一、简介
Castle是.net平台上的一个开源项目,为企业级开发和WEB应用程序开发提供完整的服务,用于提供IOC的解决方案.IOC被称为控制反转或者依赖注入(Dependency Injection)。
Windsor是Castle 的一个IOC容器。它构建于MicroKernel之上,功能非常之强大,能检测类并了解使用这些类时需要什么参数,检测类型和类型之间工作依赖性,并提供服务或者发生错误时提供预警的机制。

二、实例
1.创建项目
在程序包管理器控制台引用Castle.Windsor
Install-Package Castle.Windsor -Version 4.1.0
2.创建类库Business,并在web项目引用,新建接口IUserService和实现类UserService
public interface IUserService { string Display(string mes); } public class UserService : IUserService { public string Display(string mes) { return "User say:" + mes; } }
3.添加安装类
安装的配置比较简单,无非是寻找安装类,并执行安装并获取容器,所有的安装类都需要继承自IWindsorInstaller,添加CustomMvcInstaller ,如下:
namespace MvcWeb.CastleWindsor { public class CustomMvcInstaller : IWindsorInstaller { public void Install(IWindsorContainer container, IConfigurationStore store) { container.Register( Component.For<IUserService>().ImplementedBy<UserService>() ); } } public class WindsorInit { private static WindsorContainer _container; public static WindsorContainer GetContainer() { if (_container == null) { _container = new WindsorContainer(); _container.Install( FromAssembly.This() ); } return _container; } public void CloseContex() { _container.Dispose(); } } }
4.修改home控制器
public class HomeController : Controller { private IUserService _userService; public HomeController() { WindsorContainer container = WindsorInit.GetContainer(); _userService = container.Resolve<IUserService>(new Arguments(new { })); } public ActionResult Index() { ViewBag.Name = _userService.Display("I am coming by Windsor"); return View(); }
index.cshtml修改如下
<div class="jumbotron"> <h1>ASP.NET </h1> <h3>@ViewBag.Name </h3> .......
