一、使用场景

在普遍的业务场景当中，必不可少的是页面切换，而Prism就可以使用Navigation功能来进行页面导航，在不同的场景当中会有各种用法，例如在切换页面验证、传递参数、返回上一页、返回下一页等功能。

二、导航的使用

2.1 注册显示区域（region）

这个在前面章节已做详细介绍不再赘述。

2.2 注册导航页面（View）

之前的介绍中我们一般是将一个View指定到一个region中。而现在我们需要将多个View注册到导航中。例如我们现在有两个子模块（ViewAModule和ViewBModule），我们分别注册导航界面：

    public class ViewAModule : IModule{public void OnInitialized(IContainerProvider containerProvider){}public void RegisterTypes(IContainerRegistry containerRegistry){containerRegistry.RegisterForNavigation(typeof(ViewA.Views.ViewA), "ViewA");}}

    public class ViewBModule : IModule{public void OnInitialized(IContainerProvider containerProvider){}public void RegisterTypes(IContainerRegistry containerRegistry){containerRegistry.RegisterForNavigation(typeof(ViewB.Views.ViewB), "ViewB");}}

注意这一段代码：

containerRegistry.RegisterForNavigation(typeof(ViewB.Views.ViewB), "ViewB");

这就代码就是注册导航页面的，其中第一个参数是View的类型，第二个参数是ViewName（可省略，则默认为View类型的类名）。当然，这句代码也可以在App类中的重写函数中实现。

        protected override void RegisterTypes(IContainerRegistry containerRegistry){containerRegistry.RegisterForNavigation(typeof(ViewA.Views.ViewA), "ViewA");containerRegistry.RegisterForNavigation(typeof(ViewB.Views.ViewB), "ViewB");}

然后我们在主界面上添加两个按钮用于导航：

    <Grid><Grid.RowDefinitions><RowDefinition Height="auto" /><RowDefinition /></Grid.RowDefinitions><StackPanelGrid.Row="0"Margin="10"Orientation="Horizontal"><ButtonWidth="40"Height="30"Margin="40,0,40,0"Command="{Binding NavigationCmd}"CommandParameter="ViewA"Content="ViewA" /><ButtonWidth="40"Height="30"Margin="40,0,40,0"Command="{Binding NavigationCmd}"CommandParameter="ViewB"Content="ViewB" /></StackPanel><ContentControl Grid.Row="1" prism:RegionManager.RegionName="ContentRegion" /></Grid>

在MainViewModel中我们进行了一些数据的绑定：

    public class MainWindowViewModel : BindableBase{public DelegateCommand<string> NavigationCmd { get; private set; }private IRegionManager region;public MainWindowViewModel(IRegionManager regionManager){this.region = regionManager;NavigationCmd = new DelegateCommand<string>(Navigation);}private void Navigation(string page){region.RequestNavigate("ContentRegion", page);}}

注意这一段代码：

region.RequestNavigate("ContentRegion", page);

第一个参数是RegionName，第二个参数是我们前面注册的ViewName。其实它还有很多重载函数，还有另外两个参数Action navigationCallback和NavigationParameters navigationParameters。

2.3 导航完成后的回调

        private void Navigation(string page){region.RequestNavigate("ContentRegion", page,NavigationCallback);}private void NavigationCallback(NavigationResult result){Console.WriteLine(result.Context.Uri);Console.WriteLine(result.Error.Message);Console.WriteLine(result.Result.Value);}

请求导航完成的回调函数。

2.4 请求导航时的参数

        private void Navigation(string page){NavigationParameters parameters= new NavigationParameters("param1");region.RequestNavigate("ContentRegion", page,NavigationCallback, parameters);}

这个参数有什么用，怎么用，我们在后面详说。

2.5 INavigationAware

我们导航切换界面到底是一个什么过程呢？这样我们需要了解INavigationAware接口。该接口有三个方法需要实现。

        public void OnNavigatedTo(NavigationContext navigationContext){throw new NotImplementedException();}public bool IsNavigationTarget(NavigationContext navigationContext){throw new NotImplementedException();}public void OnNavigatedFrom(NavigationContext navigationContext){throw new NotImplementedException();}

OnNavigatedTo: 导航到当前页面前, 此处可以传递过来的参数以及是否允许导航等动作的控制
IsNavigationTarget: 是否创建新示例。为true的时候表示不创建新示例，页面还是之前的；如果为false，则创建新的页面。
OnNavigatedFrom: 导航离开当前页面前。

传递参数示例：

  var parameters = new NavigationParameters();parameters.Add("person", person);

        public void OnNavigatedTo(NavigationContext navigationContext){var person = navigationContext.Parameters["person"] as Person;if (person != null)SelectedPerson = person;}

注意，这个接口应该由ViewModel来继承。

所以一个完整的导航请求的过程如下：

OnNavigatedTo

NavigateComplete

2.6 IConfirmNavigationRequest

该接口继承自INavigationAware，所以，它多了一个功能：允许用户针对导航请求进行拦截。同时也需要多实现一个方法：

        public void ConfirmNavigationRequest(NavigationContext navigationContext, Action<bool> continuationCallback){throw new NotImplementedException();}

    public void ConfirmNavigationRequest(NavigationContext navigationContext, Action<bool> continuationCallback){bool result = true;if (MessageBox.Show("Do you to navigate?", "Navigate?", MessageBoxButton.YesNo) == MessageBoxResult.No)result = false;//true则同意 false则拒绝continuationCallback(result);}

所以这个接口的执行流程为：

2.7 IRegionNavigationJournal

导航日志，其实就是对导航系统的一个管理功能，理论上来说，我们应该知道我们上一步导航的位置、以及下一步导航的位置，包括我们导航的历史记录。以便于我们使用导航对应用程序可以灵活的控制。

IRegionNavigationJournal接口有如下功能：

GoBack() : 返回上一页
CanGoBack : 是否可以返回上一页
GoForward(): 返回后一页
CanGoForward : 是否可以返回后一页

        IRegionNavigationJournal _journal;public void OnNavigatedTo(NavigationContext navigationContext){_journal = navigationContext.NavigationService.Journal;}

我们可以在OnNavigatedTo函数中得到IRegionNavigationJournal的实现，然后就可以使用相应的方法。

三、InvokeCommandAction

直接由控件的事件触发，然后转化为Command。

   xmlns:i="http://schemas.microsoft.com/xaml/behaviors"<ListBox x:Name="_listOfPeople" ItemsSource="{Binding People}"><i:Interaction.Triggers><i:EventTrigger EventName="SelectionChanged"><prism:InvokeCommandAction Command="{Binding PersonSelectedCommand}" CommandParameter="{Binding SelectedItem, ElementName=_listOfPeople}" /></i:EventTrigger></i:Interaction.Triggers></ListBox>

上面的一种方式是传送一个其他的参数给命令。是否可以直接将事件参数传递给命令呢？

        xmlns:i="http://schemas.microsoft.com/xaml/behaviors"<ListBox Grid.Row="1" Margin="5" ItemsSource="{Binding Items}" SelectionMode="Single"><i:Interaction.Triggers><!-- This event trigger will execute the action when the corresponding event is raised by the ListBox. --><i:EventTrigger EventName="SelectionChanged"><!-- This action will invoke the selected command in the view model and pass the parameters of the event to it. --><prism:InvokeCommandAction Command="{Binding SelectedCommand}" TriggerParameterPath="AddedItems" /></i:EventTrigger></i:Interaction.Triggers></ListBox>

 public IList<string> Items { get; private set; }public DelegateCommand<object[]> SelectedCommand { get; private set; }public MainWindowViewModel(){Items = new List<string>();Items.Add("Item1");Items.Add("Item2");Items.Add("Item3");Items.Add("Item4");Items.Add("Item5");// This command will be executed when the selection of the ListBox in the view changes.SelectedCommand = new DelegateCommand<object[]>(OnItemSelected);}private void OnItemSelected(object[] selectedItems){if (selectedItems != null && selectedItems.Count() > 0){SelectedItemText = selectedItems.FirstOrDefault().ToString();}}

代码中Command的参数是object[]类型，我也不知道为什么。。。。请大佬告知！！！
