Hi,
I have a Thread Function that reads data continuously from the Serial Port like this:

C#

SerialPort _serialPort;
_serialPort = new SerialPort();
_serialPort.Open();
Thread ReceiveDataFromSerial = new Thread(ReadData)
Thread.Start()
byte[] buffer = new byte[20];
public void ReadData()
{

  while(true)
   {
     _serialPort.Read(buffer,0,20);
   }
}

I need to read data from Six Serial ports using the same Thread Function.
How can I make Thread function that accept SerialPort as parameter and use that parameter to read from that particular Serial Port.

Thanks

I know that's been covered by Jon Skeet in here Multi-threading in .NET: Introduction and suggestions[^]

The general gist, I would have thought was something like this,

SerialPort _serialPort = ...
Thread thread = new Thread(() => ReadData(_serialPort, buffer));
thread.Start();
...
public void ReadData(SerialPort _serialPort, byte[] buffer)
{
  while(true)
  {
    _serialPort.Read(buffer, 0, 20);
  }
}

although I think the passing/handling of the buffer may require more thought/attention than I've paid to it
