wpf prism 《1》、区域 、模块化 StackPanel实现区域适配器

实现自定义区域适配器 (Region Adapter)第一步创建自定义适配器类# 第一步创建自定义适配器类 StackPanelRegionAdapter 让它继承自 RegionAdapterBaseTusingPrism.Regions;usingSystem;usingSystem.Collections.Generic;usingSystem.Collections.Specialized;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;usingSystem.Windows;usingSystem.Windows.Controls;namespaceBlankApp1{internalclassStackPanelRegionAdapter:RegionAdapterBaseStackPanel{publicStackPanelRegionAdapter(IRegionBehaviorFactoryregionBehaviorFactory):base(regionBehaviorFactory){}// 核心方法将区域和StackPanel关联起来protectedoverridevoidAdapt(IRegionregion,StackPanelregionTarget){// 订阅区域中视图集合的变化事件region.Views.CollectionChanged(sender,e){// 当有视图被添加时将其添加到StackPanel中if(e.ActionNotifyCollectionChangedAction.Add){foreach(FrameworkElementelementine.NewItems){regionTarget.Children.Add(element);}}// 当有视图被移除时将其从StackPanel中移除elseif(e.ActionNotifyCollectionChangedAction.Remove){foreach(FrameworkElementelementine.OldItems){if(regionTarget.Children.Contains(element))regionTarget.Children.Remove(element);}}};}protectedoverrideIRegionCreateRegion(){//创建Region实例AllActiveRegion表示所有视图同时激活returnnewAllActiveRegion();}}}第二步注册自定义适配器usingSystem.Windows;usingSystem.Windows.Controls;usingBlankApp1.Views;usingPrism.Ioc;usingPrism.Regions;namespaceBlankApp1{/// summary/// Interaction logic for App.xaml/// /summarypublicpartialclassApp{protectedoverrideWindowCreateShell(){returnContainer.ResolveMainWindow();}protectedoverridevoidRegisterTypes(IContainerRegistrycontainerRegistry){}# 注册自定义适配器类protectedoverridevoidConfigureRegionAdapterMappings(RegionAdapterMappingsregionAdapterMappings){base.ConfigureRegionAdapterMappings(regionAdapterMappings);// 注册自定义适配器 会通过 Prism 的依赖注入容器来获取适配器实例regionAdapterMappings.RegisterMapping(typeof(StackPanel),Container.ResolveStackPanelAdapter());}}}第三步在 XAML 中使用Windowx:ClassBlankApp1.Views.MainWindowxmlnshttp://schemas.microsoft.com/winfx/2006/xaml/presentationxmlns:xhttp://schemas.microsoft.com/winfx/2006/xamlxmlns:prismhttp://prismlibrary.com/prism:ViewModelLocator.AutoWireViewModelTrueTitle{Binding

viewmodelusingPrism.Mvvm;usingPrism.Regions;namespaceBlankApp1.ViewModels{publicclassMainWindowViewModel:BindableBase{privatestring_titlePrism Application;privateIRegionManager_regionManager;publicstringTitle{get{return_title;}set{SetProperty(ref_title,value);}}publicMainWindowViewModel(IRegionManagerregionManager){this._regionManagerregionManager;# UserControl1 用户控件regionManager.RegisterViewWithRegion(ct,typeof(UserControl1));}}}模块化 《1》 强引用》》》通过prism Blank APP WPF 创建一个wpf应用》》》新建模块步骤新建wpf应用程序nugut 》》Prism.DryIoc删除 App.xaml AssembylyInfo.cs MainWindow.xaml 这三个文件同时把项目修改 类库新建Views 文件夹 存放 视图文件新建一个 项目名称Profile 命名的 类usingModuleA.Views;usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;namespaceModuleA{publicclassModuleAProfile:IModule{publicvoidOnInitialized(IContainerProvidercontainerProvider){// throw new NotImplementedException();}publicvoidRegisterTypes(IContainerRegistrycontainerRegistry){//ViewA 是Views下面的 视图文件containerRegistry.RegisterForNavigationViewA();}}}需要在主程序 引用模块模块化 《2》 利用目录不需要引用这些模块的dll上面的方式需要引用dllusingBlankApp2.Views;usingPrism.Ioc;usingPrism.Modularity;usingSystem.Windows;namespaceBlankApp2{/// summary/// Interaction logic for App.xaml/// /summarypublicpartialclassApp{protectedoverrideWindowCreateShell(){returnContainer.ResolveMainView();}protectedoverridevoidRegisterTypes(IContainerRegistrycontainerRegistry){//containerRegistry.RegisterForNavigationViewA();//containerRegistry.RegisterForNavigationViewB();}protectedoverridevoidConfigureModuleCatalog(IModuleCatalogmoduleCatalog){//moduleCatalog.AddModuleStudentProfile();//moduleCatalog.AddModuleModuleAProfile();//moduleCatalog.AddModuleModuleCProfile();//base.ConfigureModuleCatalog(moduleCatalog);}protectedoverrideIModuleCatalogCreateModuleCatalog(){returnnewDirectoryModuleCatalog(){ModulePath.\Modules};}}}模块化 配置文件的方式可以使用App.config进行配置也可以使用xml文件的方式。 都需要把模块dll引入主程序 添加 配置文件app.config?xmlversion1.0encodingutf-8?configurationconfigSectionssectionnamemodulestypePrism.Modularity.ModulesConfigurationSection,
