
            }
        }
    }

    public class Car
    {
        public string Brand { get; set; }

	//重寫ToString方法

	public override ToString(){

		return Brand;

	}
    }
}

program。cs：main方法

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Spring.Context;
using Spring.Context.Support;
using Spring.Core;

namespace t1_IoCTest
{
    class Program
    {
        static void Main(string[] args)
        {
            //1、創建容器對象
            IApplicationContext ctx = ContextRegistry.GetContext();

            //2、聲明接口類型的變量
            IPerson p;

            //3、通過容器創建對象
            //p = ((IObjectFactory) ctx).GetObject("Zxh") as IPerson;
            p = ctx.GetObject<IPerson>("Zxh");

            //4、完成對象成員的調用
            p.Say();

            Console.ReadKey();
        }
    }
}

app.config配置文件:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
      <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
    </sectionGroup>
  </configSections>
  
  <spring>
    <context>
      <resource uri="config://spring/objects"/>
    </context>
    <objects xmlns="http://www.springframework.net">
      <description>An  example that demonstrates simple IoC features.</description>
      <!--type中逗號左邊是類的完整名稱，右邊是類的程序集的名稱-->
      <object name="Zxh" type="t1_IoCTest.Person,t1_IoCTest">
        
        
        <property name="MyCarList">
          <list>
            <value>jk</value>
            <value>nll</value>
            <value>yzk</value>

	    <!-- 若前面MyCarList爲List<Car>類型，則引用其他注入屬性 -->

	    <!-- <ref object="MyCar1"/> -->

          </list>
        </property>
      </object>
      <object name="MyCar1" type="t1_IoCTest.Car,t1_IoCTest">
        <property name="Brand" value="BMW"/>
      </object>
       <object name="MyCar2" type="t1_IoCTest.Car,t1_IoCTest">
        <property name="Brand" value="Audi"/>
      </object>
    </objects>
  </spring>
  
  
</configuration>

集合屬性注入結果：

MyCarList改爲List<Car>類型後，輸出爲：

重寫Car類的ToString方法後 ：
