我正在使用这种方式从串口读取:
public static void Main()
{
SerialPort mySerialPort = new SerialPort("COM1");
mySerialPort.BaudRate = 9600;
mySerialPort.Parity = Parity.None;
mySerialPort.StopBits = StopBits.One;
mySerialPort.DataBits = 8;
mySerialPort.Handshake = Handshake.None;
mySerialPort.DataReceived += new SerialDataReceivedEventHandler(DataReceivedHandler);
mySerialPort.Open();
Console.WriteLine("Press any key to continue...");
Console.WriteLine();
Console.ReadKey();
mySerialPort.Close();
}
private static void DataReceivedHandler(object sender, SerialDataReceivedEventArgs e)
{
SerialPort sp = (SerialPort)sender;
string indata = sp.ReadExisting();
Debug.Print("Data Received:");
Debug.Print(indata);
}
众所周知,这种 API 称为基于事件的异步模式 (EAP),我想使用 Async Await 方法编写上述代码。
PS:使用上面的代码有时我会得到错误的数据
在此先感谢
