C#循环滚动字幕,timer,从左至右,从右至左,暂停ShinePans -电脑资料

    Lable的Left属性是可以更改的,但是 Right属性不可以更改,所以我们可以利用 这个特点做自加 自减运算

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;namespace 滚动字幕{    public partial class Form1 : Form. {        public Form1()        {            InitializeComponent();        }        private void timer1_Tick(object sender, EventArgs e)        {            this.label2.Left += 8;  //向右移动3个像素            if(this.label2.Left>this.Width)            {                this.label2.Left = 0-label2.Width;   //标签左位置为当前控件宽度            }        }        private void button1_Click(object sender, EventArgs e)        {            this.timer2.Stop();            this.timer1.Start();  //打开计时器        }        private void button2_Click(object sender, EventArgs e)        {            this.timer1.Stop(); //停止计时器            this.timer2.Stop();        }        private void button3_Click(object sender, EventArgs e)        {            this.timer1.Stop();            this.timer2.Start();        }        private void timer2_Tick(object sender, EventArgs e)        {            this.label2.Left -= 8;  //向右移动3个像素            if (this.label2.Right <0)            {                this.label2.Left = this.Width;   //标签左位置为当前控件宽度            }        }    }}
