C#定时器的三种实现方法（System.Timers.Timer、System.Windows.Forms.Timer、System.Threading.Timer）

用了三种不同方法来实现定时任务，分别是

System.Timers.Timer、System.Windows.Forms.Timer、System.Threading.Timer 这三种方式实现了 定时器功能

        public int currentCount = 0;
        //定义Timer类
        System.Threading.Timer threadTimer;
        //定义委托
        public delegate void SetControlValue（object value）;

        public FrmMain（）
        {
            InitializeComponent（）;
        }

        private void FrmMain_Load（object sender EventArgs e）
        {
            InitTimer（）;
        }

        /// 

        /// 初始化Timer类
