C#串口类封装 SuperSerialPort

C#串口类封装 SuperSerialPort

基于SerialPort类做了简单的封装方便调用

代码

	/// <summary>
    /// SuperSerialPort
  	/// </summary>
	public class SuperSerialPort
    {

        private SerialPort CommPort = new SerialPort();

        public SuperSerialPort()
        {
            CommPort.DataReceived += serialport_DataReceived;
        }

        private StringBuilder SerialDataReceived = new StringBuilder();

        private void serialport_DataReceived(object sender, SerialDataReceivedEventArgs e)
        {
            //读取数据
            int length = CommPort.BytesToRead;
            byte[] buffers = new byte[length];
            CommPort.Read(buffers, 0, length);

            //调用委托事件
            DataReceived?.Invoke(buffers);
        }

调用示例

SuperSerialPort ssp = new SuperSerialPort();
ssp.DataReceived = new Action<byte[]>(DataReceived);
/// <summary>
/// 回调方法
/// </summary>
/// <param name="res"></param>
 private void DataReceived(byte[] res)
{
            //处理串口返回的数据
}

目前只封装了这些需要的话以后再加，，，，，，，，，有疑问或者更好封装方法的可以加QQ群:765907694 交流
