MediaFrameReference.Properties 中的__ComObject value Managed 对象类型怎么知道? RRS feed

  • 问题

  • 开发UWP Camera App,从MediaFrameReference.Properties 获取到{2EBE23A8-FAF5-444A-A6A2-EB810880AB5D} 对应的值是__ComObject 对象, 请问该对象的Managed 接口是什么?有什么办法能获取对象类型吗?

    {2EBE23A8-FAF5-444A-A6A2-EB810880AB5D}GUID 对应的是MFSampleExtension_CaptureMetadata  

    Type: IUnknown (IMFAttributes)
    This is the IMFAttributes store for all the metadata related to the capture.

  • Hi Henry,

    有关UWP的问题,我建议你可以到下面这个地方进行询问。

    uwp-Microsoft Q&A

    .net framework论坛只讨论与.net framework相关的技术和知识。

    Best Regards,
