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

    Lable的Left属性是能够更改的,可是 Right属性不能够更改,所以我们能够利用 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
                }
            }
        }
    }
