C# 自定义 定时器

创建类：TimerTool.cs

namespace 命名空间
{
    public class TimerTool
    {
        private static Dictionary timers = new Dictionary();

        /// 

        /// settimeout定时器
        /// 
        /// 触发事件
        /// 触发间隔
        /// 
        public static string SetTimeout(Action action, double interval)
        {
            string timerId = System.Guid.NewGuid().ToString();
            Timer timer = new Timer(interval);
            timer.Elapsed += (object sender, ElapsedEventArgs e) =>
            {
                timer.Enabled = false;
                action();
            };
            timer.Enabled = true;
            timers.Add(timerId, timer);
            return timerId;
        }

        /// 

        /// 销毁定时器
        /// 
        /// 定时器id
        public static void ClearTimeout(string timerId)
        {
            if (timers.ContainsKey(timerId))
            {
                var timer = timers[timerId];
                //timer.Enabled = false;
                timer.Close();
                timers.Remove(timerId);
            }
        }
    }
}

 用的时候就可以直接调用它

public static string timerId = string.Empty; //定时器

            timerId = TimerTool.SetTimeout(() =>
            {
                //你要延时的代码
                
            }, 1000);  //1000毫秒，可自设
