Unity提供了匹配多个Type的规则TypeMatchingRule类型。和TagAttributeMatchingRule的tagToMatch参数一样,TypeMatchingRule的参数typeName一样不支持通配符。看一个简单的示例:
1 public class MyObject 2 { 3 public virtual Int32 DoWork(Int32 i, Char c) 4 { 5 return i; 6 } 7 8 public virtual void DoWork2(Int32 i, Char c) 9 { 10 11 } 12 13 public virtual void DoWork3() 14 { 15 16 } 17 } 18 19 IUnityContainer unityContainer = new UnityContainer(); 20 21 unityContainer.LoadConfiguration(); 22 unityContainer.Configure<Interception>() 23 .AddPolicy(“TypeMatchingRule”) 24 .AddMatchingRule(new TypeMatchingRule(“MyObject”)) 25 .AddCallHandler<Log4NetHandler>(); 26 unityContainer.RegisterType<MyObject>( 27 new Interceptor<VirtualMethodInterceptor>(), 28 new InterceptionBehavior<PolicyInjectionBehavior>() 29 ); 30 31 MyObject myObject = unityContainer.Resolve<MyObject>(); 32 33 myObject.DoWork(Int32.MaxValue, Char.MaxValue); 34 myObject.DoWork2(Int32.MaxValue, Char.MaxValue); 35 myObject.DoWork3();
