Question

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

Answer 1

A simple and clean solution

/// 

/// Scans a folder and all of its subfolders recursively, and updates the List of files
/// 
/// Full path of the folder
/// The list, where the output is expected
internal static void EnumerateFiles(string sFullPath, List fileInfoList)
{
    try
    {
        DirectoryInfo di = new DirectoryInfo(sFullPath);
        FileInfo[] files = di.GetFiles();

        foreach (FileInfo file in files)
            fileInfoList.Add(file);

        //Scan recursively
        DirectoryInfo[] dirs = di.GetDirectories();
        if (dirs == null || dirs.Length < 1)
            return;
        foreach (DirectoryInfo dir in dirs)
            EnumerateFiles(dir.FullName, fileInfoList);

    }
    catch (Exception ex)
    {
        Logger.Write("Exception in Helper.EnumerateFiles", ex);
    }
}
