|ZYCWPF| 我给ColorPicker添加了事件，但为什么没有办法执行呢

Question

        public static readonly RoutedEvent SelectColorCompletedEvent =
         EventManager.RegisterRoutedEvent("SelectColorCompleted",
          RoutingStrategy.Bubble, typeof(RoutedEventArgs), typeof(ColorPicker));
        public event RoutedEventHandler SelectColorCompleted
        {
            add
            {
                this.AddHandler(SelectColorCompletedEvent, value);
            }
            remove
            {
                this.RemoveHandler(SelectColorCompletedEvent, value);
            }
        }我给ColorPicker添加了这个颜色选定后的事件执行
然后我在ColorPicker的其他事法里面来执行这个事件上，
但以下代码提示格式有问题if(this.SelectColorCompleted!=null)
this.SelectColorCompleted.Invoke(null, null);
}正确写法为怎么写谢谢

Answer 1

this.RaiseEvent(new RoutedEventArgs(SelectColorCompletedEvent));
