c# - 在 WPF 窗口中确定窗口关闭发件人

Question

我想在用户通过单击关闭按钮(红色 X 按钮)取消我的对话框时执行特定操作

而不是在表单因其他操作而关闭时。我如何确定是否

private void Window_Closing(object sender, CancelEventArgs e)

按钮引发事件？

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Height="60" Width="284" WindowStartupLocation="CenterScreen" 
    BorderBrush="#FFCCCCCC"
    BorderThickness="2"
    Background="#FFE0E0E0"
    WindowStyle="SingleBorderWindow" 
    ShowInTaskbar="False" ResizeMode="NoResize" Closing="Window_Closing">

Answer 1

    public MainWindow()
    {
        InitializeComponent();
        this.Closing+=new System.ComponentModel.CancelEventHandler(MainWindow_Closing);

    }
    private void MainWindow_Closing(object sender, EventArgs e)
    {
        MessageBox.Show("salman");

    }
