微软IOC容器Unity简单代码示例2-配置文件方式详解编程语言

@(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(); 
        } 
    } 
}
