本文实例讲述了winform创建不规则窗体的方法。分享给大家供大家参考。具体如下：
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using Microsoft.Win32; using System.Drawing.Drawing2D; using System.IO; namespace WindowsApplication2 { public partial class Form3 : Form { public Form3() { InitializeComponent(); this.FormBorderStyle = FormBorderStyle.None; ColorConverter colorconvert = new ColorConverter(); this.BackColor = (Color)colorconvert.ConvertFromString("window"); this.TransparencyKey = (Color)colorconvert.ConvertFromString("window"); } private void button1_Click(object sender, EventArgs e) { this.Close(); } protected override void OnPaint(PaintEventArgs e) { Graphics g = e.Graphics; Rectangle mainRect = new Rectangle(0, 0, 695, 278); Region mainRegion = new Region(mainRect); e.Graphics.SetClip(mainRegion, CombineMode.Replace); //设置窗体的外观形式 Point point1 = new Point(0, 32); Point point2 = new Point(9, 20); Point point3 = new Point(21, 13); Point point4 = new Point(34, 9); // 创建一个以点为元素的数组 Point[] curvePoints = { point1, point2, point3, point4 }; // 创建一个GraphicsPath 对象并添加一条曲线 GraphicsPath gPath = new GraphicsPath(); gPath.AddCurve(curvePoints, 0, 3, 0.8f); gPath.AddLine(36, 9, 378, 9); point1.X = 378; point1.Y = 9; point2.X = 387; point2.Y = 5; point3.X = 394; point3.Y = 0; Point[] curvePoints2 = { point1, point2, point3 }; gPath.AddCurve(curvePoints2, 0, 2, 0.8f); gPath.AddLine(394, 0, 0, 0); Region rg = new Region(gPath); e.Graphics.ExcludeClip(rg); //可以为任意图片 string str = Directory.GetCurrentDirectory() + "2.png"; Image img = Image.FromFile(str); e.Graphics.DrawImage(img, 0, 0, 695, 278); // 重设剪切好的区域 e.Graphics.ResetClip(); } } }
希望本文所述对大家的C#程序设计有所帮助。
