一、使用prism框架
1.建立一個(gè)項(xiàng)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(jìn)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(huì)啟動(dòng)2個(gè)窗口
5.重新編譯后，點(diǎn)擊實(shí)現(xiàn)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(shí)現(xiàn)的內(nèi)容}} }注意：建立項(xiàng)目的時(shí)候不要包含.Prism，一開始我就進(jìn)坑了?
6. 界面隨便拖動(dòng)一個(gè)控件，點(diǎn)擊運(yùn)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(gè)?
2.進(jìn)行安裝
3.安裝完成，需要重啟vs2022，可以選擇建立一個(gè)空項(xiàng)目
選擇容器
4.項(xiàng)目文件預(yù)覽
使用模板這里已經(jīng)把需要修改的都修改完了。?
二、prism區(qū)域介紹
?1.首先進(jìn)行布局
業(yè)務(wù)，點(diǎn)擊按鈕，彈框?qū)?yīng)的區(qū)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(gè)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(chuàng)建命令，string用來接收參數(shù)，例如ViewApublic MainViewModel(IRegionManager regionManager)//這里點(diǎn)擊快速操作。拿界面定義的區(qū)域Content{OpenCommand = new DelegateCommand<string>(Open);this.regionManager = regionManager;//拿到這個(gè)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(jí)，不能少了
例如：
<Window x:Class="WPFPrism.Views.MainView">
不能漏寫Views文件夾的名字
因?yàn)镸VVM修改代碼的時(shí)候，不是順序常規(guī)性的，總是前面改了，再改后面，所以導(dǎo)致前面的代碼和成型的代碼差異很大。
總體代碼結(jié)構(gòu)：
?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(chuàng)建命令，string用來接收參數(shù)，例如ViewApublic MainViewModel(IRegionManager regionManager)//這里點(diǎn)擊快速操作。拿界面定義的區(qū)域Content{OpenCommand = new DelegateCommand<string>(Open);this.regionManager = regionManager;//拿到這個(gè)值}private void Open(string obj){regionManager.Regions["Content"].RequestNavigate(obj);//這里需要依賴注入的方式}}}MainView.xaml ? ?

<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 ?
