使用GDI绘制形式时闪烁

Question

我现在在Windows窗体中制作Pong游戏，而我渲染图形的方式是每100毫秒从一个任务绘制一个位图，然后使表单无效以强制它重新绘制位图，它按预期工作，除了表单将＆＃34;闪烁＆＃34;每次我重新绘制位图时，有没有办法让它像这样闪烁？

以下是代码：

void IGameView.Draw(Ball ball, Paddle paddle, Paddle paddle2)
{
        //Draw to bitmap
        Graphics gameObj = Graphics.FromImage(gameObjects);
        BackColor = Color.Black; // Clear area to allow redrawing of all game objects
        Pen pen = new Pen(Color.White, 5);
        gameObj.DrawEllipse(pen, new Rectangle(ball.Point, new Size(10, 10))); // Ball
        gameObj.DrawLine(pen, new Point(Size.Width / 2, 0), new Point(Size.Width / 2, Size.Height)); // Net
        gameObj.DrawLine(pen, paddle.Position, new Point(paddle.Position.X, paddle.Position.Y + paddle.Size.Height));
        gameObj.DrawLine(pen, paddle2.Position, new Point(paddle2.Position.X, paddle2.Position.Y + paddle2.Size.Height));
        pen.Dispose();
        gameObj.Dispose();
        Invalidate(); // Invalidate to force redraw of game objects
}

private void GameForm_Paint(object sender, PaintEventArgs e)
{
        using (Graphics graphics = e.Graphics)
        {
            if (InvokeRequired)
            {
                Invoke(new MethodInvoker(() => GameForm_Paint(this, e)));
            } 
            else
            {
                graphics.DrawImage(gameObjects, new Point(0, 0));
            }
        }
}
