本文實例講述了C#實現圖形區域組合操作的方法。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;namespace advanced_drawing{ public partial class Form17 : Form { public Form17() { InitializeComponent(); } private void Form17_Paint(object sender, PaintEventArgs e) { Rectangle regionRect = new Rectangle(20, 20, 100, 100); e.Graphics.DrawRectangle(Pens.Black, regionRect); RectangleF unionRect = new RectangleF(90, 30, 100, 100); e.Graphics.DrawRectangle(Pens.Red, Rectangle.Round(unionRect)); Region myRegion = new Region(regionRect); //myRegion.Union(unionRect); //myRegion.Intersect(unionRect); //myRegion.Exclude(unionRect); //myRegion.Complement(unionRect); myRegion.Xor(unionRect); SolidBrush myBrush = new SolidBrush(Color.Blue); e.Graphics.FillRegion(myBrush, myRegion); } }}希望本文所述對大家的C#程序設計有所幫助。
