由直线、曲线创建图形,using System.Drawing.Drawing2D;的应用例子，C#源代码 Point[] points = { new Point(40, 60), new Point(50, 70), new Point(30, 90)}; GraphicsPath path = new GraphicsPath(); path.StartFigure(); // Start the first figure. path.AddArc(175, 50, 50, 50, 0, -180); path.AddLine(100, 0, 250, 20); // First figure is not closed. path.StartFigure(); // Start the second figure. path.AddLine(50, 20, 5, 90); path.AddCurve(points, 3); path.AddLine(50, 150, 150, 180); path.CloseFigure(); // Second figure is closed. e.Graphics.DrawPath(new Pen(Color.FromArgb(255, 255, 0, 0), 2), path); }
