01-5 滚动字幕动画窗体

设置窗体的TransparencyKey为Control，效果为显示窗体为透明。

然后插入代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace Case01_5
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            this.timer1.Interval = 10;//时间间隔为10
            this.timer1.Enabled = true;
            this.WindowState = FormWindowState.Maximized;////窗口最大化
        }
        private void timer1_Tick(object sender, EventArgs e)
        {
            label1.Left = label1.Left - 3;
            if (label1.Right < 0)
            {
                label1.Left = this.Width;
            }
        }
        
        
        //点击label1时候发生的动作
        private void label1_Click(object sender, EventArgs e)
        {
            this.Close();
        }
    }
}
