c# - 接口(interface)事件的实际使用

Question

<分区>

Answer 1

我使用事件在串行端口接收到数据时发出信号。

这是我的界面。

public interface ISerialPortWatcher
{
    event EventHandler<ReceivedDataEventArgs> ReceivedData;
    event EventHandler StartedListening;
    event EventHandler StoppedListening;

    SerialPortSettings PortOptions { set; }

    bool Listening { get; set; }
    void Stop();
    void Start();
}

public class ReceivedDataEventArgs : EventArgs
{
    public ReceivedDataEventArgs(string data)
    {
        Data = data;
    }
    public string Data { get; private set; }
}
