C#中在控件中画图并用TIMER控件进行控制方法的实现

private void timer2_Tick(object sender, EventArgs e)
{
imageSizeX = imageSizeX + 100;
imageSizeY = imageSizeY + 106;
imageX = imageX - 50;
imageY = imageY - 53;
if (imageX <= 12)
{
imageX = 0;
imageY = 0;
imageSizeX = 1024;
imageSizeY = 768;
timer2.Enabled = false;
}
this.lbl_result.Invalidate();

}

private void lbl_result_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
Pen p = new Pen(Color.Gray, 10);
g.SmoothingMode = SmoothingMode.HighQuality;
g.FillRectangle(Brushes.Yellow,new Rectangle(new Point(0,0),
this.lbl_result.ClientSize));
g.DrawImage(this.lbl_result.Image, imageX, imageY, imageSizeX, imageSizeY);
if (imageX == 0)
{

g.DrawString(res_temp, new Font("Arial", 45), Brushes.Red, new Point(360, 320));
}
//this.lbl_result.Text = res_temp;
//g.DrawImage(this.lbl_result.Image, 0, 0, 1024, 768);
}
