C# list file in directory issue

Question

I am using VSTS 2008 + C# + .Net 3.0. I want to enumerate all files in a directory by creation time, i.e. files created more recently will be enumarate at first, older files will be enumerated at last. Any ideas how to implment this?

Answer 1

Something like that

System.IO.FileInfo[] array = new System.IO.DirectoryInfo("directory_path").GetFiles();
Array.Sort(array, delegate(System.IO.FileInfo f1, System.IO.FileInfo f2)
            {
                return f2.CreationTimeUtc.CompareTo(f1.CreationTimeUtc);
            });

Answer 2

I would probably use LINQ and a list... something like this should work:

 DirectoryInfo di = new DirectoryInfo("YourPath");
 List<FileInfo> files = di.GetFiles().OrderBy(f => f.CreationTime).ToList();

 foreach (FileInfo file in files)
        {
            //do something
        }
