WPF MVVM实践 -- 创建Prism应用程序

1. 创建PrismDemo项目

源码: https://github.com/liugang198409/MVVMDemo/tree/master/PrismDemo

1.1 环境

Visual Studio 2019

.NET Framework 4.8.1

1.2 创建

 2. NuGet安装依赖包

Prism.DryIoc

3. 修改App.xmal.cs的App类继承PrismApplication

using Prism.DryIoc;

namespace PrismDemo
{
    /// <summary>
    /// App.xaml 的交互逻辑
    /// </summary>
    public partial class App : PrismApplication
    {
       
    }
}

4. App.xmal代码修改

4.1 删除startUrl

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

4.2 引入prismLibary

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

4.3 修改<Application>为<prism:PrismApplication>

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

5.实现App.xmal.cs中继承类中的方法

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 PrismDemo
{
    /// <summary>
    /// App.xaml 的交互逻辑
    /// </summary>
    public partial class App : PrismApplication
    {
        protected override Window CreateShell()
        {
            //这里代表启动的view是MainWindow
            return Container.Resolve<MainWindow>();
        }

        protected override void RegisterTypes(IContainerRegistry containerRegistry)
        {
            //注册类 这个Demo这里空着 不需要填写
        }
    }
}

6. MainWindow.xmal中添加一些展示

<Window x:Class="PrismDemo.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:PrismDemo"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <TextBlock Text="Hello Prism!" FontSize="40" FontWeight="Bold" VerticalAlignment="Center" HorizontalAlignment="Center"/>
    </Grid>
</Window>

7. 启动项目
