我有一个 vb.net 程序，它调用了一个.exe Process.start()关于此.exe的简短摘要：它从Web服务器下载文件，并在下载开始时发送一些Windows通知。如果我只是启动我的"LiveUpdate.exe"文件，这个算法工作正常。
这是我在 vb.net 代码中的调用：
Process.Start(location & "LiveUpdate.exe", "-f "settings.ini")
这是我的 c# 通知方法
public void Popup(string title, string description, Icon systemIcon, ToolTipIcon icon = ToolTipIcon.Info)
{
var notification = new NotifyIcon()
{
Visible = true,
Icon = systemIcon, //SystemIcons.Information,
BalloonTipIcon = icon,
BalloonTipTitle = title,
BalloonTipText = description
};
Task.Run(() => OpenAndCloseNotification(notification, 2));
}
public void OpenAndCloseNotification(NotifyIcon notification, int secconds)
{
var milisecconds = secconds * 1000;
notification.ShowBalloonTip(milisecconds);
Thread.Sleep(milisecconds);
notification.Dispose();
}
说 vb.net 不允许弹出 Windows - 通知？如果您需要，我会附加更多代码，提前感谢您。
这就是它的外观，您可以更改背景图像并删除透明胶片。如果不这样做，请选择具有纯背景的背景，以便将该颜色设置为透明，并且仅保留中心图像的形状。

自 windows10 以来，我在 Windows 通知方面也遇到了许多问题。我不知道这取决于什么，但有时有效，而其他人则不行。
您是否尝试直接在 CLIC 的按钮事件上显示通知？至少这样你会检查它是否有效。
无论如何，我最后要做的就是创建自己的通知，并在规定的时间内在桌子的角落显示一个表单。
如果你对这个解决方案感兴趣，我会告诉你代码
