Navigation区域导航_registerfornavigation

Navigation区域导航

功能实现

这里以实现按钮打开A和打开B为例

首先创建ViewA和ViewB的页面

在App.xaml.cs中实现对页面的注册

 protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
    containerRegistry.RegisterForNavigation<ViewA>("PageA");
    containerRegistry.RegisterForNavigation<ViewB>();
}

在MainWindowViewModel中实现对区域内容的设置。以打开A为例，创建按钮，然后实现打开A的函数功能。

using Prism.Commands;
using Prism.Mvvm;
using Prism.Regions;
using System;

namespace BlankCoreApp1.ViewModels
{
    public class MainWindowViewModel : BindableBase
    {
        private readonly IRegionManager regionManager;

        public DelegateCommand OpenACommand { get; private set; }

        public MainWindowViewModel(IRegionManager regionManager)
        {
            OpenACommand = new DelegateCommand(OpenA);
            this.regionManager = regionManager;
        }

        private void OpenA()
        {
            // 设置区域内容为PageA的内容
            regionManager.RequestNavigate("ContentRegion", "PageA", param);
