改变窗体

this.SizeChanged += Form1_SizeChanged;
...
private void Form1_SizeChanged(object sender, EventArgs e){
//操作代码
}

NotifyIcon1鼠标左右键

private void NotifyIcon1_MouseClick(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Right)
            {
               //右键
            }

            if (e.Button == MouseButtons.Left)
            {
                //左键
            }

        }

禁止CefSharp ChromiumWebBrowser新窗口打开

public class CefLifeSpanHandler : ILifeSpanHandler
        {
            public CefLifeSpanHandler()
            {

            }

            public bool DoClose(IWebBrowser browserControl, IBrowser browser)
            {
                if (browser.IsDisposed || browser.IsPopup)
                {
                    return false;
                }

                return true;
            }

            public void OnAfterCreated(IWebBrowser browserControl, IBrowser browser)
            {

            }

            public void OnBeforeClose(IWebBrowser browserControl, IBrowser browser)
            {
            }

            // 阻止打开新的窗体
            public bool OnBeforePopup(IWebBrowser browserControl, IBrowser browser, IFrame frame, string targetUrl, string targetFrameName, WindowOpenDisposition targetDisposition, bool userGesture, IPopupFeatures popupFeatures, IWindowInfo windowInfo, IBrowserSettings browserSettings, ref bool noJavascriptAccess, out IWebBrowser newBrowser)
            {
                newBrowser = null;
                var chromiumWebBrowser = (ChromiumWebBrowser)browserControl;
                chromiumWebBrowser.Load(targetUrl);
                return true;
            }
        }

控件设置

 public void InitializeChromium()
        {
            CefSettings settings = new CefSettings() { IgnoreCertificateErrors = true };

            Cef.Initialize(settings);
            web.LifeSpanHandler = new CefLifeSpanHandler();
            web.BrowserSettings = new BrowserSettings()
            {
                WebGl = CefState.Enabled,
                ImageLoading = CefState.Enabled,
                RemoteFonts = CefState.Enabled,
                AcceptLanguageList = "zh-CN"
            };
        }

浏览器缓存配置

 var settings = new CefSettings()
            {
                Locale = "zh-CN",
                CachePath = Directory.GetCurrentDirectory() + @"\Cache",
                IgnoreCertificateErrors = true
            };

            settings.CefCommandLineArgs.Add("proxy-auto-detect", "0");
            settings.CefCommandLineArgs.Add("no-proxy-server", "1");

            /*初始化配置*/
            Cef.Initialize(settings);

禁止程序多开,Program.cs

static class Program
    {
        static readonly Mutex  mutex = new Mutex(true, "MyMutex");
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        
        static void Main()
        {

            if (mutex.WaitOne(TimeSpan.Zero, true))
            {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);
                Application.Run(new Form1());
                mutex.ReleaseMutex();
            }
            else
            {
                MessageBox.Show("程序已经在运行中!","提示");
            }
        }

    }

圆角:控件

class DesignForm
    {
        public void Type(Control sender, int p_1, double p_2)
        {
            GraphicsPath oPath = new GraphicsPath();
            oPath.AddClosedCurve(new Point[] { new Point(0, sender.Height / p_1), new Point(sender.Width / p_1, 0), new Point(sender.Width - sender.Width / p_1, 0), new Point(sender.Width, sender.Height / p_1), new Point(sender.Width, sender.Height - sender.Height / p_1), new Point(sender.Width - sender.Width / p_1, sender.Height), new Point(sender.Width / p_1, sender.Height), new Point(0, sender.Height - sender.Height / p_1) }, (float)p_2);
            sender.Region = new Region(oPath);
        }

    }

调用方式:

 public partial class Form1 : Form
    {
        readonly DesignForm DDesignF = new DesignForm();
//...
DDesignF.Type(控件名, 15, 0.2);

控件圆形

public void region(Control sender)
        {
            
            GraphicsPath gp = new GraphicsPath();
            gp.AddEllipse(sender.ClientRectangle);
            Region region = new Region(gp);
            sender.Region = region;
            gp.Dispose();
            region.Dispose();
        }

调用:

DDesignF.region(QRClose);

交互,点击浏览器上元素

Pweb.EvaluateScriptAsync("document.querySelector('.play-pause').click()");
