1. 代码-test.cs

   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

<?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>
