Answer 1

您需要使用PointToClient

的Form方法

var relativePoint = this.PointToClient(new Point(X, Y));

// Or

var relativePoint = this.PointToClient(Cursor.Position);

Control.PointToClient Method (Point)

  

计算指定屏幕点到客户端的位置   坐标。

更新

private void Brick_MouseMove(object sender, MouseEventArgs e)
{
    if (isDragging)
    {
        var relativePoint = this.PointToClient(Cursor.Position);
        Brick1.Left = relativePoint.X;
        Brick1.Top = relativePoint.Y;
    }
}
