关于 MouseMove 的处理问题，急~~~ 请各位指点

Question

我现在在做一个CE 项目，  里面设计到 一个列表滚动的问题
  我的做法是这样的，
private void PB_mousemove(object sender, PaintEventArgs e)
{
   
            Graphics g=pb.createGraphics();           g.DrawRectangle(new Pen(Color.Red,1.5F),new Rectangle(0,e.Y,200,200));}
   就是在 mousemove 事件里捕获鼠标点，然后画, 可是当运行起来的时候发现
  1。画面不流畅，
  2。我按住鼠标移动的时候，并没有实时去绘制 我的矩形  请各位帮忙看，我要怎么解决？ 在线等到

public void DrawImage(int x, int y, Graphics g)
        {
            g.FillRectangle(blueBrush, new Rectangle(x, y, 165, 40));
            g.DrawRectangle(penRectangle, new Rectangle(x, y, 165, 40));
            g.DrawLine(penRectangle, x, y + 20, x + 165, y + 20);
            g.DrawLine(penRectangle, x + 55, y, x + 55, y + 40);
            g.DrawLine(penRectangle, x + 110, y, x + 110, y + 40);
            g.DrawString("起始时间", new Font("黑体", 8), Brushes.Black, new Point(x + 3, y + 5));
            g.DrawString(DateTime.Now.ToShortDateString(), new Font("宋体", 8), Brushes.Black, new Point(x + 3, y + 5 + 20));
            g.DrawString("结束时间", new Font("黑体", 8), Brushes.Black, new Point(x + 3 + 55, y + 5));

            g.DrawString("持续时间", new Font("黑体", 8), Brushes.Black, new Point(x + 3 + 110, y + 5));
            g.DrawString("N天", new Font("黑体", 8), Brushes.Black, new Point(x + 13 + 110, y + 5 + 20));
        }
        public void DrawRectangle(Point p, Graphics g)
        {

            int x;
            int y;            if (p.X < 180)
            {
                if (p.Y < 60)
                {
                    x = p.X + 20;
                    y = p.Y + 20;
                    DrawImage(x, y, g);
                    return;
                }
                x = p.X + 20;
                y = p.Y - 60;
                DrawImage(x, y, g);            }
            else if (p.Y < 60)
            {
                x = p.X - 20 - 159;
                y = p.Y + 20;
                DrawImage(x, y, g);
            }
            else
            {
                x = p.X - 20 - 159;
                y = p.Y - 20 - 40;
                DrawImage(x, y, g);
            }
        } private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
        {
            Graphics g = pictureBox1.CreateGraphics();
                DrawRectangle(new Point(e.X, e.Y), pictureBox1.CreateGraphics());
        }
希望对你有帮助！

我的要很简简， 大家在现在都用手机吧， 在手机列表显示条目的时候会有一个滚动的效果，当鼠标<触屏>移动的时候画面要上下翻动， 但是要保证其连惯性 

Answer 3

PB是什么？PictureBox?那画在bitmap上赋给PictureBox.Image啊

Answer 4

在MouseDown里记下按下时的点，在MouseMove里执行操作，在MouseUp里停止
