前些天，参与了公司内部小组的一次技术交流，主要是针对《IOC与AOP》，本着学而时习之的态度及积极分享的精神，我就结合一个小故事来初浅地剖析一下我眼中的“IOC前世今生”，以方便初学者能更直观的来学习与理解IOC！也作抛砖引玉之用。
（虽说故事中的需求有点小，但看客可在脑海中尽量把他放大，想象成一个很大的应用系统）
一、IOC雏形
1、程序V1.0
话说，多年以前UT公司提出一个需求，要提供一个系统，其中有个功能可以在新春佳节之际给公司员工发送一封邮件。邮件中给大家以新春祝福，并告知发放一定数额的过节费。
经分析，决定由张三、李四和王五来负责此系统的开发。
其中：由张三负责业逻辑控制模块 LogicController的开发,此处简化为UT.LogicController.exe ；由李四负责祝福消息管理类（GreetMessageService），并集成到组件 UT.MessageService.dll中；由王五负责邮件功能帮助类（EmailHelper），并提供组件 UT.Email.dll。

李四消息管理模块核心代码如下

greetTool.Send(message);

张三业务集成模块核心代码如下：
string message = "新年快乐！过节费5000.";
MessageService.GreetMessageService service = new MessageService.GreetMessageService();
service.Greet(message);
三人经过一个月的艰苦奋战，终于大功告成，系统也在春节其间成功发出问候信。企业如此关怀，给员工带来无比的温暖，因此深受全体员工好评！
春节过后，相应的功能也移植到了与“UT公司”相关的“UT编辑部”和“UT房产”类似的应用当中，并在后继的“元宵”、“端午”、“中秋”等节日中得以广泛应用。
又是一个年关将至……
说真的，过节费的多少，有时可能直接影响整个假日的行程安排、从而影响假日的整体质量，因此部门领导高度重视。而邮件通知的方式，在边远山区常常因为受网 络环境的影响而无法正常收取，许多在外过年的同事对此颇有微词。后经多方考证，决得采用当下非常主流的电话语言播报的方式进行通知。
于是乎，张三、李四、王五又忙起来了。但李四，却有点头疼了，因为他的模块现在不仅在“UT公司”内部使用，而且还在“UT编辑部”和“UT房产”也都有独立运行。如何让此处变化影响最小，就得费点脑筋。为了达到较好的效果，李四决定按以下方式进行整改。
①、初始设计方案如下：

首先为了能让不同“祝福方式”能有效替换，决定以“面向接口”的方式来进行分离。
同时，让EmailHelper的邮件通知类和TelephoneHelper的语音播报类都实现此接口。核心代码如下：
public interface ISendable
{
void Send(string message);
} public class EmailHelper : ISendable
{
public void Send(string message)
{
Console.Write("Frome email: " + message);
}
} public class TelephoneHelper : ISendable
{
public void Send(string message)
{
Console.Write("Frome telephone: " + message);
}
}
再者，为了方便兼容新旧产品，要求Controller决定当前采用什么方式进行通信，并以参数方式传给消息管理模块，核心代码如下：
public enum SendToolType
{
Email,
Telephone,
}
【备注】:上述代码，并不是一个优秀的设计，在后继的优化方案当中将被去除。
public class GreetMessageService
{
ISendable greetTool; public GreetMessageService(SendToolType sendToolType)
{
if (sendToolType == SendToolType.Email)
{
greetTool = new UT.EmailV20.EmailHelper();
}
else if (sendToolType == SendToolType.Telephone)
{
greetTool = new UT.TelephoneV20.TelephoneHelper();
}
} public void Greet(string message)
{
greetTool.Send(message);
}
}
【备注】:上述代码，并不是一个优秀的设计，在后继的优化方案当中将被优化。
最后，业务集成模块结合具体业务需求进行适当的调整，核心代码如下：
string message = "新年快乐！过节费5000.";
GreetMessageService service = new GreetMessageService(SendTool.Telephone);
service.Greet(message);
