winform怎么实现文字的上下滚动

winform怎么实现文字的上下滚动，就像电视台选秀节目中宣传短信发送方法那样的效果

Timer+Graphics

说详细些，最好有代码

[SkyAPI_COM]

在窗体上添加一个LABEL，启动一个线程，在线程中设置LABEL的TEXT属性～～

滚动可以算字符串

参考一下这个代码：
public class ScrollWord:Form
{
private Rectangle m_WordRect;
private Timer timer;
public ScrollWord()
{
timer = new Timer();
timer.Interval = 100;
timer.Tick += new EventHandler(timer_Tick);
timer.Start();
}
protected override void Dispose(bool disposing)
{
if (disposing)
{
this.timer.Dispose();
}
base.Dispose(disposing);
}
protected override void OnTextChanged(EventArgs e)
{
base.OnTextChanged(e);
Size size = TextRenderer.MeasureText(this.Text, this.Font);
this.m_WordRect = new Rectangle(this.m_WordRect.X, this.m_WordRect.Y, size.Width + 5, this.ClientRectangle.Height);
}
void timer_Tick(object sender, EventArgs e)
{
if (this.m_WordRect.Right < this.ClientRectangle.Left)
{
this.m_WordRect.X = this.ClientRectangle.Right;
}
else
{
this.m_WordRect.X--;
}
this.Invalidate();
}
protected override void OnPaint(PaintEventArgs e)
{
using (StringFormat format = new StringFormat())
{
format.LineAlignment = StringAlignment.Center;
format.Alignment = StringAlignment.Center;
e.Graphics.DrawString(this.Text, this.Font, SystemBrushes.ControlText, this.m_WordRect, format);
}
}
}
