经过大量的研究，我仍然难倒了。我有一个连续读取数据的串口对象。我所能做的就是生成dataReceived事件，与端口通信，并将接收到的值输出到调试窗口。所以，我很确定这一切都在身体上运作。问题是当我尝试将串行端口输出传递给我的原始线程时出现错误。它说我不能有线程交叉讨论（或者是那种效果）。我一直在尝试使用backgroundWorker，但我不确定这是我想要的解决方案，加上我的新手技能有点超出我的头脑。我试图使用调用，但该方法似乎不可用。 （我可能是从错误的对象调用？）无论如何部分在下面。线程之间的串口通信
namespace Photometer
{
class csRadiometerILT1700
{
//manufacturer specs for baud rate, databits, and stop bits
static string portName="COM1";
static int baudRate = 1200;
static int dataBits = 8;
//instantialize a serial port object for the Radiometer
private SerialPort RadiometerSerial = new SerialPort(portName, baudRate, Parity.None, dataBits, StopBits.One);
//constructor
//public csRadiometerILT1700(Form ParentForm, Chart outputChart)
public csRadiometerILT1700()
{
//two handshaking properties of the ILT1700. Handshaking is enabled and
//http://stackoverflow.com/questions/6277619/problem-reading-serial-port-c-net-2-0-to-get-weighing-machine-output
RadiometerSerial.Handshake= Handshake.RequestToSend;
RadiometerSerial.DtrEnable = true;
RadiometerSerial.DataReceived += new SerialDataReceivedEventHandler(RadiometerSerial_DataReceived);
}
public void openPort()
{
if (!RadiometerSerial.IsOpen)
{
RadiometerSerial.Open();
}
}
public void closePort()
{
RadiometerSerial.Close();
}
string RadiometerVoltageReadingString;
int RadiometerVoltageReadingInt;
private void RadiometerSerial_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
//It's here that this.invoke()... cannot be called.
RadiometerVoltageReadingString= (RadiometerSerial.ReadExisting().ToString()); //y-value
Debug.Print(RadiometerVoltageReadingString.ToString());
makeRadioReadingDouble(RadiometerVoltageReadingString);
}
private void makeRadioReadingDouble(string inputVoltageString)
{
List<double> outputVoltageDouble=new List<double>(2);
if (!(inputVoltageString == "\r\n" || inputVoltageString == ""))
{
string[] voltageValAndExpo = inputVoltageString.Split(new string[] { "e", "\r\n" }, StringSplitOptions.RemoveEmptyEntries);
for (int inCounter = 0; inCounter < voltageValAndExpo.Count(); inCounter=inCounter+2)
{
double voltageVal = Convert.ToDouble(voltageValAndExpo[inCounter]);
double voltageExpo = Convert.ToDouble(voltageValAndExpo[inCounter + 1]);
outputVoltageDouble.Add(Math.Pow(voltageVal, voltageExpo));
}
}
}
}
}
这是当我形成任何有识之士的赞赏码
csRadiometerILT1700 Radiometer;
...
Radiometer = new csRadiometerILT1700();
Radiometer.openPort();
加载所有调用。
编辑： 我改变了我的csRadiometerILT1700构造函数
public csRadiometerILT1700(Form inputForm)
{
//inputForm.Invoke(
//two handshaking properties of the ILT1700. Handshaking is enabled and
//http://stackoverflow.com/questions/6277619/problem-reading-serial-port-c-net-2-0-to-get-weighing-machine-output
RadiometerSerial.Handshake= Handshake.RequestToSend;
RadiometerSerial.DtrEnable = true;
RadiometerSerial.DataReceived += new SerialDataReceivedEventHandler(RadiometerSerial_DataReceived);
inputForm.Invoke(DataReceived);
}
，并在csRadiometerILT1700类中声明
public event Delegate DataReceived;
。但是这给了我“数据接收必须是委托类型”的错误。我现在如何解决这个问题？我在正确的轨道上吗？
请勿从ctor中调用。以下是设置事件的链接：http：//stackoverflow.com/questions/2448487/how-to-dispatch-events-in-c/2448530#2448530 –
当收到有意义的数据时，您的课程应该提高其事件。将它打包成一个EventArgs派生类。表单订阅（+ =）并在其处理程序中调用。 –
