Question

我正在尝试识别哪个BalloonTip（NotifyIcon）发送了BalloonTipClicked（以及已关闭和已显示）事件，因为我有几个不同的场景，可以显示气球，它们不是全部相同，也不会有相同的预期动作。

是否有人知道您是否可以识别发送Clicked / Closed / Shown事件的BalloonTip的任何？

Answer 1

这是一种解决方法，但您可以创建方法（或扩展方法）

public static void ShowBalloonAndUpdate(this NotifyIcon ni, int timeout, string title, string text, ToolTipIcon icon )
{
    ni.BalloonTipTitle = title;
    ni.BalloonTipText = text;
    ni.BalloonTipIcon = icon;
    ni.ShowBalloonTip(timeout);
}

使用该方法调用BalloonTip时，它将更新NotifyIcon的属性。

myNotifyIcon.ShowBalloonAndUpdate(1000, "Hello" "My Message", ToolTipIcon.Info);

然后可以在任何BalloonTip事件中读取这些属性。您可以根据其中一个属性（例如BalloonTitle）

决定做什么

private void myNotifyIcon_BalloonTipShown(Object sender, EventArgs e) 
{
    NotifyIcon ni = sender as NotifyIcon;
    if(ni != null)   
    {
        switch(ni.BalloonTitle)
        {
            case "Hello":
                  //Hello tooltip was shown
                  break;
            //...
        }
    }
}

这看起来确实很难破解。感谢@keyboardP的建议，因为它是一个可行的选择，但我最终创建了一个特殊的方法和枚举（因为当我得到答案或评论时SO没有给我发电子邮件......我需要检查我的首选项... ）：

internal static void ShowTip(Int32 timeout, String tipTitle, String tipText, ToolTipIcon tipIcon = ToolTipIcon.None, ShowTipAction tipAction = ShowTipAction.STA_Shown_WriteReg, String linkToOpen = "")
{
    if ((tipAction & ShowTipAction.STA_Nothing) == 0) // if STA_Nothing has not been passed
    {
        if ((tipAction & ShowTipAction.STA_Clicked_Nothing) == 0 && ((tipAction & ShowTipAction.STA_Clicked_OpenLink) > 0 || (tipAction & ShowTipAction.STA_Clicked_WriteReg) > 0))
            trayIcon.BalloonTipClicked += (s, e) => // if STA_Clicked_Nothing has not been passed and either STA_Clicked_OpenLink or STA_Clicked_WriteReg has been passed
            { // when this balloon tip is clicked
                if ((tipAction & ShowTipAction.STA_Clicked_OpenLink) > 0) // open passed link
                    MethodorProcessToLaunchSite(linktoOpen);
                if ((tipAction & ShowTipAction.STA_Clicked_WriteReg) > 0) // write notification indicator to registry
                    RegWriteMethod;
            };
        if ((tipAction & ShowTipAction.STA_Closed_Nothing) == 0 && (tipAction & ShowTipAction.STA_Closed_WriteReg) > 0) // if STA_Closed_Nothing has not been passed and STA_Closed_WriteReg has been passed
            trayIcon.BalloonTipClosed += (s, e) => { RegWriteMethod; }; // when this balloon tip is closed, write notification indicator to registry
        if ((tipAction & ShowTipAction.STA_Shown_Nothing) == 0 && (tipAction & ShowTipAction.STA_Shown_WriteReg) > 0) // if STA_Shown_Nothing has not been passed and STA_Shown_WriteReg has been passed
            trayIcon.BalloonTipShown += (s, e) => { RegWriteMethod; }; // when this balloon tip is shown, write notification indicator to registry
    }

    // Show the balloon tip
    trayIcon.ShowBalloonTip(timeout, tipTitle, tipText, tipIcon);
}

......和枚举：

[Flags]
internal enum ShowTipAction
{
    STA_Nothing = 1,
    STA_Clicked_Nothing = 2,
    STA_Clicked_OpenLink = 4,
    STA_Clicked_WriteReg = 8,
    STA_Closed_Nothing = 16,
    STA_Closed_WriteReg = 32,
    STA_Shown_Nothing = 64,
    STA_Shown_WriteReg = 128
}

在lambdas和enum之间，我可以根据自己的喜好进行扩展。我知道这不是最漂亮的解决方案，但它有效;非常好！
