how to select files from a list from a particular directory

Question

I know I can use

 Directory.GetFiles(sourceDirectory, pattern);

To get ALL the files with a particular pattern. However, I'm curious as to how would one get only the files wanted (i.e. from a list of some sort) with that same pattern?

i'm not really looking for filters, per say. I'd be looking for something like the following: Directory.GetFiles(sourceDirectory, pattern, listOfFilesToFind); — user1789573, Feb 18 '16 at 17:55

Dont think you can do straight out of GetFiles, you can surely filter them though....

private static string[] GetFiles(string sourceFolder, string filters, System.IO.SearchOption searchOption, List<string> fileNames )
        {
            return System.IO.Directory.GetFiles(sourceFolder, filters, searchOption).Where(fileNames.Contains).ToArray();
        }

I finally found a way to do it w/ GetFiles, but only w/ a Lambda expression using SelectMany – user1789573 Feb 18 '16 at 20:52

string[] filePaths = filesToReturn.SelectMany(f => Directory.GetFiles(sourceDirectory, f)).ToArray();
