想让一个label在form窗体上间隔一段时间闪烁一次隔一段时间在闪烁一次

Question

想让一个label在form窗体上间隔一段时间闪烁一次隔一段时间在闪烁一次间隔时间成1,3,5....2n-1,递增的;
不要用timer控件,想用多线程using System.Threading
不知道如何操作.大家帮看下.

Answer 1

for循环
if 1,3,5....2n-1
Sleep 时间
把label透明度设为0
否则 100

Answer 2

创建一个线程，在线程类里面定义一个label控件，在界面上拖一个label控件，
ClassStartThread startThread = new ClassStartThread( this.label1);
            Thread st = new Thread(new ThreadStart(startThread.StartThread));
            tUdpThread.IsBackground = true;
            tUdpThread.Start();
[code=C#]
    class ClassStartThread
    {
        private int tm=0;
        private int lt=0;
        private Label label1;
        public ClassStartUdpThread(Label label2)
        {
            this.label1 = label2;
            tm = DateTime.Now.Second;
            tm += DateTime.Now.Minute * 60;
            tm += DateTime.Now.Hour * 3600;
        }
        public  void StartThread()
        {
            for(int i=0;;i++)
            {
                lt= DateTime.Now.Second;
                lt += DateTime.Now.Minute * 60;
                lt += DateTime.Now.Hour * 3600;
                if((lt-tm)==((2*i)-1))
                {
                    this.label1.Enabled=false;
                }
                Thread.Sleep(10);
                this.label1.Enabled=true;
            }
        }
    }[/code]大致就这样，随便写的， 也不知道有没有错误，有错误，请楼下的指正！在此先谢过了！

Answer 3

闪烁？可见->不可见->可见->.....  这样？那加个timer就搞定了要想显眼，还是定时改变label的字体颜色好些

Answer 4

quartz调度组件可完成你要的效果

Answer 5

为什么不用timer控件，以下的代码，timer1用于显示闪的效果，timer2用于控制你所谓的递增间隔的时间闪烁的控制，更简单更容易理解

    partial class Form1

        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
