C# Windows Media Capture-402587628错误“；找不到与此错误代码关联的文本。”；

尝试初始化Async mediaCapture时，第二个“catch”语句中出现问题

---

如果没有提供任何错误详细信息，我如何检查出了什么问题？

这段代码对我来说运行正常。你是否在应用程序清单中设置了麦克风和网络摄像头功能？是的，我设置了。在Windows Phone 10上使用摄像头是否有任何问题？在PC机上它工作得很好…这个代码对我来说很好。你是否在应用程序清单中设置了麦克风和网络摄像头功能？是的，我设置了。在Windows Phone 10上使用摄像头是否有任何问题？在PC上，它工作得很好。。。
