Prism.Interactivity: 主要用来截取View即界面的一些处理，而这些功能通过vm 不好实现，只能用 CommandBehaviorBase 来截取处理，特别是在处理界面异常很有用。

定义如下：

  public class ValidationExceptionBehavior : Behavior<FrameworkElement>

{ 

// 方法体

}

使用：

界面错误信息的处理：

  <Interactivity:Interaction.Behaviors>                <common:ValidationExceptionBehavior></common:ValidationExceptionBehavior>

            </Interactivity:Interaction.Behaviors>

键盘事件的处理

   <Interactivity:Interaction.Triggers>

                <Interactivity:EventTrigger EventName="KeyDown">

                    <Interactivity:InvokeCommandAction Command="{Binding ButtonKeyDown}"

                                               CommandParameter="{Binding RelativeSource={RelativeSource  Mode=FindAncestor, AncestorType={x:Type Window}}}"/>

                </Interactivity:EventTrigger>

            </Interactivity:Interaction.Triggers>

注意界面要引用：

xmlns:Interactivity=http://schemas.microsoft.com/expression/2010/interactivity

Prism.Modularity: 模块定义，加载，管理

继承 IModule

 public class PositionModule : IModule

{

  // 其他内容

///必须实现 Initialize ,注册该模块中使用的服务,vm 等。提供主程序中使用。

    public void Initialize()

        {    

       .....

            this.container.RegisterType<IOrdersViewModel, OrdersViewModel>();

            this.container.RegisterType<IOrdersView, OrdersView>();

            this.container.RegisterType<IOrderCompositeViewModel, OrderCompositeViewModel>();

            this.container.RegisterType<IPositionSummaryViewModel, PositionSummaryViewModel>();

            this.container.RegisterType<IPositionPieChartViewModel, PositionPieChartViewModel>();

            this.regionManager.RegisterViewWithRegion(RegionNames.MainRegion,

                                                       () => this.container.Resolve<PositionSummaryView>());

            this._ordersController = this.container.Resolve<OrdersController>();

        }

}

主程序中使用方法：

在 Bootstrapper 中使用：

public class StockTraderRIBootstrapper : UnityBootstrapper

    {

        protected override void ConfigureModuleCatalog()

        {

            base.ConfigureModuleCatalog();

            ModuleCatalog moduleCatalog = (ModuleCatalog)this.ModuleCatalog;                   moduleCatalog.AddModule(typeof(StockTraderRI.Modules.Position.PositionModule));                     moduleCatalog.AddModule(typeof(StockTraderRI.Modules.News.NewsModule));

        }

        protected override DependencyObject CreateShell()

        {

            // Use the container to create an instance of the shell.

            Shell view = this.Container.TryResolve<Shell>();

            view.DataContext = new ShellViewModel();

            return view;

        }

        protected override void InitializeShell()

        {

            base.InitializeShell();

            App.Current.MainWindow = (Window)this.Shell;

            App.Current.MainWindow.Show();

        }

        protected override Prism.Regions.IRegionBehaviorFactory ConfigureDefaultRegionBehaviors()

        {

            var factory = base.ConfigureDefaultRegionBehaviors();

            return factory;

        }

}

 这是通过代码实现的，也可以通过 xml 配置文件实现

protected override IModuleCatalog CreateModuleCatalog() {     return ModuleCatalog.CreateFromXaml(new Uri("/MyProject;component/ModulesCatalog.xaml", UriKind.Relative)); }
