我尝试这个代码但它不起作用，当我点击标题栏时，它隐藏，我不知道我该怎么做。

i try this code but it doesnt work and when i click at the title bar, it hides, i dont know what shoud i do.

private bool Dragging = false;
private Point start_point = new Point(0, 0);

        {
            Dragging = true;
            start_point = new Point(e.X, e.Y);
        }

        private void UserControlDesign_MouseUp(object sender, MouseEventArgs e)

            if (Dragging)
            {
                Point p1 = new Point(e.X, e.Y);
                Point p2 = this.FindForm().PointToScreen(p1);
                Point p3 = new Point(p2.X - start_point.X, p2.Y - start_point.Y);
                this.FindForm().Location = p3;
            }
        }

推荐答案

MouseDown事件中给出的坐标位于客户端空间而不是屏幕。

您不需要使用PointToScreen方法转换鼠标坐标。

The coordinate given in the MouseDown event are in the client space not the screen.
You do not need to transform the mouse coordinate using the PointToScreen method.
