一、使用prism框架

1.建立一個項目，使用.net5.0框架

?2.在nuget中輸入prism，然后選擇prism.DryIoc安裝

3. 打開App.xaml.cs文件，繼承PrismApplication

using Prism.DryIoc; using System; using System.Collections.Generic; using System.Configuration; using System.Data; using System.Linq; using System.Threading.Tasks; using System.Windows;namespace WPFPrism {/// <summary>/// Interaction logic for App.xaml/// </summary>public partial class App : PrismApplication{} }

4.打開App.xaml文件，進行引用prism和修改

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

這里把?StartupUri="MainWindow.xaml"刪除，否則會啟動2個窗口

5.重新編譯后，點擊實現抽象類

using Prism.DryIoc; using Prism.Ioc; using System; using System.Collections.Generic; using System.Configuration; using System.Data; using System.Linq; using System.Threading.Tasks; using System.Windows;namespace WPFPrism {/// <summary>/// Interaction logic for App.xaml/// </summary>public partial class App : PrismApplication{protected override Window CreateShell(){//通過容器去拿Windowreturn Container.Resolve<MainWindow>();}protected override void RegisterTypes(IContainerRegistry containerRegistry){//依賴注入的功能，增加依賴注入要實現的內容}} }

注意：建立項目的時候不要包含.Prism，一開始我就進坑了?

6. 界面隨便拖動一個控件，點擊運行，效果

拓展：

使用模板建立速度更加的快。

這里是vs2022

1.在拓展中搜素prism?

下載第一個?

2.進行安裝

3.安裝完成，需要重啟vs2022，可以選擇建立一個空項目

選擇容器

4.項目文件預覽

使用模板這里已經把需要修改的都修改完了。?

二、prism區域介紹

?1.首先進行布局

業務，點擊按鈕，彈框對應的區域窗體

<Window x:Class="WPFPrism.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:WPFPrism"mc:Ignorable="d"Title="MainWindow" Height="450" Width="800"><Grid><Grid.RowDefinitions><RowDefinition Height="auto"/><RowDefinition /></Grid.RowDefinitions><StackPanel Orientation="Horizontal" ><Button Content="打開模塊A" Margin="5"/><Button Content="打開模塊B" Margin="5"/><Button Content="打開模塊C" Margin="5"/></StackPanel><ContentControl Grid.Row="1" /></Grid> </Window>

2.建立3個窗體

<UserControl x:Class="WPFPrism.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:WPFPrism.Views"mc:Ignorable="d" d:DesignHeight="450" d:DesignWidth="800"><Grid><TextBlock Text="我是A" FontSize="50"/></Grid> </UserControl>

A，B，C窗體代碼以此類推?

3. 建立MainViewModle類

using Prism.Commands; using Prism.Mvvm; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;namespace WPFPrism.ViewModels {public class MainViewModle : BindableBase{public DelegateCommand<string> OpenCommand { get; set; }public MainViewModle(){OpenCommand = new DelegateCommand<string>(Open);}private void Open(string obj){throw new NotImplementedException();}}}

4.在主界面增加RegionManager

<ContentControl Grid.Row="1" prism:RegionManager.RegionName="Content" />

5.修改MainViewModle類

using Prism.Commands; using Prism.Mvvm; using Prism.Regions; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using WPFPrism.Views;namespace WPFPrism.ViewModels {public class MainViewModel : BindableBase{private readonly IRegionManager regionManager;public DelegateCommand<string> OpenCommand { get; set; }//創建命令，string用來接收參數，例如ViewApublic MainViewModel(IRegionManager regionManager)//這里點擊快速操作。拿界面定義的區域Content{OpenCommand = new DelegateCommand<string>(Open);this.regionManager = regionManager;//拿到這個值}private void Open(string obj){regionManager.Regions["Content"].RequestNavigate(obj);//這里需要依賴注入的方式}}}

注意：

文件夾下面的的層級，不能少了

例如：

<Window x:Class="WPFPrism.Views.MainView">

不能漏寫Views文件夾的名字

因為MVVM修改代碼的時候，不是順序常規性的，總是前面改了，再改后面，所以導致前面的代碼和成型的代碼差異很大。

總體代碼結構：

?MainViewModel.cs

using Prism.Commands; using Prism.Mvvm; using Prism.Regions; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using WPFPrism.Views;namespace WPFPrism.ViewModels {public class MainViewModel : BindableBase{private readonly IRegionManager regionManager;public DelegateCommand<string> OpenCommand { get; set; }//創建命令，string用來接收參數，例如ViewApublic MainViewModel(IRegionManager regionManager)//這里點擊快速操作。拿界面定義的區域Content{OpenCommand = new DelegateCommand<string>(Open);this.regionManager = regionManager;//拿到這個值}private void Open(string obj){regionManager.Regions["Content"].RequestNavigate(obj);//這里需要依賴注入的方式}}}

MainView.xaml ? ?

<Window x:Class="WPFPrism.Views.MainView"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:prism="http://prismlibrary.com/"prism:ViewModelLocator.AutoWireViewModel="True"xmlns:local="clr-namespace:WPFPrism"mc:Ignorable="d"Title="MainView" Height="450" Width="800"><!--自動關聯AutoWireViewModel--><Grid><Grid.RowDefinitions><RowDefinition Height="auto"/><RowDefinition /></Grid.RowDefinitions><StackPanel Orientation="Horizontal" ><Button Content="打開模塊A" Margin="5" Command="{Binding OpenCommand}" CommandParameter="ViewA"/><Button Content="打開模塊B" Margin="5" Command="{Binding OpenCommand}" CommandParameter="ViewB"/><Button Content="打開模塊C" Margin="5" Command="{Binding OpenCommand}" CommandParameter="ViewC"/></StackPanel><ContentControl Grid.Row="1" prism:RegionManager.RegionName="Content" /></Grid> </Window>

ViewA.xaml? ? ? ? ? ? ? ? ? ? ?B C同理

<UserControl x:Class="WPFPrism.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:WPFPrism.Views"mc:Ignorable="d" d:DesignHeight="450" d:DesignWidth="800" Background="Red"><Grid><TextBlock Text="我是A" FontSize="50"/></Grid> </UserControl>

App.xaml ?

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

App.xaml.cs?

using Prism.DryIoc; using Prism.Ioc; using System; using System.Collections.Generic; using System.Configuration; using System.Data; using System.Linq; using System.Threading.Tasks; using System.Windows; using WPFPrism.Views;namespace WPFPrism {/// <summary>/// Interaction logic for App.xaml/// </summary>public partial class App : PrismApplication{protected override Window CreateShell(){//通過容器去拿MainView,也是啟動的地方return Container.Resolve<MainView>();}protected override void RegisterTypes(IContainerRegistry containerRegistry){//依賴注入的功能，增加依賴注入要實現的內容containerRegistry.RegisterForNavigation<ViewA>(); //containerRegistry.RegisterForNavigation<ViewA>("ViewA的具體名字")自定義，可以這樣寫;containerRegistry.RegisterForNavigation<ViewB>();containerRegistry.RegisterForNavigation<ViewC>();}} }
