加载窗口时的C＃绘制

Question

I want to draw some ellipses when the window is loaded without clicking anything, how can I do it? My code is the following :

        int kerX = random.Next(10,281);
        int kerY = random.Next(10,281);
        mrPainter.FillEllipse(Brushes.Black, kerX + 10, kerY + 10, 20, 20);
        mrPainter.FillEllipse(blue,65,65,20,20);
        mrPainter.FillEllipse(red, 205, 65, 20, 20);
        mrPainter.FillEllipse(yellow, 135, 215, 20, 20);

假设您正在使用WinForms，只需将代码插入主窗体的FormLoaded事件中。
