如何在cppwinrt中读取StorageFile中的字节数据？

#include <winrt/Windows.Storage.h>
#include <winrt/Windows.Storage.Streams.h>

using namespace winrt;
using namespace Windows::Storage;

StorageFile file = co_await StorageFile::GetFileFromPathAsync(L"path_to_file");

IRandomAccessStream stream = co_await file.OpenAsync(FileAccessMode::Read);

DataReader reader(stream);
co_await reader.LoadAsync(stream.Size());

std::vector<uint8_t> data(reader.UnconsumedBufferLength());
reader.ReadBytes(data);

#include <winrt/Windows.Storage.h>
#include <winrt/Windows.Storage.Streams.h>

using namespace winrt;
using namespace Windows::Storage;

int main()
{
    winrt::init_apartment();

    StorageFile file = co_await StorageFile::GetFileFromPathAsync(L"path_to_file");
    IRandomAccessStream stream = co_await file.OpenAsync(FileAccessMode::Read);

    DataReader reader(stream);
    co_await reader.LoadAsync(stream.Size());

    std::vector<uint8_t> data(reader.UnconsumedBufferLength());
    reader.ReadBytes(data);

    // 使用读取到的字节数据进行后续处理

    return 0;
}
