C＃关闭到系统托盘（如MSN信使） [英] C# close to tray (like msn messenger)

问题描述

我有一个C＃.net应用程序。所以，我创建了一个在盘坐在一个NotifyIcon的。我想做的是当用户点击窗体上的X按钮，我希望它关闭托盘。他们应该只能够通过使用托盘图标的上下文菜单，退出程序。

I have a c# .net app. So I created a notifyIcon that sits in the tray. What I want to do is when the user hits the "x" button on the form, I want it to close to the tray. They should only be able to exit program by using the context menu in the tray icon.

所以我所做的就是，在表单关闭事件，我检查是否形式是可见的。如果它的可见的，我把它设置为不可见，并设置showInTaskbar为假（模拟最小化到托盘）如果表单是不可见已经，那么他们很可能从托盘关闭它，所以我将退出在这种情况下程序。

So what I did was, on the form close event, I check whether the form is visible. If its visible, i set it to invisible and set showInTaskbar to false (simulating minimize to tray) If the form is invisible already, then they are probably closing it from the tray, so I will exit the program in that case.

不过，我的问题是，如果窗口是可见的，但他们右键单击任务栏图标的上下文菜单和命中退出，我需要退出程序，而不是最小化。

However, the problem I have is that if the window is visible, but they right click on the context menu of the tray icon and hit exit, I need to exit the program and not minimize.

我该如何解决这个问题。

How do I solve this problem?

推荐答案

试试这个？

bool _closingFromMenu;

void NOTIFYICON_EXIT_MENU_HANDLER(object sender, EventArgs e)
{
    _closingFromMenu = true;
    Close();
}

//form closing handler
FormClosing +=(a,b) =>{
    if(_closingFromMenu){
        Close();
    }
    else{
        e.Cancel = true;
        //do minimize stuff;
    }
}

如果你只有一种形式，你可以调用 Application.Exit（）; 在上下文菜单项处理程序

or if you have only one form you can call Application.Exit(); in context menu item handler
