  • Winform 窗体实现圆角展示

    触发窗体的Resize事件,如下所示:

     #region 界面实现圆角
            private void LoginForm_Resize(object sender, EventArgs e)
            {
                if (this.WindowState == FormWindowState.Normal)
                {
                    SetWindowRegion();
                }
                else
                {
                    this.Region = null;
                }
            }
    
            public void SetWindowRegion()
            {
                System.Drawing.Drawing2D.GraphicsPath FormPath;
                FormPath = new System.Drawing.Drawing2D.GraphicsPath();
                Rectangle rect = new Rectangle(0, 0, this.Width, this.Height);
                FormPath = GetRoundedRectPath(rect, 10);//10代表圆角角度大小
                this.Region = new Region(FormPath);
            }
    
            /// <summary>
            /// 
            /// </summary>
            /// <param name="rect">窗体大小</param>
            /// <param name="radius">圆角大小</param>
            /// <returns></returns>
            private GraphicsPath GetRoundedRectPath(Rectangle rect, int radius)
            {
                int diameter = radius;
                Rectangle arcRect = new Rectangle(rect.Location, new Size(diameter, diameter));
                GraphicsPath path = new GraphicsPath();
    
                path.AddArc(arcRect, 180, 90);//左上角
    
                arcRect.X = rect.Right - diameter;//右上角
                path.AddArc(arcRect, 270, 90);
    
                arcRect.Y = rect.Bottom - diameter;// 右下角
                path.AddArc(arcRect, 0, 90);
    
                arcRect.X = rect.Left;// 左下角
                path.AddArc(arcRect, 90, 90);
                path.CloseFigure();
                return path;
            }
    
            #endregion
