A simple recursive function to get all files in all sub-dirs of a folder

The below code is in .NET C#public ArrayList

GetAllFiles(string directory)

{

ArrayList totalFilesList = new ArrayList(10);

string[] files = Directory.GetFiles(directory);//add all files in that current folder.totalFilesList.AddRange(files);//Check if the current directory has sub-directories string [] subDirs = Directory.GetDirectories(directory);

if(subDirs.Length > 0)

{

//now look for all files in current folder's sub-dir's. foreach(string subDir in subDirs)

{

ArrayList tempArrayList = GetAllFiles(subDir);

totalFilesList.AddRange(tempArrayList);

}

}

return totalFilesList;

}
