Unity No Policies

Unity提供了丰富的拦截匹配策略,同时它也提供了ApplyNoPoliciesAttribute用于对特定的成员不应用拦截策略。看一个简单的示例:

 1 public class MyObject
 2 {
 3   [ApplyNoPolicies]
 4   public virtual Int32 DoWork(Int32 i, Char c)
 5   {
 6     return i;
 7   }
 8 
 9   public virtual void DoWork2(Int32 i, Char c)
10   {
11 
12   }
13 
14   public virtual void DoWork3()
15   {
16 
17   }
18 }
19 
20 IUnityContainer unityContainer = new UnityContainer();
21 
22 unityContainer.LoadConfiguration();
23 unityContainer.Configure<Interception>()
24   .AddPolicy(“TypeMatchingRule”)
25   .AddMatchingRule(new TypeMatchingRule(“MyObject”))
26   .AddCallHandler<Log4NetHandler>();
27 unityContainer.RegisterType<MyObject>(
28   new Interceptor<VirtualMethodInterceptor>(),
29   new InterceptionBehavior<PolicyInjectionBehavior>()
30 );
31 
32 MyObject myObject = unityContainer.Resolve<MyObject>();
33 
34 myObject.DoWork(Int32.MaxValue, Char.MaxValue);
35 myObject.DoWork2(Int32.MaxValue, Char.MaxValue);
36 myObject.DoWork3();

MyObject类型的DoWork函数不会被拦截。
