.NET Unity IOC框架使用实例详解_实用技巧_

 /// Unity IOC单例模式 ///

 public interface IExampleClass { void DoHelloWord(); } 

 public class ExampleClass : IExampleClass { public void DoHelloWord() { Console.WriteLine("Hello Word!"); } } 

 public class DIExampleClass { //属性注入 [Dependency] public IExampleClass example { get; set; } private IExampleClass testInject; public void DoWork() { example.DoHelloWord(); testInject.DoHelloWord(); } //方法注入 [InjectionMethod] public void Initialize(IExampleClass instance) { testInject = instance; } } 

 class Program { static void Main(string[] args) { //var dao = UnitySingleton.GetInstanceDAL(); var dao = UnitySingleton.GetInstanceDAL(); dao.DoWork(); Console.ReadLine(); } }
