Is there a way of recover from an Exception in Directory.EnumerateFiles?

Question

In .NET 4, there\'s this Directory.EnumerateFiles() method with recursion that seems handy.
However, if an Exception occurs within a recursion, how can I continue/recove

Answer 1

I did found a solution to this. By using a stack to push the enumeration results, one can indeed handle the exceptions. Here's a code snippet: (inspired by this article)

List results = new List();
string start = "c:\\";
results.Add(start);
Stack stack = new Stack();

do
{
  try
  {
    var dirs = from dir in Directory.EnumerateDirectories(
                     start, "*.*", SearchOption.TopDirectoryOnly)
                select dir;

    Array.ForEach(dirs.ToArray(), stack.Push);
    start = stack.Pop();
    results.Add(start);
  }
  catch (UnauthorizedAccessException ex)
  {
    Console.WriteLine(ex.Message);
    start = stack.Pop();
    results.Add(start);
  }

} while (stack.Count != 0);

foreach (string file in results)
{
  Console.WriteLine(file);
}
