WinForms任务栏图标 - 单击事件不触发 [英] WinForms Taskbar Icon - Click Event not firing

问题描述

我创建了一个使用NotifyIcon类的 非表单 c＃程序。

I have created a non-form c# program that uses the NotifyIcon class.

文本 （单击以激活）当我悬停鼠标时显示。
所以我处理了一些事件。

The text "(Click to Activate)" shows up when I hover the mouse. So I am getting some events handled.

但是，点击事件不会触发，而且上下文菜单也不显示。

However, The "Click" event does not fire and the Context menu doesnt show up.

public class CTNotify
{
    static NotifyIcon CTicon = new NotifyIcon();
    static ContextMenu contextMenu = new ContextMenu();

    static void Main()
    {
        //Add a notify Icon
        CTicon.Icon = new Icon("CTicon.ico");
        CTicon.Text = "(Click to Activate)";
        CTicon.Visible = true;
        CTicon.Click += new System.EventHandler(CTicon_Click);

        //Create a context menu for the notify icon
        contextMenu.MenuItems.Add("E&xit");

        //Attach context menu to icon
        CTicon.ContextMenu = contextMenu;

        while (true) //Infinite Loop
        {
            Thread.Sleep(300); //wait 
        }
    }

    private static void CTicon_Click(object sender, System.EventArgs e)
    {
        MessageBox.Show("Clicked!");
    }
 }

推荐答案

Take查看 Shell_NotifyIcon（） API方法，实现NotifyIcon的方法。点击进入NOTIFYICONDATA结构。该结构的第二个成员是一个窗口句柄：

Take a look at the Shell_NotifyIcon() API method, the one that implements a NotifyIcon. Click through to the NOTIFYICONDATA structure. The second member of that structure is a window handle:

窗口的句柄，它接收与图标相关的
通知$通知区域中的b $ b

A handle to the window that receives notifications associated with an icon in the notification area

您没有窗口，因此无法接收通知。您必须将NotifyIcon放在表单上。并使用Application.Run（）来获取通知并激活事件处理程序。

You don't have a window and can therefore not receive notifications. You must put the NotifyIcon on a Form. And use Application.Run() to get the notifications and activate the event handlers.

通过粘贴此代码来隐藏表单：

Keep your form hidden by pasting this code:

    protected override void SetVisibleCore(bool value) {
        if (!this.IsHandleCreated) {
            this.CreateHandle();
            value = false;
        }
        base.SetVisibleCore(value);
    }
