c# 当在pictureBox上单击时响应鼠标事件（着急，在线等）

[MUTOUYIHAO]

本来是想实现用鼠标拖动pictureBox中的图片，但是当鼠标在图片上单击时没反应，在窗体的空白处却有反应。代码如下：
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
// this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.pictureBox1_MouseDown);
this.MouseDown +=new MouseEventHandler(pictureBox2_MouseDown);
}
private void pictureBox2_MouseDown(object sender, MouseEventArgs e)
{
//wselected = true;
//p.X = e.X;
//p.Y = e.Y;
MessageBox.Show("down");
}
}
怎样才能使当鼠标在图片上单击时有反应啊？更够给出移动图片的全部代码就更好了，整一天了全糊涂了，比较着急……
贴出全部代码或发个工程到[e-mail]者追加分数。谢谢

写在MouseMove事件里试试
if(右键点下)

应该在 PictureBox 这个控件中的 MouseClick 事件里面编程 ，你的好像是 Form 里面的MouseDown()事件当然 在空白区域有效了

        public void pictureBox1_MouseDown(object sender, MouseEventArgs e)
        {

            if (pictureBox1.Image != null)
            {
                a = e.Location.X;
                b = e.Location.Y;
                pictureBox1.Cursor = System.Windows.Forms.Cursors.Hand;
            }
        }


        private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
        {

             
                    pictureBox1.Cursor = System.Windows.Forms.Cursors.Default;
                    c = e.Location.X;
                    d = e.Location.Y;
                    locateX += (c - a);
                    locateY += (d - b);
                    Graphics g = pictureBox1.CreateGraphics();
                    g.Clear(SystemColors.Control);
                    g.DrawImage(pictureBox1.Image, locateX, locateY,
                        pictureBox1.Image.Width , pictureBox1.Image.Height);
                    g.Dispose();
               
            
        }

a和b全局变量

a,b,c,d全局变量，保存图像位置
