You are not trying to create an event. At best, you are trying to add a handle to the invocation list of existing event instance. But this would be += operator which you did not even show. You need to explain what you are really trying to achieve, exactly, and what is the problem.
Better first read how delegates and events work in a standard MSDN reference and manual.

Double click event. you can change the interval time.

C#

piCanv.PreviewMouseLeftButtonUp += new  MouseButtonEventHandler(Canvas_PreviewMouseLeftButtonUp);
int priviewTimestamp = -1;
const int iDoubleClickInterval = 500;
private void Canvas_PreviewMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
    if (priviewTimestamp > 0)
    {
        if (e.Timestamp - priviewTimestamp < iDoubleClickInterval)
        {
            //this is the double click event
            //raise the double click event here or handle it here
        }
        priviewTimestamp = e.Timestamp;
    }
    else
        priviewTimestamp = e.Timestamp;
}
