标题[问题] 串列埠的委派接收要怎介面化
时间Tue Jun 9 18:11:09 2020
各位好:
目前可以执行的程式Serial Port的接收端程式
由於现在想要在介面中添加SerialDataReceivedEventHandler，
以方便後面做单元测试(就是要开介面)。
// 程式码To Do部分
想询问各位高手，介面开启後
event SerialDataReceivedEventHandler PortDataReceived
要找寻什麽资料，现在用委派的Function要怎麽转介面化?目前卡关在这边。
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
谢谢

1F：推 Litfal: 介面一样宣告成event 06/15 20:35
2F：→ Litfal: 然後实作event把资料丢出去 06/15 20:37
4F：→ Litfal: e-reference/keywords/event 06/15 20:37
