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

[MrPolite]

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;

#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

#region GetFiles (string path, string[] searchPatterns, bool includeSubFolders) +1 overload
/// <summary>
/// Gets all the files in the given folder path and all its subdirectories.

public static string[] GetFiles(string path, string[] searchPatterns, bool includeSubFolders)
{
	ArrayList files = new ArrayList();
	if (includeSubFolders)
	{
		getFiles (path, searchPatterns, ref files);
	}
	else
	{
		try
		{
			for (int i=0; i<searchPatterns.Length; i++)
			{
				string[] curFiles = Directory.GetFiles (path, searchPatterns[i]);
				files.AddRange (curFiles);
