private void Form1_Load(object sender, EventArgs e)
        {
            this.label1.Location = new Point(0, 0);
        }
         int xPox = 0;
        bool ist = true;
        private void timer1_Tick(object sender, EventArgs e)
        {
            this.label1.Location = new Point(xPox,this.label1.Location.Y);            if (xPox == this.Width-this.label1.Size.Width)
                ist = false;
            if(xPox==0)
                ist = true;
            if (ist)
                xPox++;
            else
                xPox--;
        }

Answer 4

bool ist = true;//为true时字幕向右走，反之向左走 
       private void timer1_Tick(object sender, EventArgs e)
        {
            this.label1.Location = new Point(xPox,this.label1.Location.Y);            if (xPox == this.Width-this.label1.Size.Width)//字幕到了最右边
                ist = false;
            if(xPox==0)//字幕到了最左边
                ist = true;
            if (ist)
                xPox++;//右走
            else
                xPox--;//左走
        }

一楼的似乎实现不了的……
试试这个：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;namespace 欢迎条
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        private void Form1_Load(object sender, EventArgs e)
        {
            this.timer1.Interval = 10;
            this.timer1.Enabled = true;
            //this.WindowState = FormWindowState.Maximized;
        }
        private void timer1_Tick(object sender, EventArgs e)
        {
            label1.Left = label1.Left - 2;
            if (label1.Right<0) 
            {
                label1.Left = this.Width;
            }
        }        private void button1_Click(object sender, EventArgs e)
        {
            this.Close();
        }
    }
}

Answer 6

抱歉了，一楼的是可以的，实现的是字体向左向右移动的public partial class Form1 : Form
    
    {        public Form1()
        
        {            InitializeComponent();
        
        }
        private void Form1_Load(object sender, EventArgs e)        {            this.timer1.Interval = 1;            this.timer1.Enabled = true;            //this.WindowState = FormWindowState.Maximized;        }        bool i = true;        int xPox;        private void timer1_Tick(object sender, EventArgs e)        {            this.label1.Location = new Point(xPox, this.label1.Location.Y);            if (xPox > this.Width - this.label1.Size.Width+label1.Width)//字幕到了最右边
                       i = false;            if (xPox < 0-label1.Width)//字幕到了最左边                i = true;            if (i)                xPox+=5;//右走            else                xPox-=5;//左走
        }        private void label1_Click(object sender, EventArgs e)        {            this.Close();        }    }

Answer 7

LBG.Text = LBG.Text.Substring(1) + LBG.Text[0];
这个是最好用的
LBG是标签
不明白的找我
还有啊，别忘记TMG.Stop();启动记时器

Answer 8

            label1.Left = label1.Left - 2;
            if (label1.Right < 0)
            {
                label1.Left = this.Width;
            }
