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>
