具有视图模型类型的 WPF Prism RegisterTypeForNavigation [英] WPF Prism RegisterTypeForNavigation with viewmodel type

问题描述

在 WPF + Prism 中，如何使用视图模型类型导航到强类型对象:

In WPF + Prism, how can I navigate to a strongly type object using view-model type:

_navigationService.NavigateAsync<MainPageviewModel>();

为了让它起作用，我想我需要这样的东西:

For this to work I suppose I'd need something like this:

Container.RegisterTypeForNavigation<MainPage, MainPageViewModel>();

推荐答案

你只需要这个

 Container.RegisterTypeForNavigation<MainPage>();

为了能够导航，您可能希望 viewmodellocator(在 xaml 上)为您创建视图模型.

to be able to navigate, then you probably want viewmodellocator (on the xaml) to create you the viewmodel.

这是你发送参数的方式

var navigationParameters = new NavigationParameters();

navigationParameters.Add("ParameterKey","TheParameter")

RegionManager.RequestNavigate("YouRegionName", new Uri(nameOf(MainPage),   UriKind.Relative), navigationParameters);

当你收到它们时，你必须检查 OnNavigatedTo 方法中的 navigationContext 并通过密钥访问它们.

when you receive them, you have to check the navigationContext in OnNavigatedTo method and access them by the key.
