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

Here's my angle on it, based on Hernaldo's, if you need to find files with names of a certain pattern, such as XML files that somewhere in their name contain a particular string:

// call this like so: GetXMLFiles("Platypus", "C:\\");
public static List GetXMLFiles(string fileType, string dir)
{
    string dirName = dir; 
    var fileNames = new List();
    try
    {
        foreach (string f in Directory.GetFiles(dirName))
        {
            if ((f.Contains(fileType)) && (f.Contains(".XML")))
            {
                fileNames.Add(f);
            }
        }
        foreach (string d in Directory.GetDirectories(dirName))
        {
            GetXMLFiles(fileType, d);
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
    return fileNames;
}
