自定义淡入淡出提示窗口

首先创建一个自定义提示窗体 FadeMessageForm

public class FadeMessageForm : Form
{
    public FadeMessageForm(string message)
    {
        FormBorderStyle = FormBorderStyle.None;
        StartPosition = FormStartPosition.Manual;
        Location = new Point(Screen.PrimaryScreen.WorkingArea.Width - Width - 20, 
                           Screen.PrimaryScreen.WorkingArea.Height - Height - 20);
        Size = new Size(300, 100);
        BackColor = Color.LightGreen;
        
        var label = new Label
        {
            Text = message,
            Dock = DockStyle.Fill,
            TextAlign = ContentAlignment.MiddleCenter,
            Font = new Font("微软雅黑", 10)
        };
        
        Controls.Add(label);
        
        // 设置淡入淡出效果
        Opacity = 0;
        Timer fadeInTimer = new Timer { Interval = 50 };
        fadeInTimer.Tick += (s, e) => {
            if ((Opacity += 0.1) >= 1) 
            {
                fadeInTimer.Stop();
                
                // 3秒后开始淡出
                Timer fadeOutTimer = new Timer { Interval = 3000 };
                fadeOutTimer.Tick += (s2, e2) => {
                    if ((Opacity -= 0.1) <= 0)
                    {
                        fadeOutTimer.Stop();
                        Close();
                    }
                };
                fadeOutTimer.Start();
            }
        };
        fadeInTimer.Start();
    }
}

1. 然后在你的代码中使用：

   if (!string.IsNullOrEmpty(qrCodeData))
   {
       Clipboard.SetText(qrCodeData);
       new FadeMessageForm("二维码链接已复制到剪贴板").Show();
   }
   

   完整代码

    public class FadeMessageForm : Form
    {
        //添加阴影效果（使窗体看起来更立体）：
        protected override CreateParams CreateParams
        {
            get
            {
                const int CS_DROPSHADOW = 0x00020000;
                CreateParams cp = base.CreateParams;
                cp.ClassStyle |= CS_DROPSHADOW;
                return cp;
            }
        }
        //圆角窗体设计
        protected override void OnPaint(PaintEventArgs e)
        {
            base.OnPaint(e);
            using (var path = new GraphicsPath())
            {
                path.AddArc(0, 0, 20, 20, 180, 90);
                path.AddArc(Width - 20, 0, 20, 20, 270, 90);
                path.AddArc(Width - 20, Height - 20, 20, 20, 0, 90);
                path.AddArc(0, Height - 20, 20, 20, 90, 90);
                path.CloseFigure();
                Region = new Region(path);
            }
        }
        //添加鼠标点击关闭功能：
        protected override void OnClick(EventArgs e)
        {
            base.OnClick(e);
            Close();
        }

        protected override void OnKeyDown(KeyEventArgs e)
        {
            base.OnKeyDown(e);
            if (e.KeyCode == Keys.Escape)
            {
                Close();
            }
        }
        public FadeMessageForm(string message)
        {
            FormBorderStyle = FormBorderStyle.None;
            StartPosition = FormStartPosition.Manual;
            //Location = new Point(Screen.PrimaryScreen.WorkingArea.Width - Width - 20,
            //                   Screen.PrimaryScreen.WorkingArea.Height - Height - 20);
            // 替换原来的Location设置
            Screen targetScreen = Screen.FromPoint(Cursor.Position); // 或指定其他屏幕
            Location = new Point(targetScreen.WorkingArea.Right - Width - 20,
                               targetScreen.WorkingArea.Bottom - Height - 20); //多显示器支持：
            Size = new Size(170, 50);

            BackColor = Color.White;
            // 设置为置顶窗体
            TopMost = true;  // 新增这行代码使窗体置顶
            var label = new Label

            Timer fadeInTimer = new Timer { Interval = 16 }; // 约60FPS (1000ms/60≈16ms)
            double fadeStep = 0.05; // 减小每次变化的步长

            fadeInTimer.Tick += (s, e) =>
            {
                if ((Opacity += fadeStep) >= 1)

                    fadeInTimer.Stop();

                    // 2秒后开始淡出
                    Timer fadeOutTimer = new Timer { Interval = 16 }; // 同样60FPS
                    fadeOutTimer.Tick += (s2, e2) =>
                    {
                        if ((Opacity -= fadeStep) <= 0)
