@(编程)

1. 通过Nuget下载Unity

这个就不介绍了

2. 接口代码

namespace UnityDemo

{

    interface ILogIn

    {

        void Login();

    }

}

namespace UnityDemo

{

    interface IUser

    {

        string GetUserName();

    }

}

3. 实现代码

using Microsoft.Practices.Unity;

using System;

namespace UnityDemo

{

    class LogInImpl : ILogIn

    {

        [Dependency]

        public IUser userOper { get; set; }

        public void Login()

        {

            Console.WriteLine(this.userOper.GetUserName());

        }

    }

}

namespace UnityDemo

{

    class UserImpl:IUser

    {

        public string GetUserName()

        {

            return "keke";

        }

    }

}

4. 配置文件

<?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 name="defaultContainer">

        <register type="UnityDemo.ILogIn,UnityDemo" mapTo="UnityDemo.LogInImpl,UnityDemo" />

        <register type="UnityDemo.IUser,UnityDemo" mapTo="UnityDemo.UserImpl,UnityDemo" />

      </container>

    </containers>

  </unity>

</configuration>

5. 调用代码

using Microsoft.Practices.Unity;

using Microsoft.Practices.Unity.Configuration;

using System;

using System.Configuration;

namespace UnityDemo

{

    class Program

    {

        static void Main(string[] args)

        {

            IUnityContainer container = new UnityContainer();

            UnityConfigurationSection configuration = ConfigurationManager.GetSection(UnityConfigurationSection.SectionName)

            as UnityConfigurationSection;

            configuration.Configure(container, "defaultContainer");

            var item = container.Resolve<ILogIn>();

            item.Login();

            Console.Read();

        }

    }

}
