I have the followin class, scanning all Subdirectories of a given Directory. I would like to add a new parameter "Maxdepth", so it only scans with a maximum Depth of the given param

e.g.

Dir 1
  Dir 1.1
    Dir 1.1.1
      Dir 1.1.1.1 -> should not be scanned

How can I count the actual depth and go to the next directory?

Actualy I have 3 Arguments:
1. List with Include Paths
2. List with exclude paths
3. Boolean for recursive scan

The 4. Parameter should be the Maxdepth

It seems you need a parameter for current depth.
Or you can count from your structure.

Yes, the parameter for depth is known... the question is how can I handle the depth!

you can use it to decide whether or not going down.
if (recursive && no more than the MaxDepth)
{
      ///.....

To clarify (pardon the terrible pseudo-code):

method([your arguments], int depth)
{
  if (depth > maxDepth) return;
  
  [your code...]
  
  foreach (directory in directories)
  {
    method([your arguments], depth + 1);
  }
}

Probably my Question was not really clear, sorry for that, I'll start another try

The goal with maxdepth is, that the user can give a parameter with the depth, because he's probably not interested in the 3th, 4th etc. level.

So for an Director C:\Windows and a maxlevel of 1 he will scan every subdirectory directly under C:\Windows. With a maxlevel of 2, the scan will go one level deeper (e.g. C:\Windows\Folder1\Subfolder1)

Hope it's more understandable. Sorry for the circumstances...

Ok, I'll clarify the pseudocode a bit more, seems I was too terse (note the currentDepth + 1 !!!):
private static void readDir(DirectoryInfo directory, List<Object> excludePath, Dictionary<String,List<ACL>> lAclSet, bool recursive, int maxDepth, int currentDepth)
{
  if (currentDepth >= maxDepth) return;
 
  //[do stuff....]
 
  if (recursive)
  {
    foreach (DirectoryInfo subDirectory in directory.GetDirectories())
    {
      readDir(subDirectory, excludePath, lAclSet, recursive, maxDepth, currentDepth + 1);
    }
  }
}
