使用c＃控制台应用程序的系统任务栏图标不会显示菜单 [英] System tray icon with c# Console Application won't show menu

问题描述

我有一个小的C＃（.NET 4.0）控制台应用程序，我希望用户能够通过右键单击系统任务栏图标显示菜单来进行交互。我可以毫无问题地向托盘添加一个图标，但是我无法使菜单出现。我正在使用以下代码：

I've got a small C# (.NET 4.0) Console Application that I'd like the user to be able to interact by showing a menu when they right-click the System Tray icon. I can add an icon to the Tray with no problems, but I just cannot get the menu to appear. I'm using the following code:

NotifyIcon trayIcon = new NotifyIcon();
trayIcon.Text = "TestApp";
trayIcon.Icon = new Icon(SystemIcons.Application, 40, 40);

ContextMenu trayMenu = new ContextMenu();

trayMenu.MenuItems.Add("Blah", item1_Click);
trayMenu.MenuItems.Add("Blah2", item1_Click);
trayMenu.MenuItems.Add("Blah3", item1_Click);

trayIcon.ContextMenu = trayMenu;
trayIcon.Visible = true;

...这会将图标放入托盘。但是，右键单击该图标不会执行任何操作。我尝试了 MenuItems.Add 的各种排列，但是没有任何东西会使菜单出现。我确定我缺少简单的东西-有什么想法吗？

... which puts the icon in the tray. However, right-clicking the icon does nothing. I've tried various permutations of MenuItems.Add, but nothing will make the menu appear. I'm sure I'm missing something simple - any ideas what?

推荐答案

在创建图标后尝试添加以下内容：

Try adding this after you create the icon:

Application.Run()

请注意，此方法将不会返回，因此调用后将无法执行任何操作。这意味着您将必须在单独的线程中完成所有其他工作。

Note that this method will not return, so you can't do anything after calling it. This means that you'll have to do all your other work in a separate thread.

发生的事情是，操作系统向您的应用程序发送了一条消息，告诉它托盘图标已被右键单击，但是任务栏图标代码从未看到它（因为这些消息由 Application.Run 处理），因此无法通过打开菜单进行响应。

What happens is that the OS sends your application a message telling it that the tray icon has been right-clicked, but the tray icon code never sees it (because these messages are processed by Application.Run) and so can't respond by opening the menu.
