Sorting the result of Directory.GetFiles in C#
Very easy with LINQ.
To sort by name,
var sorted = Directory.GetFiles(".").OrderBy(f => f);
To sort by size,
var sorted = Directory.GetFiles(".").OrderBy(f => new FileInfo(f).Length);
To order by date: (returns an enumerable of FileInfo):
Directory.GetFiles(folder, "*.dll").Select(fn => new FileInfo(fn)).
OrderBy(f => f.Length);
or, to order by name:
Directory.GetFiles(folder, "*.dll").Select(fn => new FileInfo(fn)).
OrderBy(f => f.Name);
Making FileInfo
instances isn't necessary for ordering by file name, but if you want to apply different sorting methods on the fly it's better to have your array of FileInfo
objects in place and then just OrderBy
them by Length
or Name
property, hence this implementation. Also, it looks like you are going to create FileInfo
anyway, so it's better to have a collection of FileInfo
objects either case.
Sorry I didn't get it right the first time, should've read the question and the docs more carefully.
You can use LINQ if you like, on a FileInfo object:
var orderedFiles = Directory.GetFiles("").Select(f=> new FileInfo(f)).OrderBy(f=> f.CreationTime)
