在 Windows 7 上静音麦克风 [英] Mute microphone on Windows 7

问题描述

我在将 Windows 7 机器上的麦克风静音时遇到问题.但是我发现的所有代码都无法运行，或者它没有执行任何已运行的代码.是否已为使用 C# 代码的 Windows 7 机器完成.我只需要一个开/关解决方案.DDL 文件也适用于 Win x64bit.但我认为我在另一个地方创建了一个错误.

I have an problem with muting the mic on an windows 7 machine. But all the code i have found dosen't run ore it's not doing anything the runned. Have is it done for an Windows 7 machine using C# code. I just need an on/off solution. The DDL file works also with Win x64bit. But i thing that i creates an error another place.

        mixers.Recording.Lines.GetMixerFirstLineByComponentType(
                     MIXERLINE_COMPONENTTYPE.SRC_MICROPHONE).Volume = 0;
            if (!mediaElement1.CheckAccess()) mediaElement1.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, (Action)delegate { mediaElement1.Play(); });


            if (MessageBox.Show("Incoming Call from: " + string.Format(e.RemoteParticipant), "Video Chat Call", MessageBoxButton.YesNo) == MessageBoxResult.Yes)
            {
                mixers.Recording.Lines.GetMixerFirstLineByComponentType(
                             MIXERLINE_COMPONENTTYPE.SRC_MICROPHONE).Volume = 1;
                if (!mediaElement1.CheckAccess()) mediaElement1.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, (Action)delegate { mediaElement1.Stop(); });
                _currentConversation.StartVideo();

            }'

如果在 if (MessageBox.Show("Incoming Call from:" + string.Format(e.RemoteParticipant), "Video Chat Call", MessageBoxButton.YesNo) == MessageBoxResult.Yes)并说{算术运算导致溢出."}

If error occurs at if (MessageBox.Show("Incoming Call from: " + string.Format(e.RemoteParticipant), "Video Chat Call", MessageBoxButton.YesNo) == MessageBoxResult.Yes) and says {"Arithmetic operation resulted in an overflow."}
