事件发送

1、定义
public event EventHandler<BoatChanged> BoatChangedEvent; //BoatChanged为类，可传递参数
public event EventHandler DataChanged; //无参数传递
2、发送
if (this.BoatChangedEvent != null) { this.BoatChangedEvent(null, new BoatChanged(this.Name)); }
if (this.DataChanged != null) { this.DataChanged(this, EventArgs.Empty); }
3、类定义

            this.Name= name;
        }

        public DateTime TimeStamp { get; }

        public string Name{ get; private set; }
