下面是我的代码,首先是我提出事件的地方,第二部分是我在另一个类中使用它的地方.它看起来很简单,但是日志显示即使事件被提升一次,事件也会在消耗此事件的类上触发20次.有任何想法吗？
IBSerialPort类：
public delegate void PacketReceivedHandler(object sender,PacketReceivedEventArgs e);
public event PacketReceivedHandler OnPacketReceived;
public class PacketReceivedEventArgs : EventArgs
{
public Packet PacketReceived { get; private set; }
public PacketReceivedEventArgs(Packet packet)
{
PacketReceived = packet;
}
}
// raise event
if (OnPacketReceived != null)
{
Log("This is only called ONCE!");
PacketReceivedEventArgs args = new PacketReceivedEventArgs(data);
OnPacketReceived(this,args);
}
使用IBSerialPort并使用其OnPacketReceived事件的类：
IBSerialPort ibSerialPort = null;
..
if (ibSerialPort == null)
{
Log("This is only called once");
ibSerialPort = IBSerialPort.Instance;
ibSerialPort.OnPacketReceived += ibSerialPort_OnPacketReceived;
}
void ibSerialPort_OnPacketReceived(object sender,IBSerialPort.PacketReceivedEventArgs args)
{
Log("This is called ~25 times!!!!");
}
