Winform 关于文字移动的问题！！？？
小弟现在想做一个关于label从下往上移动的窗体。基本功能已实现，但效果不理想，不理想在哪呢？在一段文字走完了以后，会出现一屏的空白。望大侠们赐教下！！！
基本代码如下：
int loc_text = 0;
private void timer1_Tick(object sender, EventArgs e)
{
int FWidth = this.panel1.Width;
int FHeight = this.panel1.Height;
Point LPos = new Point(this.label1.Location.X, this.label1.Location.Y);
if (LPos.Y < FHeight)
{
if (LPos.Y < -loc_text)
{
this.label1.Location = new Point(0, this.Height - 72); return;
}
this.label1.Location = new Point(LPos.X, LPos.Y - 10);
return;
}
else
{
this.label1.Location = new Point(0, 0);
}
}
private void JCZ_SendNews_Load(object sender, EventArgs e)
{
this.label1.Location = new Point(0, this.Height - 72);
label1.Text = " 紧急通知\n由于近期物价高涨，燃油价格也高涨，反正就是什么都贵了。为了体现中国加入WTO与国际接轨的精神，本店铺也将提价10%，表示对国家的物质文明建设的贡献！";
int sumChar = label1.Text.Length;
int rowCount = (sumChar / 10) + 1;
label1.Height = rowCount * 100;
loc_text = rowCount * 100;
label1.Size = new Size(1024, label1.Height);
label1.Font = new Font("黑体", 72);
label1.ForeColor = Color.Red;
this.BackColor = Color.Black;
this.timer1.Enabled = true;
this.timer1.Interval = 300;
this.timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
int FWidth = this.panel1.Width;
int FHeight = this.panel1.Height;
Point LPos = this.label1.Location;
if (LPos.Y < FHeight)
{
if (LPos.Y < -label1.Height)
{
this.label1.Location = new Point(0, this.Height - 72);
return;
}
this.label1.Location = new Point(LPos.X, LPos.Y - 10);
}
else
{
this.label1.Location = new Point(0, 0);
}
}
private void JCZ_SendNews_Load(object sender, EventArgs e)
{
this.label1.Location = new Point(0, this.Height - 72);
label1.Text = " 紧急通知\n由于近期物价高涨，燃油价格也高涨，反正就是什么都贵了。为了体现中国加入WTO与国际接轨的精神，本店铺也将提价10%，表示对国家的物质文明建设的贡献！";
int sumChar = label1.Text.Length;
int rowCount = (sumChar / 10) + 1;
label1.Height = rowCount * 100;
label1.Size = new Size(1024, label1.Height);
label1.Font = new Font("黑体", 72);
label1.ForeColor = Color.Red;
//this.BackColor = Color.Black;
this.timer1.Enabled = true;
this.timer1.Interval = 300;
this.timer1.Start();
}
