画填充圆:

gra.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;

Brush bush = new SolidBrush(Color.Green);//填充的颜色

画圆圈:

Graphics gra = this.pictureBox1.CreateGraphics();

gra.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;

Pen pen = new Pen(Color.Pink);//画笔颜色                                

gra.DrawEllipse(pen, 250, 10, 100, 100);//画椭圆的方法,x坐标、y坐标、宽、高,如果是100,则半径为50

Graphics gra = this.pictureBox1.CreateGraphics();

Font myFont = new Font("宋体", 60, FontStyle.Bold);
