What's your level in C#?
It's trivial to change the download example from FileStream to MemoryStream
The library is not recommended for beginners.

How to put the picture wrapped inside a MessageMediaPhoto into a MemoryStream? I've tried to use the file_reference property (the only one that is a byte array), then instantiating a new MemoryStream with it, but I'm not getting the picture after processing the memory stream.

I have some code that is partially working:

case MessageMediaPhoto { photo: Photo photo }:
{
    var file = await _client.Upload_GetFile(photo.ToFileLocation(), limit: _client!.FilePartSize) as Upload_File;
    var fileType = file?.type.ToString();
                
    using var stream = new MemoryStream(file!.bytes);
                
    // ...do something with stream
}

However, in some cases, this only gets part of the file, especially if I'm dealing with MessageMediaDocument instead. Upon inspecting the library code, I noticed that the method DownloadFileAsync creates multiple clients for downloading the parts of the file. I've attempted to create a helper method to replicate this behavior with a Stream output, but it's challenging since I don't have access to Client private fields such as _dcSession.

I believe this would be a valuable feature to have, as it allows users to handle files without always having to download them directly, providing the flexibility to manipulate the data in-memory before taking further actions.

It's not. I have thoroughly reviewed all the sections in the Readme, including the examples. Still didn't find a way to accomplish the task that prompted my initial question.
