Question

How to recursively list all the files in a directory and child directories in C#?

Answer 1

A very simple solution, returns a list of files.

    public static List AllFilesInFolder(string folder)
    {
        var result = new List();

        foreach (string f in Directory.GetFiles(folder))
        {
            result.Add(f);
        }

        foreach (string d in Directory.GetDirectories(folder))
        {
            result.AddRange(AllFilesInFolder(d));
        }

        return result;
    }
