使用Unity Application block实现Ioc

1. 代码-test.cs

   Code

   */
   
   using System;
   using Microsoft.Practices.Unity;
   using Microsoft.Practices.Unity.Configuration;
   using System.Configuration;
   namespace KingRi.Test
   {
    public interface IDataBase
    {
    void Save();
    }
    public class SqlServer : IDataBase
    {
    public void Save()
    {
    Console.WriteLine("保存到Sql Server!");
    }
    }
    public class Oracle : IDataBase
    {
    public void Save()
    {
    Console.WriteLine("保存到Oracle");
    }
    }
    public class Factory
    {
    private IDataBase db;
    [Dependency]
    public IDataBase Db
    {
    get
    {
    return db;
    }
    set
    {
    this.db = value;
    }
    }
    public void Save()
    {
    db.Save();
    }
    public Factory()
    {
    
    }
    }
    public class Client
    {
    static void Main()
    {
    //1, 创建容器
    IUnityContainer container = new UnityContainer();
   
    //2, 获取配置信息
    UnityConfigurationSection section = ConfigurationManager.GetSection("unity") as UnityConfigurationSection;
    
    //3, 使用配置信息设置容器
    section.Containers.Default.Configure(container);
    
    //4, 获取对象
    Factory obj = container.Resolve<Factory>();
   
    obj.Save();
    Console.ReadLine();
    }
    }
   }

2. 配置文件-test.exe.config

Code

    
      <?xml version="1.0" encoding="utf-8" ?>
<configuration>
 <configSections>
 <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration" />
 </configSections>
 <unity>
 <containers>
 <container>
 <types>
 <type type="KingRi.Test.IDataBase, test" mapTo="KingRi.Test.SqlServer, test" />
 </types>
 </container>
 </containers>
 </unity>
</configuration>
