我正在开发一个wpf mvvm应用程序与笔记。面对这样一个事实，我无法在viewModel中处理窗口关闭事件。我发现了类似的问题，但答案使用Mvvm，这是我想要避免的。我可以这样处理：

FindNoteWindow.xaml

<Window x:Class="NotesARK6.View.FindNoteWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    DataContext="{Binding Path=FindNoteWindowViewModel, Source={StaticResource ViewModelLocator}}"
    mc:Ignorable="d"
    Closing="Window_Closing"
    Title="FindNoteWindow" Height="250" Width="400">

FindNoteWindow.xaml.cs

public partial class FindNoteWindow : Window
    public FindNoteWindow()
        InitializeComponent();
    private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
        // code
}

但这不是我需要的。我想像这样处理viewModel中的关闭事件：

FindNoteWindow.xaml

<Window x:Class="NotesARK6.View.FindNoteWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    DataContext="{Binding Path=FindNoteWindowViewModel, Source={StaticResource ViewModelLocator}}"
    mc:Ignorable="d"
    Closing="{Binding Window_Closing}"
    Title="FindNoteWindow" Height="250" Width="400">

FindNoteWindowViewModel.cs

    public void Window_Closing(object sender, CancelEventArgs e)
