小编Dav*_*vid的帖子

我正在为我的应用程序开发一个通信管理器,其设计如下:

ICommunicator接口,一般通信器.

public interface ICommunicator
{
    bool openConnection();
    bool closeConnection();

    bool isConnectionOpen();
    Form getConfigurationForm();

    void Data_Input(object sender, EventArgs e);
}

目前,一个具体的沟通者是SerialCommunicator:

public class SerialCommunicator : ICommunicator
{
    public delegate bool setPortDelegate(string portName);
    public delegate bool setBaudRateDelegate(int baudRate);

    private SerialPort serial;

    public SerialCommunicator()
    {
        serial = new SerialPort();
        loadDefaultSerialPreset(serial);
        serial.DataReceived += Data_Input;
    }

    public bool openConnection()
    {
        if (serial.IsOpen)
        {
            return false;
        }
        try
        {
            serial.Open();
        }
        catch (Exception)
        {
            //could not open the port
            return false;
        }

        return serial.IsOpen;
    } …
