c# - Mahapp ShowMessageAsync MvvM

Question

我使用 MVVM 模式创建了最简单的 WPF 项目。如何从我的 viewModel 调用 ShowMessageAsync？

 if (DisciplineText!="")
 {
     Disciplines.Add(new Discipline(){ChairID = SelectedChair.ChairID,SemesterID = SelectedSemester.SemesterID,Discipline1 = DisciplineText});
     Context.SaveChanges();
 }
 else
 {
     //  ShowMessageAsync????????
 }

Answer 1

MetroWindow metroWindow = Application.Current.MainWindow as MetroWindow;
metroWindow.MetroDialogOptions.ColorScheme = MetroDialogColorScheme.Accented; // set the theme
await MetroWindow.ShowMessageAsync("Title", "Message");

你需要使用:

using MahApps.Metro.Controls;
using MahApps.Metro.Controls.Dialogs;

希望对你有所帮助:)
