如何从 ResourceDictionary 类 (WPF) 导航到 xaml 页面

Question

I have a ResourceDictionary class as follows:

 using System.Windows.Navigation; using static myApp.filesXAML.Login; namespace myApp.Clases { partial class functionsMenu : ResourceDictionary { private void imageCloseMyApp(object sender, MouseButtonEventArgs e) { NavigationService.Navigate(new Uri("filesXAML/Login.xaml", UriKind.Relative)); } } }

The imageCloseMyApp function is invoked from an image by clicking on it and I wish to call another page.

And I get the following error before compiling the project:

Severity Code Description Project File Line Status deleted Error CS0120 An object reference is required for the field, method or property 'NavigationService.Navigate (Uri)' not static myApp H:\\pro\\Visual_Studio\\myApp\\myApp\\Classes\\ FunctionsMenu.cs 35 Active

I have searched the internet, and tried the following options:

 Login page = new Login(); page.NavigationService.Navigate(new Uri("filesXAML/Login.xaml",UriKind.RelativeOrAbsolute)); // or NavigationService nav = NavigationService.GetNavigationService(Application.Current.Windows[0].Parent); nav.Navigate(new Uri("filesXAML/Login.xaml", UriKind.Relative));

But none works.

Any suggestions or comments?

I have achieved it as follows:

 NavigationService nav = NavigationService.GetNavigationService((Grid)((Image)sender).Parent); nav.Navigate(new Uri("filesXAML/Login.xaml", UriKind.Relative));

I guide myself to understand the following thread:
