[問題] 串列埠的委派接收要怎介面化

[chuinzong (阿榮)]

各位好:

        目前可以執行的程式Serial Port的接收端程式

        由於現在想要在介面中添加SerialDataReceivedEventHandler，
以方便後面做單元測試(就是要開介面)。
// 程式碼To Do部分

        想詢問各位高手，介面開啟後
event SerialDataReceivedEventHandler PortDataReceived

要找尋什麼資料，現在用委派的Function要怎麼轉介面化?目前卡關在這邊。

    public interface ISerialPort
    {
        void Open();

        void Close();

        void WriteLine(byte[] ByteData);
        // To Do
        // event SerialDataReceivedEventHandler PortDataReceived;

        bool CheckOpenStaus();
    }

    public class DevicePort : ISerialPort
    {
        private SerialPort _serialPort;
        private Queue<byte> _dataReceive;

        public DevicePort()
        {
            _dataReceive = new Queue<byte>();

            _serialPort = new SerialPort($"COM4", 19200);
            _serialPort.DataReceived += new
SerialDataReceivedEventHandler(PortDataReceived);
        }

        public void Open()
        {
            _serialPort.Open();
        }

        public void Close()
        {
            _serialPort.Close();
        }

        public void WriteLine(byte[] ByteData)
        {
            _serialPort.Write(ByteData, 0, ByteData.Length);
            _dataReceive.Clear();
        }

        private void PortDataReceived(object sender,
SerialDataReceivedEventArgs e)
        {
            byte[] buffer = new byte[4];
            int length = (sender as SerialPort).Read(buffer, 0,
buffer.Length);

            foreach (byte i in buffer)
                _dataReceive.Enqueue(i);
        }

        public bool CheckOpenStaus()
        {
            return _serialPort.IsOpen;
        }
    }

以上
謝謝

推 Litfal: 介面一樣宣告成event
→ Litfal: 然後實作event把資料丟出去
