贴 一个Thread 运行代码

请将运行函数放在MainMethod()中!

详细:
1、带有 Init()函数;
2、带有Abort()函数;另设计了AbortAsync()任务。
3、加入Watchdog!

using System;
using System.Diagnostics;
using System.Threading;
using System.Threading.Tasks;

namespace DemoModbus
{
    class ModbusRun
    {
        public static Task<bool> TaskWatchdog;

        public static void Init()
        {
            threadModbusRun = new Thread(new ThreadStart(() => IsEnd = FucAFlow()));
            threadModbusRun.Start();

            TaskWatchdog = new Task<bool>(FucWatchdog, TaskCreationOptions.LongRunning);
            TaskWatchdog.Start();
        }




        /// <summary>
        /// 函数:线程结束功能。运行时间不大于2s。
        /// </summary>
        public static void Abort()
        {
            // bool res = false;
            LoopEnable = false;
            Stopwatch sw_AlarmDealy = new Stopwatch();
            sw_AlarmDealy.Start();
            while (!IsEnd && sw_AlarmDealy.ElapsedMilliseconds < 2000) ;
            sw_AlarmDealy.Stop();
            if (!IsEnd)
            {
                threadModbusRun.Abort();
            }
            return;
        }
