prism wpf 入门

1、安装

NgGet 中输入 prism，在列表中选择 Prism.Unity ，版本选择8.1.97

2.改 App.xaml 文件

先引入命名空间

xmlns:p="http://prismlibrary.com/"

再改成这样

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

生成一下项目，这个很重要

左再左边的【实现抽象类】

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 Cjh.PrismWpf
{
    /// <summary>
    /// App.xaml 的交互逻辑
    /// </summary>
    public partial class App : PrismApplication
    {
        protected override Window CreateShell()
        {
            throw new NotImplementedException();
        }

        protected override void RegisterTypes(IContainerRegistry containerRegistry)
        {
            throw new NotImplementedException();
        }
    }
}

修改

/// <summary>
/// App.xaml 的交互逻辑
/// </summary>
public partial class App : PrismApplication
{
    /// <summary>
    /// 提供主窗口的对象
    /// </summary>
    /// <returns></returns>
    /// <exception cref="NotImplementedException"></exception>
    protected override Window CreateShell()
    {
        return new MainWindow() { Title = "PrismMainWindow" };
    }

    /// <summary>
    /// 业务中所有需要注入的对象，在这个方法里注册
    /// </summary>
    /// <param name="containerRegistry"></param>
    /// <exception cref="NotImplementedException"></exception>
    protected override void RegisterTypes(IContainerRegistry containerRegistry)
    {
        
    }
}

启动程序测试一下

如果会出现两个窗口，可能是APP.xaml文件里的问题

可以直接删除

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