Searching a directory and its subdirectories for files, with search pattern(s)

I'm using this in my own app, I thought it might be handy to some of you
you could get a list of all files in a directory and its subdirectories, and you could also apply search pattern(s) when doing the same thing. The documentation comments should be descriptive enough


using System.Collections;
using System.IO;

Code:

---

#region GetFiles (string Path)
/// <summary>
/// Gets all the files in the given folder path and all its subdirectories
/// </summary>
public static string[] GetFiles (string path)
{
        ArrayList files = new ArrayList();
        getFiles (path, ref files);

        return (string[])files.ToArray(typeof(string));
}
private static void getFiles (string path, ref ArrayList files)
{
        try
        {
                string[] folders = Directory.GetDirectories (path);
                for (int i=0;i<folders.Length;i++)                               
                        getFiles (folders[i], ref files);

       
                string[] curFiles = Directory.GetFiles (path);
                files.AddRange (curFiles);
        }
        catch
        {}
}
#endregion
