程序静音（进程静音）

准备使用微软的EDGE组件，需要静音，按照文档webView.CoreWebView2.IsMuted = true;发现不起作用。。。https://github.com/MicrosoftEdge/WebView2Feedback/issues/2120 又说下个版本修复。等不及了。

这里看到一篇文字：https://stackoverflow.com/questions/70329354/c-sharp-mute-other-application 使用进程静音的方案：

加Nuget包： CSCore

//using CSCore.CoreAudioAPI;
       private  void MuteWebApp() {

            Task.Run(() => {


                foreach (AudioSessionManager2 sessionManager in GetDefaultAudioSessionManager2(DataFlow.Render))
                {
                    using (sessionManager)
                    {
                        using (var sessionEnumerator = sessionManager.GetSessionEnumerator())
                        {
                            foreach (var session in sessionEnumerator)
                            {
                                var simpleVolume = session.QueryInterface<SimpleAudioVolume>();
                                var sessionControl = session.QueryInterface<AudioSessionControl2>();

                                Console.WriteLine((sessionControl.Process.ProcessName, sessionControl.SessionIdentifier));
                                if (Process.GetProcessById(sessionControl.ProcessID).ProcessName.Equals("msedgewebview2"))//chrome
                                {
                                    simpleVolume.IsMuted = true;
                                }
                            }
                        }
                    }
                }
            });





        }


        private static IEnumerable<AudioSessionManager2> GetDefaultAudioSessionManager2(DataFlow dataFlow)
        {
            var enumerator = new MMDeviceEnumerator();
            var devices = enumerator.EnumAudioEndpoints(dataFlow, DeviceState.Active);
            foreach (var device in devices)
            {
                Console.WriteLine("Device: " + device.FriendlyName);
                var sessionManager = AudioSessionManager2.FromMMDevice(device);
                yield return sessionManager;
            }
        }
