c#之从 CSCore audiostream 获取进程名称或 ID

我已经使用 CSCore 库从我的程序中过滤了所有音频流。它工作正常，但我不知道哪个流属于哪个进程。 有没有办法获取每个流的 processId 或 processname？

我的代码:

public class Audio 
{ 
    public static void start(ListBox device, ListBox process) 
    { 
        using (var sessionManager = GetDefaultAudioSessionManager2(DataFlow.Render)) 
        { 
 
            using (var sessionEnumerator = sessionManager.GetSessionEnumerator()) 
            { 
 
                foreach (var session in sessionEnumerator) 
                { 
                    using (var audioMeterInformation = session.QueryInterface<AudioMeterInformation>()) 
                    { 
                        device.Items.Add(audioMeterInformation.GetPeakValue()); 
 
                        process.Items.Add("here I need the processname or ID"); 
                    } 
                } 
            } 
        } 
 
 
    } 
 
    private static AudioSessionManager2 GetDefaultAudioSessionManager2(DataFlow dataFlow) 
    { 
        using (var enumerator = new MMDeviceEnumerator()) 
        { 
            using (var device = enumerator.GetDefaultAudioEndpoint(dataFlow, Role.Multimedia)) 
            { 
                var sessionManager = AudioSessionManager2.FromMMDevice(device); 
                return sessionManager; 
            } 
        } 
    } 
} 

非常感谢!

请您参考如下方法:

您必须查询 AudioSessionControl2 对象的实例:

public class Audio 
{ 
    public static void start(ListBox device, ListBox process) 
    { 
        using (var sessionManager = GetDefaultAudioSessionManager2(DataFlow.Render)) 
        { 
 
            using (var sessionEnumerator = sessionManager.GetSessionEnumerator()) 
            { 
                foreach (var session in sessionEnumerator) 
                { 
                    using (var audioMeterInformation = session.QueryInterface<AudioMeterInformation>()) 
                    using(var session2 = session.QueryInterface<AudioSessionControl2>()) 
                    { 
                        device.Items.Add(audioMeterInformation.GetPeakValue()); 
                        var processID = session2.ProcessID; 
                        process.Items.Add("here I need the processname or ID"); 
                    } 
                } 
            } 
        } 
 
 
    } 
 
    private static AudioSessionManager2 GetDefaultAudioSessionManager2(DataFlow dataFlow) 
    { 
        using (var enumerator = new MMDeviceEnumerator()) 
        { 
            using (var device = enumerator.GetDefaultAudioEndpoint(dataFlow, Role.Multimedia)) 
            { 
                var sessionManager = AudioSessionManager2.FromMMDevice(device); 
                return sessionManager; 
            } 
        } 
    } 
}
