PSA: Stop using Streams and Reader/Writers to Convert Strings/ByteArrays

using (var memory = new MemoryStream())
{
    using (StreamWriter writer = new StreamWriter(memory, Encoding.ASCII))
    {
        foreach (var lineData in dataLines)
        {
            writer.WriteLine(lineData);
        }

        writer.Flush();
        return memory.GetBuffer();
    }
}

return Encoding.ASCII.GetBytes(lineData.Join("\n\r"));
