How to get filename within folders in WEB API server

Question

I have a directory Archive/Uploads

And I would like to list all the files, within this directory I have N folders.

what I’ve got so far is here.

string path = HttpContext.Current.Server.MapPath("~//Arquivos//Uploads");
            string[] files = System.IO.Directory.GetFiles(path);

Answer 1

Utilize Enumeratefiles to get the files from a given directory by configuring the third parameter System.IO.SearchOption.AllDirectories so that the search is done in all directories.

string path = HttpContext.Current.Server.MapPath("~//Arquivos//Uploads");
IEnumerable<string> files = System.IO.Directory.EnumerateFiles(path,
                                      "*.*",
                                       System.IO.SearchOption.AllDirectories);

^{Observing: System.IO.Directory.GetFiles can also be used in the same way having also 3 pan the same definition of System.IO.SearchOption.AllDirectories.}

System.IO.Directory.Getfiles(path, "*.*", System.IO.SearchOption.AllDirectories);

Using Linq can work better this information and get only the name of the files:

var result = System.IO.Directory.EnumerateFiles(path, 
                      "*.*", 
                      System.IO.SearchOption.AllDirectories)
                .Select(c => 
                       c.Split(new string[] { "\\" }, StringSplitOptions.None).Last())
                .ToArray();
