									using System.Collections.Generic;

									using System.ComponentModel;

									using System.Data;

									using System.Drawing;

									using System.Text;

									using System.Windows.Forms;

									 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();

									  }

									 }
