wpf prism View Injection（视图注入）

1.新建wpf

2.添加prism.unity(v8.0)的引用

3 修改App.xaml

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

4 修改App.xaml.cs 

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

namespace ViewInjection
{
    /// <summary>
    /// App.xaml 的交互逻辑
    /// </summary>
    public partial class App : PrismApplication
    {
        protected override Window CreateShell()
        {
            return Container.Resolve<MainWindow>();
        }

        protected override void RegisterTypes(IContainerRegistry containerRegistry)
        {
            
        }
    }
}

5 添加Views文件夹，在其下面添加用户控件

<UserControl x:Class="ViewInjection.Views.ViewA"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:ViewInjection.Views"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
    <Grid>
        <TextBlock Text="ViewA" FontSize="36"/>
    </Grid>
</UserControl>

6 修改MainWindow.xaml

<Window x:Class="ViewInjection.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:ViewInjection"
        xmlns:prism="http://prismlibrary.com/"
        mc:Ignorable="d"
        Title="Shell" Height="450" Width="800">
    <DockPanel LastChildFill="True">
        <Button DockPanel.Dock="Top" Click="Button_Click" >Add View</Button>
        <ContentControl prism:RegionManager.RegionName="ContentRegion"/>
    </DockPanel>
</Window>

7 修改MainWindows.xaml.cs,给MainWindow构造函数添加依赖IUnityContaier和IRegionManager

using Prism.Regions;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using Unity;
using ViewInjection.Views;

namespace ViewInjection
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        IUnityContainer _container;
        IRegionManager _manager;
        public MainWindow(IUnityContainer container,IRegionManager manager)
        {
            InitializeComponent();
            this._container = container;
            this._manager = manager;
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            var view = _container.Resolve<ViewA>();
            IRegion region = _manager.Regions["ContentRegion"];
            region.Add(view);

        }
    }
}
