.NET Unity IOC框架的使用实例，具体内容如下
1.IOC简介
IOC(Inversion of Control)， 控制反转
DI (Dependency Injection)，依赖注入
IOC的基本概念是：不创建对象，但是描述创建它们的方式。在代码中不直接与对象和服务连接，但在配置文件中描述哪一个组件需要哪一项服务。容器负责将这些联系在一起。
2.Unity引入
3.创建单例模式容器类
using Microsoft.Practices.Unity;
using Microsoft.Practices.Unity.Configuration;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace UnityIocTest
{
/// <summary>
/// Unity IOC单例模式
/// </summary>
public class UnitySingleton
{
//单例
private static UnitySingleton instance;
//ioc容器
public IUnityContainer container;
//获取单例
public static UnitySingleton getInstance()
{
if (instance == null || instance.container == null)
{
string configFile = "Unity.config";
var fileMap = new ExeConfigurationFileMap { ExeConfigFilename = configFile };
//从config文件中读取配置信息
Configuration configuration = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
//获取指定名称的配置节
UnityConfigurationSection section = (UnityConfigurationSection)configuration.GetSection("unity");
instance = new UnitySingleton()
{
//container = new UnityContainer().LoadConfiguration((UnityConfigurationSection)ConfigurationManager.GetSection("unity"), "MyContainer")
container = new UnityContainer().LoadConfiguration(section, "MyContainer")
//container = new UnityContainer()
};
//instance.container.RegisterType<IExampleClass, ExampleClass>();
}
return instance;
}
//IOC注入实体
public static T GetInstanceDAL<T>()
{
return getInstance().container.Resolve<T>();
}
}
}
