winform跑马灯

以下是实现WinForm跑马灯效果的方法：

1. 使用Timer控件和Label控件实现跑马灯效果：

using System;
using System.Windows.Forms;

namespace WindowsFormsApp
{
    public partial class Form1 : Form
    {
        private Timer timer;
        private Label label;

        public Form1()
        {
            InitializeComponent();
            InitializeTimer();
            InitializeLabel();
        }

        private void InitializeTimer()
        {
            timer = new Timer();
            timer.Interval = 100; // 设置定时器间隔时间，单位为毫秒
            timer.Tick += Timer_Tick;
            timer.Start();
        }

        private void InitializeLabel()
        {
            label = new Label();
            label.Text = "这是一个跑马灯效果的Label";
            label.Location = new System.Drawing.Point(10, 10);
            label.AutoSize = true;
            Controls.Add(label);
        }

        private void Timer_Tick(object sender, EventArgs e)
        {
            // 每次定时器触发时，将Label的位置向左移动一定距离
            label.Left -= 5;

            // 当Label完全移出窗口时，将其重新放置到窗口右侧
            if (label.Right < 0)
            {
                label.Left = Width;
            }
        }
    }
}

2. 使用PictureBox控件和Timer控件实现跑马灯效果：

using System;
using System.Windows.Forms;

namespace WindowsFormsApp
{
    public partial class Form1 : Form
    {
        private Timer timer;
        private PictureBox pictureBox;

        public Form1()
        {
            InitializeComponent();
            InitializeTimer();
            InitializePictureBox();
        }

        private void InitializeTimer()
        {
            timer = new Timer();
            timer.Interval = 100; // 设置定时器间隔时间，单位为毫秒
            timer.Tick += Timer_Tick;
            timer.Start();
        }

        private void InitializePictureBox()
        {
            pictureBox = new PictureBox();
            pictureBox.Image = Properties.Resources.marquee_image; // 设置跑马灯图片
            pictureBox.SizeMode = PictureBoxSizeMode.AutoSize;
            pictureBox.Location = new System.Drawing.Point(10, 10);
            Controls.Add(pictureBox);
        }

        private void Timer_Tick(object sender, EventArgs e)
        {
            // 每次定时器触发时，将PictureBox的位置向左移动一定距离
            pictureBox.Left -= 5;

            // 当PictureBox完全移出窗口时，将其重新放置到窗口右侧
            if (pictureBox.Right < 0)
            {
                pictureBox.Left = Width;
            }
        }
    }
}
