03、CustomRegions

　　　　1、将App.xaml中的StartupUri="MainWindow.xaml"删除。

　　2、使用NuGet安装Prism.Wpf、Prism.Core、Prism.Unity。

　　3、添加类“Bootstrapper”，编辑如下：

 1 using Microsoft.Practices.Unity;
 2 using Prism.Regions;
 3 using Prism.Unity;
 4 using System.Windows;
 5 using System.Windows.Controls;
 6 using CustomRegions.Prism;
 7 using CustomRegions.Views;
 8 
 9 namespace CustomRegions
10 {
11     public class Bootstrapper:UnityBootstrapper
12     {
13         protected override DependencyObject CreateShell()
14         {
15             return Container.Resolve<MainWindow>();
16         }
17 
18         protected override void InitializeShell()
19         {
20             Application.Current.MainWindow.Show();
21         }
22 
23         protected override RegionAdapterMappings ConfigureRegionAdapterMappings()
24         {
25             RegionAdapterMappings mappings = base.ConfigureRegionAdapterMappings();
26             mappings.RegisterMapping(typeof(StackPanel), Container.Resolve<StackPanelRegionAdapter>());
27             return mappings;
28         }
29     }
30 }

　　4、创建文件夹Views，将MainWindow.xaml移动到此文件夹中。添加Prism文件夹，添加“StackPanelRegionAdapter.cs”类。

　　　　

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 using System.Windows;
 7 using System.Windows.Controls;
 8 using Prism.Regions;
 9 
10 namespace CustomRegions.Prism
11 {
12     public class StackPanelRegionAdapter:RegionAdapterBase<StackPanel>
13     {
14         public StackPanelRegionAdapter(IRegionBehaviorFactory regionBehaviorFactory)
15             : base(regionBehaviorFactory)
16         {
17 
18         }
19 
20         protected override void Adapt(IRegion region, StackPanel regionTarget)
21         {
22             region.Views.CollectionChanged += (s, e) =>
23             {
24                 if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add)
25                 {
26                     foreach (FrameworkElement element in e.NewItems)
27                     {
28                         regionTarget.Children.Add(element);
29                     }
30                 }
31 
32                 //handle remove
33             };
34         }
35 
36         protected override IRegion CreateRegion()
37         {
38             return new AllActiveRegion();
39         }
40     }
41 }
 1 <Window x:Class="CustomRegions.Views.MainWindow"
 2         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 3         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

 5         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
 6         xmlns:local="clr-namespace:CustomRegions.Views"
 7         xmlns:prism="http://prismlibrary.com/"
 8         mc:Ignorable="d"
 9         Title="Shell" Height="450" Width="800">
10     <Grid>
11         <ContentControl prism:RegionManager.RegionName="ContentRegion"></ContentControl>
12     </Grid>
13 </Window>
