enumerate

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/recover from that and continuing enumerate the rest of the files? try { var files = from file in Directory.EnumerateFiles("c:\\", "*.*", SearchOption.AllDirectories) select new { File = file }; Console.WriteLine(files.Count().ToString()); } catch (UnauthorizedAccessException uEx) { Console.WriteLine(uEx.Message); } catch (PathTooLongException ptlEx) { Console.WriteLine(ptlEx.Message); } I did found a solution to this. By using a stack

In Python I can write: for i, element in enumerate(my_list): print i # the index, starting from 0 print element # the list-element How can I write this in Kotlin? There is a forEachIndexed function in the standard library: myList.forEachIndexed { i, element -> println(i) println(element) } See @s1m0nw1's answer as well, withIndex is also a really nice way to iterate through an Iterable . Iterations in Kotlin: Some Alternatives Like already said, forEachIndexed is a good way to iterate. Alternative 1: the extension withIndex , defined for Iterable types, can be used in for -each: val ints =

Is there a way, in WPF, to enumerate through all files within a specific embedded resource directory? That is, a directory of items all having a "Build Action" set to "Resource". Charles The resources are compiled into a resource stream named YourAssemblyName.g.resources . So, we load up this stream which appears to be a dictionary where the key is the resource name and the value is the resource data. We are interested in the resource name as that is (usually) the original folder and file name for the resource. We then filter out those keys that begin with the folder we are interested in.

I've got some code like this: letters = [('a', 'A'), ('b', 'B')] i = 0 for (lowercase, uppercase) in letters: print "Letter #%d is %s/%s" % (i, lowercase, uppercase) i += 1 I've been told that there's an enumerate() function that can take care of the "i" variable for me: for i, l in enumerate(['a', 'b', 'c']): print "%d: %s" % (i, l) However, I can't figure out how to combine the two: How do I use enumerate when the list in question is made of tuples? Do i have to do this? letters = [('a', 'A'), ('b', 'B')] for i, tuple in enumerate(letters): (lowercase, uppercase) = tuple print "Letter #%d is
