本文实例讲述了C#实现图形区域组合操作的方法。分享给大家供大家参考。具体实现方法如下：
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); } } }
希望本文所述对大家的C#程序设计有所帮助。
