Question Best way for get last modified file in a folder

[Andrea]

Hello everyone, I'm new in this forum so if I'm wrong something please tell me. I'm trying to get the last modified file in a folder. I know is possible with GetLastWriteTime and DateTime.Compare(), but I'm searching for a more efficient way, if it is possible.

I hope someone can help me.

var folder = new DirectoryInfo("folder path here");
var files = folder.EnumerateFiles();
var lastModifiedFile = files.OrderBy(fi => fi.LastWriteTime).Last();
var filePath = lastModifiedFile.FullName;

or, if you want it all in one line of code:

var filePath = new DirectoryInfo("folder path here").EnumerateFiles()
                                                    .OrderBy(fi => fi.LastWriteTime)
                                                    .Last()
                                                    .FullName;

Note that OrderByDescending and First would have the same effect.
