无法将字节数组从 UWP C# 组件传递到 WinRT C++成分

我正在尝试在WinRT C ++组件中渲染图像数据，因此我将一个字节数组从UWP组件传递给WinRT组件。但是IDL不支持字节*

streamSamplepool.cpp

void StreamSamplePool::HandleFrameData(BYTE* frameData)
{
}

streamSamplepool.h

void HandleFrameData(BYTE* pData);

这是没有任何问题的编译，但是问题是我们想在IDL文件中定义此问题时不支持指针，另外也尝试使用无符号字符的Ivector/数组，但这似乎也不支持IDL文件中的支持。如何将字节数组从UWP组件传递到WinRT组件？从C＃传递字节数组的任何示例段，IDL文件中的定义都会有所帮助

原文

I'm trying to render image data in the WinRT C++ component, so I'm passing a byte array from the UWP component to the WinRT component.
But IDL Doesn't support Byte*

StreamSamplePool.cpp

void StreamSamplePool::HandleFrameData(BYTE* frameData)
{
}

StreamSamplePool.h

void HandleFrameData(BYTE* pData);

This is compiling without any issues but the problem is when we want to define this in the IDL file, IDL doesn't support pointers, alternatively tried using IVector/Array of unsigned char as well but that too doesn't seem to be supported in the IDL file. How do I pass the byte array from UWP Component to the WinRT Component?
Any sample snippet of passing byte array from C# and definition in IDL file would be helpful
