									  {

									    public Form1()

									    {

									      InitializeComponent();

									    }

									    private Label label = new Label();

									    public string text = "csdn baihe_591";

									    private void Form1_Load(object sender, EventArgs e)

									    {

									      this.label.Location = new Point(149, 13);

									      this.label.Size = new Size(134, 16);

									      this.Controls.Add(label);

									      this.label.Text = "";

									      this.timer1.Enabled = true;

									      this.timer1.Interval = 500;

									      p = new PointF(this.label.Size.Width, 0);

									    }

									    PointF p;

									    Font f = new Font("宋体", 10);

									    Color c = Color.White;

									    string temp;

									    private void timer1_Tick(object sender, EventArgs e)

									    {

									      Graphics g = this.label.CreateGraphics();

									      SizeF s = new SizeF();

									      s = g.MeasureString(text, f);//测量文字长度

									      Brush brush = Brushes.Black;

									      g.Clear(c);//清除背景

									      if (temp != text)//文字改变时,重新显示

									      {

									        p = new PointF(this.label.Size.Width, 0);

									        temp = text;

									      }

									      else

									        p = new PointF(p.X - 10, 0);//每次偏移10

									      if (p.X <= -s.Width)

									        p = new PointF(this.label.Size.Width, 0);

									      g.DrawString(text, f, brush, p);

									    }

									  }
