Regions.NET

一个轻量级、Prism 风格的 WPF 区域（Region）导航框架，支持 DI、导航历史、生命周期事件、redirect 语义等。

特性

  • 支持 WPF XAML 区域声明（propdp）
  • 支持 DI 容器（Microsoft.Extensions.DependencyInjection）自动解析页面
  • 支持导航历史（GoBack/GoForward）
  • 支持 redirect 语义（类比 uniapp 的 redirectTo）
  • 支持 INavigationAware 生命周期事件（OnNavigatedFrom/OnNavigatedTo）
  • 支持页面持有策略（AddSingleton/AddScoped/AddTransient）

页面策略

  • AddSingleton：页面实例全局唯一，始终持有，即使重定向导航也不会释放。
  • AddScoped：同一区域页面唯一，回退导航/前进导航都能维持页面实例。
  • AddTransient：每次导航新建实例，回退后不再持有，重定向导航后页面可被释放。

区域适配

支持多种容器类型的区域适配：可扩展适配 ContentControl、ItemsControl、TabControl 等，注册机制自动关联容器与适配器，满足不同 UI 需求。

src/Regions.WPF/RegionAdapter.cs 是本库的核心组件之一，负责将区域（Region）机制适配到不同类型的容器控件（如 ContentControl、ItemsControl、TabControl 等）。

通过自定义 RegionAdapter，可以让区域管理器灵活支持多种 UI 容器，极大提升了扩展性和兼容性。

快速用法

1. 注册服务

var services = new ServiceCollection();
services.AddSingleton<IRegionManager, RegionManager>();
services.AddSingleton<IRegionNavigationJournal, RegionNavigationJournal>();
services.AddSingleton<IRegionNavigationService, RegionNavigationService>();
services.AddTransient<PageA>(); // 或 AddScoped/AddSingleton
services.AddTransient<PageB>();

2. XAML 声明 Region

  • 可使用 RegionName 附加属性声明 Region。
<ContentControl regions:RegionManager.RegionName="MainRegion" />

添加的 Region 可以用 IRegionManager.RemoveRegion / IRegionManager.ClearRegions 手动清理。

  • 可使用 AddToRegion 附加属性将带有名称的控件添加到指定 Region。
<Grid regions:RegionManager.RegionName="MainRegion">
    <Grid regions:RegionManager.AddToRegion="MainRegion,/ContentRegion"
              regions:RegionManager.RegionName="ContentRegion" />
</Grid>

3. 导航页面

// 普通导航
_regionManager.RequestNavigate("MainRegion", new Uri("/PageA", UriKind.Relative));
// 重定向导航
_regionManager.RequestRedirect("MainRegion", new Uri("/PageB", UriKind.Relative));
// 回退导航
_regionManager.RequestGoBack("MainRegion");

4. 页面生命周期

页面或 ViewModel 实现 INavigationAware：

public class PageA : UserControl, INavigationAware
{
   public void OnNavigatedFrom(object? parameter = null) { /* 离开时 */ }
   public void OnNavigatedTo(object? parameter = null) { /* 进入时 */ }
}

适用场景

  • 需要 MVVM/DI/导航解耦的 WPF 应用
  • 需要页面生命周期、导航历史、redirect 等高级导航特性的桌面应用
