本文实例讲述了C#非矩形窗体实现方法。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;
using System.Drawing.Drawing2D;
namespace WindowsApplication1
{
public partial class Form3 : Form
{
Point downPoint = Point.Empty;
public Form3()
{
InitializeComponent();
}
void Set()
{
Rectangle rect = this.ClientRectangle;
using (GraphicsPath path = new GraphicsPath())
{
path.AddEllipse(rect);
this.Region = new Region(path);
}
}
private void Form3_Load(object sender, EventArgs e)
{
Set();
}
private void Form3_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button != MouseButtons.Left) return;
downPoint = new Point(e.X, e.Y);
}
private void Form3_MouseMove(object sender, MouseEventArgs e)
{
if (downPoint == Point.Empty) return;
Point location = new Point(this.Left + e.X - downPoint.X, this.Top + e.Y - downPoint.Y);
this.Location = location;
}
private void Form3_MouseUp(object sender, MouseEventArgs e)
{
if (e.Button != MouseButtons.Left) return;
downPoint = Point.Empty;
}
}
}

希望本文所述对大家的C#程序设计有所帮助。
