Timer组件

1、常用属性

Interval 用于获取或设置Timer组件Tick事件发生的时间间隔，属性值不能小于1

制作左右飘摇窗体

        private void timer1_Tick(object sender, EventArgs e)
        {
            Rectangle rect = Screen.GetWorkingArea(this);//获取屏幕大小
            if (this.Left != (rect.Width - this.Width))
            {
                this.Left++;//窗体向右移动
                this.Top += 1;//窗体向下移动
            }
            else
            {
                timer1.Enabled = false;//停用Timer组件
                timer2.Enabled = true;//启用Timer组件
            }
        }
        private void timer2_Tick(object sender, EventArgs e)
        {
            Rectangle rect = Screen.GetWorkingArea(this);//获取屏幕大小
            if (this.Left == 0)
            { 
                timer2.Enabled = false;//停用Timer组件
                timer1.Enabled = true;//启用Timer组件
            }
            else
            {
                this.Left--;//窗体向左移动
                this.Top -= 1;//窗体向上移动
            }
        }

倒计时

//变量用于存储年、月、日、时、分、秒
        public long LogYear, logMonth, logDay, logHour, logMinte, logSencon;
        private void timer1_Tick(object sender, EventArgs e)
        {
            DateTime get_time1 = DateTime.Now;//得到当前系统时间
            DateTime sta_ontime1 = Convert.ToDateTime(//得到世界杯开幕时间
                Convert.ToDateTime("2014-10-13 00:00:00"));
           txtYear.Text = DateAndTime.DateDiff(//计算相隔年数
               "yyyy", get_time1, sta_ontime1,
               FirstDayOfWeek.Sunday, 
               FirstWeekOfYear.FirstFourDays).ToString();
           txtMonth.Text = DateAndTime.DateDiff(//计算相隔月数
               "m", get_time1, sta_ontime1, 
               FirstDayOfWeek.Sunday, 
               FirstWeekOfYear.FirstFourDays).ToString();
           textday.Text = DateAndTime.DateDiff(//计算相隔天数
               "d", get_time1, sta_ontime1, 
               FirstDayOfWeek.Sunday, 
               FirstWeekOfYear.FirstFourDays).ToString();
           txtHour.Text = DateAndTime.DateDiff(//计算相隔小时数
               "h", get_time1, sta_ontime1, 
               FirstDayOfWeek.Sunday, 
               FirstWeekOfYear.FirstFourDays).ToString();
           txtmintue.Text = DateAndTime.DateDiff(//计算相隔分钟数
               "n", get_time1, sta_ontime1, 
               FirstDayOfWeek.Sunday, 
               FirstWeekOfYear.FirstFourDays).ToString();
           txtsecon.Text = DateAndTime.DateDiff(//计算相隔秒数
               "s", get_time1, sta_ontime1, 
               FirstDayOfWeek.Sunday, 
               FirstWeekOfYear.FirstFourDays).ToString();
           textBox1.Text = DateTime.Now.ToString();
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            textBox2.Text = //显示世界杯时间
                "2014-10-13  00:00:00" + "　　星期五";
            timer1.Enabled = true;//开启计时器
        }

制作动画

        private void tmr_Action_Tick(object sender, EventArgs e)
        {
            CreateGraphics().DrawImage(//在窗体中绘制图片信息
                Image.FromFile(
                (index++ > 7 ? (index = 1) : index).
                ToString() + ".jpg"), new Point(0, 0));
        }
