mouse click event fires before mouse double click event on notifyicon winforms c#

Question

Using my notify icon my function for mouse click and double click event are entirely different Mouse click event - will open a form Doouble click event - will open a folder

Mouse click event do its job but when fire the double click event, it still trigger the mouse click event by which my form still show on double click.

Actual result on double click: opens the folder and opens the form Expected result on double click: opens the folder

I already close the form on click but still show for a split second before hiding since the mouse click event is fired first before double click event.

  private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            //opens folder function

            //close widget on double click
            if (widgetForm != null)
                widgetForm.Close();
        }

Answer 1

This code I wrote for wpf also works with a slight change in winforms.

DispatcherTimer timer;
int clickCount = 0;
public MainWindow()
{
   InitializeComponent();
   timer = new DispatcherTimer();
   timer.Tick += Timer_Tick;
   timer.Interval = TimeSpan.FromMilliseconds(200);
}

private void MyButton_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
   clickCount++;
   timer.Start();
}
private void Timer_Tick(object sender, EventArgs e)
{
    timer.Stop();
    if (clickCount >= 2)
    {
       MessageBox.Show("doubleclick");
    }
    else
    {
       MessageBox.Show("click");
    }
    clickCount = 0;
}

for winforms:

System.Timers.Timer timer;
int clickCount = 0;
public Form1()
{
   InitializeComponent();
   timer = new System.Timers.Timer();
   timer.Elapsed += Timer_Elapsed;
   //SystemInformation.DoubleClickTime default is 500 Milliseconds
   timer.Interval = SystemInformation.DoubleClickTime;
   //or
   timer.Interval = 200;
}

private void myButton_MouseDown(object sender, MouseEventArgs e)
{
   clickCount++;
   timer.Start();
}

private void Timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    timer.Stop();
    if (clickCount >= 2)
    {
       MessageBox.Show("doubleclick");
    }
    else
    {
       MessageBox.Show("click");
    }
    clickCount = 0;       
}

With the code I mentioned in the wpf example, you can change SystemInformation.DoubleClickTime to your desired time
