public static void BuildMvcContainer() { var builder = new ContainerBuilder(); var assemblys = AppDomain.CurrentDomain.GetAssemblies().ToList(); //拆分DLL后需要注册，需要注入的DLL Assembly[] asm = GetAllAssembly("*.Controllers.dll").ToArray(); builder.RegisterAssemblyTypes(asm); //读取web.config中配置的值 builder.RegisterModule(new ConfigurationSettingsReader("autofac")); var container = builder.Build(); DependencyResolver.SetResolver(new AutofacDependencyResolver(container)); } #region 加载程序集 private static List<Assembly> GetAllAssembly(string dllName) { List<string> pluginpath = FindPlugin(dllName); var list = new List<Assembly>(); foreach (string filename in pluginpath) { try { string asmname = Path.GetFileNameWithoutExtension(filename); if (asmname != string.Empty) { Assembly asm = Assembly.LoadFrom(filename); list.Add(asm); } } catch (Exception ex) { Console.Write(ex.Message); } } return list; } //查找所有插件的路径 private static List<string> FindPlugin(string dllName) { List<string> pluginpath = new List<string>(); string path = AppDomain.CurrentDomain.BaseDirectory; string dir = Path.Combine(path, "bin"); string[] dllList = Directory.GetFiles(dir, dllName); if (dllList.Length > 0) { pluginpath.AddRange(dllList.Select(item => Path.Combine(dir, item.Substring(dir.Length + 1)))); } return pluginpath; } #endregion上面的代码就是注册的代码，我是在MVC4使用，写完之后再Global.asax中的Application_Start调用，确保启动应用后执行
然后是web.config中配置
<autofac configSource="Configuration\autofac.config" />
我web.config中引用一个文件，详细看我之前的博文
<?"1.0" encoding="utf-8"?><autofac> <components> <component type="Cactus.Service.TestServer, Cactus.Service" service="Cactus.IService.TestInterface,Cactus.IService" /> <component type="Cactus.Service.SiteConfigService, Cactus.Service" service="Cactus.IService.ISiteConfigService,Cactus.IService" /> <component type="Cactus.Service.ActionGroupServer, Cactus.Service" service="Cactus.IService.IActionGroupServer,Cactus.IService" /> <component type="Cactus.Service.ActionServer, Cactus.Service" service="Cactus.IService.IActionServer,Cactus.IService" /> <component type="Cactus.Service.RoleServer, Cactus.Service" service="Cactus.IService.IRoleServer,Cactus.IService" /> <component type="Cactus.Service.UserServer, Cactus.Service" service="Cactus.IService.IUserServer,Cactus.IService" /> </components></autofac>
然后在autofac.config中注册服务，type是实现的server，service是接口
在MVC中的使用，根据的是构造函数注入
public class AdminLoginController : Controller { public readonly IUserServer userServer; public AdminLoginController(IUserServer userServer) { this.userServer = userServer; } public ActionResult Index() { userServer.xxxxx//随便写 return View(); }} 属性注入可以参考这篇文章http://www.cnblogs.com/peteryu007/p/3449315.html
