如何配置Unity的Behaviors for Interception
继续前一篇实现的NotifyPropertyChangedBehavior,如何在配置文件中添加:
<?xml version=”1.0″ encoding=”utf-8″ ?> <configuration> <configSections> <section name=”unity” type=”Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration”/> </configSections> <unity xmlns=”http://schemas.microsoft.com/practices/2010/unity”> <sectionExtension type=”Microsoft.Practices.Unity.InterceptionExtension.Configuration.InterceptionConfigurationExtension, Microsoft.Practices.Unity.Interception.Configuration” /> <assembly name=”mscorlib, 2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089″ /> <assembly name=”UnityTest5″ /> <namespace name=”System.ComponentModel” /> <namespace name=”UnityTest5″ /> <container> <extension type=”Interception” /> <register type=”MainViewModel”> <interceptor type=”VirtualMethodInterceptor” /> <addInterface type=”INotifyPropertyChanged” /> <interceptionBehavior type=”NotifyPropertyChangedBehavior” /> </register> </container> </unity> </configuration>
默认Unity的配置无法识别interceptor,需要在unity配置节中添加一个sectionExtension,由InterceptionConfigurationExtension处理(Microsoft.Practices.Unity.Interception.Configuration.dll)。
代码中使用:
1 IUnityContainer unityContainer = new UnityContainer(); 2 3 unityContainer.LoadConfiguration(); 4 5 MainViewModel viewModel = unityContainer.Resolve<MainViewModel>(); 6 7 ((INotifyPropertyChanged)viewModel).PropertyChanged += new PropertyChangedEventHandler((sender, e) => Console.WriteLine(e.PropertyName)); 8 9 viewModel.Name = “hello, world”;
