I am trying to get a list of all files in a folder from C#. Easy enough:
Directory.GetFiles(folder)
But I need the result sorted alphabetically-reversed, as they are all numbers and I need to know the highest number in the directory. Of course I could grab them into an array/list object and then do a sort, but I was wondering if there is some filter/parameter instead?
They are all named with leading zeros. Like:
00000000001.log
00000000002.log
00000000003.log
00000000004.log
..
00000463245.log
00000853221.log
00024323767.log
Whats the easiest way? I dont need to get the other files, just the "biggest/latest" number.
var files = Directory.EnumerateFiles(folder)
.OrderByDescending(filename => filename);
(The EnumerateFiles
method is new in .NET 4, you can still use GetFiles
if you're using an earlier version)
EDIT: actually you don't need to sort the file names, if you use the MaxBy
method defined in MoreLinq:
var lastFile = Directory.EnumerateFiles(folder).MaxBy(filename => filename);
