C#多线程串口通信
这是一个非常经典的C#串口多线程实例，把部分代码发送来让大家看看
using System;
using System.IO;
using System.IO.Ports;
using System.Collections;
using System.Threading;
namespace Termie
{
/// CommPort class creates a singleton instance
/// of SerialPort (System.IO.Ports)
/// When ready, you open the port.
///
/// CommPort com = CommPort.Instance;
/// com.StatusChanged += OnStatusChanged;
/// com.DataReceived += OnDataReceived;
/// com.Open();
///
/// Notice that delegates are used to handle status and data events.
/// When settings are changed, you close and reopen the port.
///
/// CommPort com = CommPort.Instance;
/// com.Close();
/// com.PortName = "COM4";
/// com.Open();
///
///
public sealed class CommPort
{
SerialPort _serialPort;
Thread _readThread;
volatile bool _keepReading;
//begin Singleton pattern
static readonly CommPort instance = new CommPort();
// Explicit static constructor to tell C# compiler
// not to mark type as beforefieldinit

{
}

}
