本文實例講述了C#畫筆Pen使用路徑繪制圖形的方法。分享給大家供大家參考。具體實現方法如下：
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Drawing.Drawing2D;namespace WindowsApplication2{ public partial class Form10 : Form { public Form10() { InitializeComponent(); } GraphicsPath get(Rectangle rect, int radius) { int diameter = 2 * radius; Rectangle arcrect = new Rectangle(rect.Location, new Size(diameter, diameter)); GraphicsPath path = new GraphicsPath(); path.AddArc(arcrect, 180, 90); arcrect.X=rect.Right-diameter; path.AddArc(arcrect, 270, 90); arcrect.Y = rect.Bottom - diameter; path.AddArc(arcrect, 0, 90); arcrect.X = rect.Left; path.AddArc(arcrect, 90, 90); path.CloseFigure(); return path; } private void button1_Click(object sender, EventArgs e) { Graphics g = this.CreateGraphics(); int width = this.ClientRectangle.Width; int height = this.ClientRectangle.Height; Rectangle rect = new Rectangle(10, 10, width - 20, height - 20); GraphicsPath path = get(rect, width / 10); g.FillPath(Brushes.Red, path); g.DrawPath(Pens.Yellow, path); } }}希望本文所述對大家的C#程序設計有所幫助。
