这篇文章主要介绍了winform创建不规则窗体的方法,涉及C#窗体创建的相关参数设置技巧,非常具有实用价值,需要的朋友可以参考下

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();

}

}
