我需要收听机器中的所有串口。假如我的机器有4个串口,我必须创建4个线程并分别用附加的线程开始监听每个端口。
我用这段代码来获取机器中的端口数量。
private SerialPort comPort = new SerialPort();
public void GetAllPortNamesAvailable()
{
string[] ports = SerialPort.GetPortNames();
foreach (string port in ports)
{
//How to start a thread here ??
}
}
public void AssignThreadtoPort()
{
string msg = comPort.ReadLine();
this.GetMessageRichTextBox("Message : " + msg + "\n");
}
阅读评论后,我正在使用此代码,但没有收到消息..问题是什么?
public void AssignThreadsToPorts()
{
string[] ports = SerialPort.GetPortNames();
foreach (string port in ports)
{
SerialPort sp = new SerialPort();
sp.PortName = port;
sp.Open();
new Thread(() =>
{
if (sp.IsOpen)
{
string str = sp.ReadLine().ToString();
MessageBox.Show(str);
}
}).Start();
}
}

您可以使用thread pool:
string[] ports = SerialPort.GetPortNames();
foreach (string port in ports)
{
ThreadPool.QueueUserWorkItem(state =>
{
// This will execute in a new thread
});
}
或手动创建并启动threads:
string[] ports = SerialPort.GetPortNames();
foreach (string port in ports)
{
new Thread(() =>
{
// This will execute in a new thread
}).Start();
}
