Application.Current.Shutdown() 不会杀死我的应用程序 [英] Application.Current.Shutdown() is not killing my application

问题描述

我刚刚启动了一个新的 C#/WPF 应用程序，并且正在使用 WPF Contrib 项目 中的 NotifyIcon.我可以启动程序，将退出"菜单项添加到 NotifyIcon 的 ContextMenu，并将该项链接到一个只运行 Application.Current.Shutdown() 的方法.

这会关闭主窗口和 NotifyIcon，但有些东西继续运行 - 从 VS 运行，它不会离开调试模式.什么还在运行?或者我如何检查?

编辑

我刚刚尝试添加一个调用 Application.Current.Shutdown() 的按钮，该按钮可以正确退出.只有当我从 NotifyIcon 调用时才会出现问题.为什么会这样?

为了澄清，我有以下 XAML:

<网格><av:NotifyIcon Icon="/icon/path"文本="虚拟机管理器"名称="notifyIcon"><FrameworkElement.ContextMenu><上下文菜单><MenuItem Header="Exit" Click="MenuItemExit_Click"/></ContextMenu></FrameworkElement.ContextMenu></av:NotifyIcon><Button Content="Button" Click="button1_Click"/></网格>

button1_Click 和 MenuItemExit_Click 是相同的，但前者成功退出应用程序，后者没有.

进一步的实验:即使我将 Application.Current.Shutdown() 移动到另一个方法中并改为调用它，添加一个间接层，按钮仍然有效而图标没有.

找到解决方案了吗?

刚刚找到这个话题，他的解决方案在这里确实有效.我不完全明白发生了什么，所以如果有人愿意解释，我将不胜感激.

解决方案

你可以试试 Environment.Exit(0); 它会用给定的退出代码杀死进程.退出代码 0 表示应用程序成功终止.它可能更粗鲁"或未完成"，但也许这就是您要找的.

I've just started a new C#/WPF application and am using the NotifyIcon from the WPF Contrib project. I can start the program, add an "Exit" MenuItem to the NotifyIcon's ContextMenu, and link that item to a method that simply runs Application.Current.Shutdown().

This closes the main window and the NotifyIcon, but something continues to run - running from VS, it does not leave debug mode. What is still running? Or how can I check?

EDIT

I've just tried adding a button that calls Application.Current.Shutdown(), and that exits properly. It's only when called from the NotifyIcon that I have a problem. Why would this be?

To clarify, I have the following XAML:

<Window x:Class="VirtualBoxManager.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:av="http://schemas.codeplex.com/wpfcontrib/xaml/presentation"
    Title="VirtualBox Manager" Height="350" Width="525"
    ShowInTaskbar="False" WindowStyle="None">
<Grid>
    <av:NotifyIcon Icon="/icon/path"
                   Text="Virtual Machine Manager"
                   Name="notifyIcon">
        <FrameworkElement.ContextMenu>
            <ContextMenu>
                <MenuItem Header="Exit" Click="MenuItemExit_Click" />
            </ContextMenu>
        </FrameworkElement.ContextMenu>
    </av:NotifyIcon>
    <Button Content="Button" Click="button1_Click" />
</Grid>

Both button1_Click and MenuItemExit_Click are identical, but the former successfully exits the app and the latter does not.

Further experimentation: even if I move Application.Current.Shutdown() into another method and call that instead, adding a layer of indirection, still the button works and the icon doesn't.

Solution found?

Just found this thread, who's solution does work here. I don't totally understand what's happening, so if anybody cares to explain I'd appreciate it.

解决方案

You coult try Environment.Exit(0); It kills the process with the given exit code. Exit code 0 states the application terminated successfully. It might be more 'rude' or 'not-done' but perhaps this is what you are looking for.
