本文详细介绍了一种基于WPF的模块化应用程序开发方法。通过创建一个简单的“Hello World”模块，展示了如何从新建项目开始，逐步实现模块注册与加载的过程。文章涵盖了App.xaml及CS文件的配置、Shell窗口的设计、用户自定义控件的建立、模块类的编写以及Bootstrapper类的实现。

1 新建wpf项目，修改App.xaml

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

2 修改App.xaml.cs

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Threading.Tasks;
using System.Windows;

namespace MyHelloWorld
{
    /// <summary>
    /// App.xaml 的交互逻辑
    /// </summary>
    public partial class App : Application
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            Bootstrapper bootstrapper = new Bootstrapper();
            bootstrapper.Run();
        }
    }
}

3 新建shell.xaml

<Window x:Class="HelloWorld.Shell"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:cal="http://www.codeplex.com/prism"
    Title="Hello World" Height="300" Width="300">
    <ItemsControl Name="MainRegion" cal:RegionManager.RegionName="MainRegion" />
</Window>

4新建wpf库项目，在其中新建View目录新建用户自定义控件

<UserControl x:Class="HelloWorldModule.Views.HelloWorldView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Grid>
        <TextBlock Text="Hello World" Foreground="Green" HorizontalAlignment="Center" VerticalAlignment="Center" FontFamily="Calibri" FontSize="24" FontWeight="Bold"></TextBlock>
    </Grid>
</UserControl>

5 新建Module类

using Microsoft.Practices.Prism.Modularity;
using Microsoft.Practices.Prism.Regions;

namespace HelloWorldModule
{
    public class HelloWorldModule : IModule
    {
        private readonly IRegionViewRegistry regionViewRegistry;

        public HelloWorldModule(IRegionViewRegistry registry)
        {
            this.regionViewRegistry = registry;   
        }

        public void Initialize()
        {
            regionViewRegistry.RegisterViewWithRegion("MainRegion", typeof(Views.HelloWorldView));
        }
    }
}

6 在主项目中新建Bootstrapper类

using System.Windows;
using Microsoft.Practices.Prism.Modularity;
using Microsoft.Practices.Unity;
using Microsoft.Practices.Prism.UnityExtensions;

namespace HelloWorld
{
    class Bootstrapper : UnityBootstrapper
    {
        protected override DependencyObject CreateShell()
        {
            return this.Container.Resolve<Shell>();
        }

        protected override void InitializeShell()
        {
            base.InitializeShell();

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

        protected override void ConfigureModuleCatalog()
        {
            base.ConfigureModuleCatalog();

            ModuleCatalog moduleCatalog = (ModuleCatalog)this.ModuleCatalog;
            moduleCatalog.AddModule(typeof(HelloWorldModule.HelloWorldModule));
        }

        
    }
}
