c# UWP - Convert byte array to InMemoryRandomAccessStream/IRandomAccessStream

I have a problem converting byte array to InMemoryRandomAccessStream or IRandomAccessStream in windows 8?

This is my code, but It doesn't work :

internal static async Task<InMemoryRandomAccessStream> ConvertTo(byte[] arr) 
{
    InMemoryRandomAccessStream randomAccessStream = new InMemoryRandomAccessStream();
    
    Stream stream = randomAccessStream.AsStream();
    
    await stream.WriteAsync(arr, 0, arr.Length);
    await stream.FlushAsync();

    return randomAccessStream;
}

And I created the RandomAccessStreamReference and set the requst datapack in order to share the image to other app

private static async void OnDeferredImageStreamRequestedHandler(DataProviderRequest Request) 
{
    DataProviderDeferral deferral = Request.GetDeferral();
    InMemoryRandomAccessStream stream = await ConvertTo(arr);
    
    RandomAccessStreamReference referenceStream =
            RandomAccessStreamReference.CreateFromStream(stream);
    
    Request.SetData(referenceStream);
}

There's no exception but I can't use the result image byte array

I think there's an error when converting byte[] to InMemoryRandomAccessStream, but it doesn't throw an exception.

Anybody know how to implement it?

if anyone knows how to convert the byte array to IRandomAccessStream, it's also appreciated
