How to get all files in a folder? (recursive)

// How much deep to scan. (of course you can also pass it to the method)
const int HowDeepToScan=4;

public static void ProcessDir(string sourceDir, int recursionLvl)
{
if (recursionLvl<=HowDeepToScan)
{
// Process the list of files found in the directory.
string [] fileEntries = Directory.GetFiles(sourceDir);
foreach(string fileName in fileEntries)
{
// do something with fileName
Console.WriteLine(fileName);
}


// Recurse into subdirectories of this directory.
string [] subdirEntries = Directory.GetDirectories(sourceDir);
foreach(string subdir in subdirEntries)
// Do not iterate through reparse points
if ((File.GetAttributes(subdir) &
FileAttributes.ReparsePoint) !=
FileAttributes.ReparsePoint)

ProcessDir(subdir,recursionLvl+1);
}
}
