使用灵活方便
支持对象与对象之间的依赖
[Component(Named="RunPeople")]
public class RunPeople : IRun
{
public void Do()
{
System.Console.WriteLine("人类跑起来!");
}
}
[Component]
public class Fly
{
[Injection(Named="RunPeople")]
Run run;
public void step1()
{
run.Do();
System.Console.WriteLine("飞行第一步!");
}
}
使用方式，程序入口先初始化DIFactory.Init();
[Injection]
Fly flyObj;
void print(){
DIFactory.Init();
DIFactory.InjectFromObject(this);
flyObj.step1();
}
static void Main(string[] args)
{
DIFactory.Init();
System.Console.WriteLine("Hello World!");
new Program().print();
}
结果
Hello World!
人类跑起来!
飞行第一步!
