安装prism.DryIoc

修改app.xaml

<prism:PrismApplication x:Class="WpfApp3.App"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:local="clr-namespace:WpfApp3"xmlns:prism="http://prismlibrary.com/"><Application.Resources></Application.Resources>
</prism:PrismApplication>

/// <summary>
/// Interaction logic for App.xaml
/// </summary>
public partial class App : PrismApplication
{protected override Window CreateShell(){return Container.Resolve<MainWindow>();}protected override void RegisterTypes(IContainerRegistry containerRegistry){//throw new NotImplementedException();}
}

安装 模板 prism Template pack

DirectoryModuleCatalog、XamlModuleCatalog、ConfigurationModuleCatalog 都间接继承IModuleCatalog

Prism 区域

》》 prism:ViewModelLocator.AutoWireViewModel=“True”，
》》View要和ViewModel自带匹配，不需要 this.DataContext = new ViewModel();
》》需要遵循一个些规定， ViewModels 中的View名称+ViewModel 这种命名规则

<Window x:Class="BlankApp2.Views.MainView"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:prism="http://prismlibrary.com/"prism:ViewModelLocator.AutoWireViewModel="True"Title="{Binding Title}" Height="350" Width="525" ><Grid><Grid.RowDefinitions><RowDefinition Height="50"></RowDefinition><RowDefinition></RowDefinition></Grid.RowDefinitions><StackPanel Orientation="Horizontal" HorizontalAlignment="Right"><Button Content="模块A" Command="{Binding OpenCommand}" CommandParameter="ViewA"></Button><Button Content="模块B" Command="{Binding OpenCommand}" CommandParameter="ViewB"></Button></StackPanel><ContentControl Grid.Row="1" prism:RegionManager.RegionName="ContentRegion" /></Grid>
</Window>

using Prism.Commands;
using Prism.Mvvm;
using Prism.Regions;
using System;namespace BlankApp2.ViewModels
{public class MainViewModel : BindableBase{private string _title = "Prism Application";public string Title{get { return _title; }set { SetProperty(ref _title, value); }}private readonly IRegionManager _regionManager;public MainViewModel(IRegionManager regionManager){this._regionManager = regionManager;this.OpenCommand = new DelegateCommand<string>(Open);}private void Open(string obj){_regionManager.Regions["ContentRegion"].RequestNavigate(obj);}public  DelegateCommand<string> OpenCommand { get; private set; }}
}

using BlankApp2.Views;
using Prism.Ioc;
using System.Windows;namespace BlankApp2
{/// <summary>/// Interaction logic for App.xaml/// </summary>public partial class App{protected override Window CreateShell(){return Container.Resolve<MainView>();}protected override void RegisterTypes(IContainerRegistry containerRegistry){containerRegistry.RegisterForNavigation<ViewA>();           containerRegistry.RegisterForNavigation<ViewB>();//可以不使用默认匹配规则，自己指定对应的上下文//containerRegistry.RegisterForNavigation<ViewA,ViewAViewModel>();//containerRegistry.RegisterForNavigation<ViewA,ViewBViewModel>();}}
}

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

1. 新建wpf应用程序
2. nugut 》》Prism.DryIoc
3. 删除 App.xaml AssembylyInfo.cs MainWindow.xaml 这三个文件，同时把项目修改 类库
4. 新建Views 文件夹 存放 视图文件
5. 新建一个 项目名称+Profile 命名的 类

using ModuleA.Views;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace ModuleA
{public class ModuleAProfile : IModule{public void OnInitialized(IContainerProvider containerProvider){// throw new NotImplementedException();}public void RegisterTypes(IContainerRegistry containerRegistry){//ViewA  是Views下面的 视图文件containerRegistry.RegisterForNavigation<ViewA>();}}
}

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dll

using BlankApp2.Views;using Prism.Ioc;
using Prism.Modularity;using System.Windows;namespace BlankApp2
{/// <summary>/// Interaction logic for App.xaml/// </summary>public partial class App{protected override Window CreateShell(){return Container.Resolve<MainView>();}protected override void RegisterTypes(IContainerRegistry containerRegistry){//containerRegistry.RegisterForNavigation<ViewA>();//containerRegistry.RegisterForNavigation<ViewB>();}protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog){//moduleCatalog.AddModule<StudentProfile>();//moduleCatalog.AddModule<ModuleAProfile>();//moduleCatalog.AddModule<ModuleCProfile>();//base.ConfigureModuleCatalog(moduleCatalog);}protected override IModuleCatalog CreateModuleCatalog(){return new DirectoryModuleCatalog() { 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

<?xml version="1.0" encoding="utf-8" ?>
<configuration><configSections><section name="modules" type="Prism.Modularity.ModulesConfigurationSection, Prism.Wpf" /></configSections><startup></startup><modules><module assemblyFile="ModuleA.dll" moduleType="ModuleA.ModuleAProfile, ModuleA, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" moduleName="ModuleAProfile" startupLoaded="True" /></modules>
</configuration>

xaml 配置文件

<m:ModuleCatalog xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:m="clr-namespace:Prism.Modularity;assembly=Prism.Wpf"><m:ModuleInfo ModuleName="ModuleAProfile" ModuleType="ModuleA.ModuleAProfile, ModuleA, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /></m:ModuleCatalog>

using ModuleA.Views;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace ModuleA
{public class ModuleAProfile : IModule{public void OnInitialized(IContainerProvider containerProvider){// throw new NotImplementedException();var regionManager = containerProvider.Resolve<IRegionManager>();regionManager.RegisterViewWithRegion("ContentRegion", typeof(ViewA));}public void RegisterTypes(IContainerRegistry containerRegistry){//containerRegistry.RegisterForNavigation<ViewA>();}}
}
