spring.net ioc example

step1:

add the reference "spring.core.dll"

step2:

make a configuration file:

 

<?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-->
  <objects xmlns="http://www.springframework.net/">
    <description>An example demonstrating the event registry.</description>
    <object name="HelloWorld" type="LiveDevTest.HelloWorld" singleton="false">
      <!--<property name="str" value="HelloWorld" />-->
   </object>

    <object name="HelloWorld2" type="LiveDevTest.HelloWorld2" singleton="false">
      <property name="Msg" value="HelloWorld,I'm a parameter from config" />
    </object>
  </objects>
  <!--objects-->
</spring>
</configuration>

 

 

step3 write the follow codes:

//HelloWorld.cs   

public class HelloWorld : LiveDevTest.IHelloWorld
    {
        public void Hello(string msg)
        {
            Console.WriteLine("I'm in hello :" + msg);
        }
    }

 

//HelloWorld2.cs

using System;
using System.Collections.Generic;
using System.Text;

namespace LiveDevTest
{
    public class HelloWorld2:IHelloWorld
    {
        #region IHelloWorld 成员

        public void Hello(string msg)
        {
            if(string.IsNullOrEmpty(_msg))
                Console.WriteLine("I'm in hello2:" + msg);
            else
                Console.WriteLine("I'm in hello2:" + _msg);
        }

        private string _msg;

        public string Msg
        {
            get { return _msg; }
            set { _msg = value; }
        }
        #endregion
    }
}

 

//IHelloWorld.cs

using System;
namespace LiveDevTest
{
    interface IHelloWorld
    {
        void Hello(string msg);
    }
}

//Program.cs

 

using System;
using System.Collections.Generic;
using System.Text;

using Spring.Context;
using Spring.Context.Support;

namespace LiveDevTest
{
    class Program
    {
        static void Main(string[] args)
        {
            //ioc
            IApplicationContext ctx = ContextRegistry.GetContext();
            //IHelloWorld hello = (IHelloWorld)ctx.GetObject("HelloWorld");           
            //hello.Hello("hello :" + System.DateTime.Now.ToString());

            IHelloWorld h;
            string[] strs = ctx.GetObjectNamesForType(Type.GetType("LiveDevTest.IHelloWorld"));
            for (int i = 0; i < strs.Length; i++)
            {
                h = (IHelloWorld)ctx.GetObject(strs[i]);
                h.Hello("hello :" + System.DateTime.Now.ToString());
            }
   
        }
    }
}
