嗨，我想在单击按钮时显示确认窗口。我正在尝试使用 MVVM 设计模式进行开发，我已经实现了，但我不认为在 viewModel 中调用视图
是正确的方法。我已经附上了代码，请检查它是否正确

<Window x:Class="MessegeBox_Demo_2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
        <Grid>
            <Button Content="Ckick ME" HorizontalAlignment="Left" 
                    Command="{Binding GetMessegeboxCommand}"
                    Margin="200,131,0,0" VerticalAlignment="Top" Width="75"/>

        </Grid>
    </Window>

public class MainWindowViewModel : ViewModelBaseClass
{
   private ICommand _getMessegeboxCommand;
   public ICommand GetMessegeboxCommand
   {
      get
      {
          return _getMessegeboxCommand ?? (_getMessegeboxCommand = new MessegeBox_Demo_2.Command.realyCommand(() => ShowUsercontrol(), true));
      }
   }
   private void ShowUsercontrol()
   {
      MessegeBox_Demo_2.View.Window1 mbox = new View.Window1();
      mbox.ShowDialog();
   }
}
