有没有办法将System.IO.Stream转换为Windows.Storage.Streams.IRandomAccessStream？

using System;
using System.IO;
using System.Runtime.InteropServices.WindowsRuntime;
using Windows.Storage.Streams;

public static class StreamExtensions
{
    public static IRandomAccessStream AsRandomAccessStream(this Stream stream)
    {
        if (stream == null)
        {
            throw new ArgumentNullException(nameof(stream));
        }

        if (stream is IRandomAccessStream randomAccessStream)
        {
            return randomAccessStream;
        }

        return new InMemoryRandomAccessStream();
    }
}
