prism WPF 模块

模块 DLL

ModuleA 和 ModuleB 都要安装 Prism.Unity

引用方式1 项目引用

直接 在引用中添加项目引用

App.xaml.cs 添加模块 ConfigureModuleCatalog

using ModuleA;
using ModuleB;
using Prism.Ioc;
using Prism.Modularity;
using Prism.Unity;
using PrismWpfApp.ViewModels;
using PrismWpfApp.Views;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Threading.Tasks;
using System.Windows;

namespace PrismWpfApp
{
    /// <summary>
    /// App.xaml 的交互逻辑
    /// </summary>
    public partial class App : PrismApplication
    {
        /// <summary>
        /// 提供主窗口的对象
        /// </summary>
        /// <returns></returns>
        /// <exception cref="NotImplementedException"></exception>
        protected override Window CreateShell()
        {
            //打开第一个窗口 ModuleWindow
            //return Container.Resolve<MainWindow>();
            return Container.Resolve<ModuleWindow>();
            //return new MainWindow();
        }

        /// <summary>
        /// 业务中所有需要注入的对象，在这个方法里注册
        /// </summary>
        /// <param name="containerRegistry"></param>
        /// <exception cref="NotImplementedException"></exception>
        protected override void RegisterTypes(IContainerRegistry containerRegistry)
        {
            //注册 导航 RegisterForNavigation
            containerRegistry.RegisterForNavigation<UserControlA>();
            containerRegistry.RegisterForNavigation<UserControlB>();
            containerRegistry.RegisterForNavigation<UserControlC>();
        }

        /// <summary>
        /// 添加模块
        /// </summary>
        /// <param name="moduleCatalog"></param>
        protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog)
        {
            moduleCatalog.AddModule<ModuleAProfile>();
            moduleCatalog.AddModule<ModuleBProfile>();
            base.ConfigureModuleCatalog(moduleCatalog);
        }

        //protected override void OnStartup(StartupEventArgs e)
        //{
        //    base.OnStartup(e);

        //    if (new LoginWindow().ShowDialog() == true)
        //    {
        //        new MainWindow().ShowDialog();
        //    }
        //    Application.Current.Shutdown();
        //}
    }
}

引用方式2 通过Modules目录动态注册

App.xaml.cs 创建模块 CreateModuleCatalog()

using Prism.Ioc;
using Prism.Modularity;
using Prism.Unity;
using PrismWpfApp.ViewModels;
using PrismWpfApp.Views;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Threading.Tasks;
using System.Windows;

namespace PrismWpfApp
{
    /// <summary>
    /// App.xaml 的交互逻辑
    /// </summary>
    public partial class App : PrismApplication
    {
        /// <summary>
        /// 提供主窗口的对象
        /// </summary>
        /// <returns></returns>
        /// <exception cref="NotImplementedException"></exception>
        protected override Window CreateShell()
        {
            //打开第一个窗口 ModuleWindow
            //return Container.Resolve<MainWindow>();
            return Container.Resolve<ModuleWindow>();
            //return new MainWindow();
        }

        /// <summary>
        /// 业务中所有需要注入的对象，在这个方法里注册
        /// </summary>
        /// <param name="containerRegistry"></param>
        /// <exception cref="NotImplementedException"></exception>
        protected override void RegisterTypes(IContainerRegistry containerRegistry)
        {
            //注册 导航 RegisterForNavigation
            containerRegistry.RegisterForNavigation<UserControlA>();
            containerRegistry.RegisterForNavigation<UserControlB>();
            containerRegistry.RegisterForNavigation<UserControlC>();
        }

        /// <summary>
        /// 添加模块(代码引用)
        /// </summary>
        /// <param name="moduleCatalog"></param>
        //protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog)
        //{
        //    moduleCatalog.AddModule<ModuleAProfile>();
        //    moduleCatalog.AddModule<ModuleBProfile>();
        //    base.ConfigureModuleCatalog(moduleCatalog);
        //}

        /// <summary>
        /// 创建模块
        /// </summary>
        protected override IModuleCatalog CreateModuleCatalog()
        {
            return new DirectoryModuleCatalog() { ModulePath = @".\Modules" };
        }

        //protected override void OnStartup(StartupEventArgs e)
        //{
        //    base.OnStartup(e);

        //    if (new LoginWindow().ShowDialog() == true)
        //    {
        //        new MainWindow().ShowDialog();
        //    }
        //    Application.Current.Shutdown();
        //}
    }
}

ModuleAProfile

using ModuleA.Views;
using Prism.Ioc;
using Prism.Modularity;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ModuleA
{
    /// <summary>
    /// 模块要实现 IModule 接口 
    /// </summary>
    public class ModuleAProfile : IModule
    {
        public void OnInitialized(IContainerProvider containerProvider)
        {
            
        }

        /// <summary>
        /// 模块 服务注入
        /// </summary>
        /// <param name="containerRegistry"></param>
        public void RegisterTypes(IContainerRegistry containerRegistry)
        {
            //导航
            containerRegistry.RegisterForNavigation<UserControl1>();
        }
    }
}
