[Unity][FairyGUI]GButton点击传递参数_fairygui的click事件如何加参数

这是错误的写法

...
        btn.onClick.Add(btnClick);
        //btn.onClick.Set(btnClick);
...
    private void btnClick(EventContext context)
    {
        Debug.Log("btnClick  name:id:" + context.type+ "/data:" + context.data+ "/sender:" + context.sender);//没有报错显示结果//btnClick  name:id:onClick/data:FairyGUI.InputEvent/sender:FairyGUI.GButton
 
        //GButton item = (GButton)context.data;
        //Debug.Log("btnClick  item:" + item.id);//TargetException: Object of type 'FairyGUI.InputEvent' doesn't match target type 'FairyGUI.GO
        //context.sender.GObject
        //GObject item = (GObject)context as GObject;//报错
        //Debug.Log("btnClick  item1:" + item.id);
    }

...
btn.onClick.Add(() => {
            click(btn);
        });
