收到读行时如何调用功能
原标题:How to call function when readLine is received

我的程式需要通过序列端口接收字符串。 问题在于当没有输入时程序会被卡在 ReadLine 上。 当 SP. readLine 读取一行时, 是否有一种方法可以调用函数开始读取 read? < precode> 避免 GetInput () {SiralPord SP = 新的SiralPortword (); SP. PortName = “ COM3” ; SP. Open (); 字符串线 =字符串. Empty; {line = SP. ReadLine (); 应用程序. Dovents (); { startReading () } start Reading () {}

最佳回答
    private void GetInput()
    {
        SerialPort SP = new SerialPort();
        SP.PortName = "COM3";
        SP.DataReceived += new SerialDataReceivedEventHandler(SP_DataReceived);
        SP.Open();
    }

    private void SP_DataReceived(object sender, SerialDataReceivedEventArgs e)
    {
        SerialPort serialPort = (SerialPort)sender;
        string line = serialPort.ReadLine();
        StartReading();
    }

    private void StartReading()
    {
    }
