Why I can't just pass file name to DataReader.Read method?

[Ivanidzo4ka]

ConsoleEnvironment env = new ConsoleEnvironment();
var reader = TextLoader.CreateReader(env, row => (label: row.LoadText(0), image: row.LoadText(1));
var data = reader.Read("file.csv");

will force me to cast file name to MultifileSource. Can I just pass filename if I have only one file?

Also, can we make it accept a list of file names as well?
