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

Question

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

Answer 1

Listing files and folders to model, custom implementation.
This creates a full listing of all files and folders starting from your start directory.

public class DirOrFileModel
    {
        #region Private Members

        private string _name;
        private string _location;
        private EntryType _entryType;

        #endregion

        #region Bindings

        public string Name
        {
            get { return _name; }
            set
            {
                if (value == _name) return;
                _name = value;
            }
        }

        public string Location
        {
            get { return _location; }
            set
            {
                if (value == _location) return;
                _location = value;
            }
        }

        public EntryType EntryType
        {
            get { return _entryType; }
            set
            {
                if (value == _entryType) return;
                _entryType = value;
            }
        }

        public ObservableCollection Entries { get; set; }

        #endregion

        #region Constructor

        public DirOrFileModel()
        {
            Entries = new ObservableCollection();
        }

        #endregion
    }

    public enum EntryType
    {
        Directory = 0,
        File = 1
    }

Method:

 static DirOrFileModel DirSearch(DirOrFileModel startDir)
        {
            var currentDir = startDir;
            try
            {
                foreach (string d in Directory.GetDirectories(currentDir.Location))
                {
                    var newDir = new DirOrFileModel
                    {
                        EntryType = EntryType.Directory,
                        Location = d,
                        Name = Path.GetFileName(d)
                    };
                    currentDir.Entries.Add(newDir);

                    DirSearch(newDir);
                }

                foreach (string f in Directory.GetFiles(currentDir.Location))
                {
                    var newFile = new DirOrFileModel
                    {
                        EntryType = EntryType.File,
                        Location = f,
                        Name = Path.GetFileNameWithoutExtension(f)
                    };
                    currentDir.Entries.Add(newFile);
                }

            }
            catch (Exception excpt)
            {
                Console.WriteLine(excpt.Message);
            }
            return startDir;
        }

Usage:

var dir = new DirOrFileModel
            {
                Name = "C",
                Location = @"C:\",
                EntryType = EntryType.Directory
            };

            dir = DirSearch(dir);
