MUGAN's close. The Point you'll get from MouseEventArgs is the "screen" point of the mouse, where 0,0 is the top left of the entire monitor or desktop (however you want to think of it). To convert that to a "client" point within the PictureBox control, where 0,0 is the top left of that PictureBox, you'll need to use the Control.PointToClient() method:
MUGAN 快到了。您将从 MouseEventArgs 获得的 Point 是鼠标的“屏幕”点，其中 0,0 是整个显示器或桌面的左上角（无论您想怎么想）。要将其转换为 PictureBox 控件中的“客户端”点，其中 0,0 是该 PictureBox 的左上角，您需要使用 Control.PointToClient() 方法：
private void pb_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
Point mouseDownLocation = (Control)sender.PointToClient(new Point(e.X, e.Y));
//here goes your if condition ...
}
