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

The call to Directory.EnumerateFiles(..) will only set-up the enumerator, because of lazy-evaluation. It's when you execute it, using a foreach that you can raise the exception.

So you need to make sure that the exception is handled at the right place so that the enumeration can continue.

var files = from file in Directory.EnumerateFiles("c:\\",
                           "*.*", SearchOption.AllDirectories)
              select new
              {
                File = file
              };

foreach (var file in files)
{
    try
    {          
        Console.Writeline(file);
    }
    catch (UnauthorizedAccessException uEx)
    {
        Console.WriteLine(uEx.Message);
    }
    catch (PathTooLongException ptlEx)
    {
        Console.WriteLine(ptlEx.Message);
    }
}
