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。
