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));

        }
