Highlight the last created .xls file in a folder

Question

I have a list of .xls files named by their timestamp in a folder. E.g 2013_06_11_13_05_02Report, 2013_06_11_13_08_02Report etc. I have around 100 files and the program is working totally fine.

However, I would like to highlight the last created file in the openFileDialog. How do i do that?

Kindly help...

Try something like this which uses a LINQ query to get the name of the last created file: string folderPath = @c:\myfiles\excel; // or whatever it is var di = new System.IO.DirectoryInfo(folderPath); string lastCreated = di.GetFiles(*.xls).OrderBy(fi => fi.CreationTime).Select(fi => fi.Name).LastOrDefault(); OpenFileDialog ofd = new OpenFileDialog(); ofd.InitialDirectory = folderPath; if (lastCreated != null) ofd.FileName = lastCreated; ofd.Filter = Excel files (*.xls)|*.xls; ofd.RestoreDirectory = true; if (ofd.ShowDialog() == DialogResult.OK) { // blah }
