代码:
private void button1_Click(object sender, System.EventArgs e)
  {
   Graphics g = this.CreateGraphics();
   g.Clear(Color.White);
   //g.InterpolationMode = InterpolationMode.HighQualityBicubic;
   g.CompositingQuality = CompositingQuality.HighQuality;
   g.SmoothingMode = SmoothingMode.HighQuality;
           
   int radius = 200;
   CircularTextualLayout ctl = new CircularTextualLayout();
   ctl.Radius = radius;
   Point location = new Point(50, 20);
   //ctl.CenterPoint = new Point(location.X + radius, location.Y + radius);
   ctl.TextDrawing = "方正姚体方正姚体方正姚体方正姚体";

   float arcAngle = 270;
   ctl.ArcAngle = arcAngle;
   ctl.AngleStart = -arcAngle/2 + arcAngle/2/ctl.TextDrawing.Length;
   ctl.TextFontInner = new Font("方正姚体", radius/3.2f);
   ctl.RatioX = 0.6f;
   ctl.BorderWidth = (int)(ctl.Radius / 40);
   //ctl.IsBold = false;
   ctl.Location = location;
   ctl.WordsColor = Color.FromArgb(250, Color.Red);
   ctl.BorderColor = Color.FromArgb(250, Color.Red);
   ctl.RectColor = Color.FromArgb(250, Color.Red);
   ctl.Draw(g);

   g.Dispose();
  }
