Prism中的containerRegister¹

实现功能

通过点击不同的Button，实现显示不同的界面

思路

• 新建项-WPF-删除APP，完成两个模块，两个模块中写上约定
• Prism WPF模板，完成Views中UI部分
• 在Views中用两种不同的注册方式完成功能实现

模块

ModuleA

新建WPF，命名ModuleA，删除APP

定义模块A

• 新建文件夹Views,新建类，命名ViewA

约定文件

新建类，命名ModuleAProfile

实现接口IModule​

  public class ModuleAProfile : IModule

写约，写上容器服务

{//约定，容器服务public class ModuleAProfile : IModule{public void OnInitialized(IContainerProvider containerProvider){}public void RegisterTypes(IContainerRegistry containerRegistry){containerRegistry.RegisterForNavigation();}}
}

‍

ModuleB

同ModuleA​

Views

MainWindow.xaml

打格子

写两个Button

模块内容 介绍ContentControl²

MainWindow.xaml.cs

using System.Windows;namespace WpfApp3.Views
{/// 
/// Interaction logic for MainWindow.xaml/// 
public partial class MainWindow : Window{public MainWindow(){InitializeComponent();}}
}

App.xaml

这里有两种方式注册模块，一种是通过引用，一种是写文件位置

引用

添加ConfigureModuleCatalog方法

添加名称空间

using ModuleA;
using ModuleB;

namespace WpfApp3
{/// 
/// Interaction logic for App.xaml/// 
public partial class App{protected override Window CreateShell(){return Container.Resolve();}protected override void RegisterTypes(IContainerRegistry containerRegistry){}protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog){moduleCatalog.AddModule();moduleCatalog.AddModule();base.ConfigureModuleCatalog(moduleCatalog);}}
}

通过写文件位置的方式

• 去掉WpfApp3中的引用

• 将ModuleA.dll​，​ ModuleB.dll​文件拷贝到WpfApp3.dll​所在文件夹下的Modules​文件夹，若没有，则新建

添加ConfigureModuleCatalog方法

using Prism.Ioc;
using Prism.Modularity;
using System.Windows;
using WpfApp3.Views;namespace WpfApp3
{/// 
/// Interaction logic for App.xaml/// 
public partial class App{protected override Window CreateShell(){return Container.Resolve();}protected override void RegisterTypes(IContainerRegistry containerRegistry){}protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog){}protected override IModuleCatalog CreateModuleCatalog(){return new DirectoryModuleCatalog(){ModulePath =@".\Modules" };}}
}

ViewModels

MainWindowViewModel.cs

using Prism.Commands;
using Prism.Mvvm;
using Prism.Regions;namespace WpfApp3.ViewModels
{public class MainWindowViewModel : BindableBase{private string _title = "Prism Application";public string Title{get { return _title; }set { SetProperty(ref _title, value); }}public DelegateCommand OpenCommand { get; private set; }public MainWindowViewModel(){}private readonly IRegionManager regionManager;public MainWindowViewModel(IRegionManager regionManger){OpenCommand = new DelegateCommand(Open);this.regionManager = regionManger;}private void Open(string obj){//首先通过IregionManager接口获取全局定义的区域//往这个区域动态的去设置内容//设置内容的方式是依赖注入regionManager.Regions["ContentRegion"].RequestNavigate(obj);}}
}
