求C# 控件拖动控件代码?

我想搞一个PictureBox控件, 但不知道如果才可以拖动控件, 请高手指点一下 拖动的同时还要有窗体的阴影,, 谢谢了.! 只有10分了

拖动可以这样（Sorry，窗体阴影不知道- -）：
类中添加变量：
private bool isDragging = false; //拖中
private int currentX = 0, currentY = 0; //原来鼠标X,Y坐标
然后假设PictureBox控件叫做pictureBox1。
给它添加MouseDown，MouseUp，和MouseMove事件，事件处理函数分别如下：

private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
isDragging = true; //可以拖动
currentX = e.X;
currentY = e.Y;
}

private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
{
isDragging = false;
}

private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
{
if (isDragging)
{
pictureBox1.Top = pictureBox1.Top + (e.Y - currentY);
pictureBox1.Left = pictureBox1.Left + (e.X - currentX);
}
}
