Get list of all files in a directory?

Question

How can I get a list of all files in a given local directory (standalone player)?

For instance, I have a "characters" folder that goes inside my app directory, and I would like to be able to get a list of all XML (or whatever) files in that folder at runtime to parse through.

Preferably in Javascript but C# is fine.

Use DirectoryInfo:

 import System.IO;
 ...
 var info = new DirectoryInfo(path);
 var fileInfo = info.GetFiles();
 for (file in fileInfo) print (file);

@headkit: replace "`import`" with "`using`", and "`for (file`" with "`foreach (FileInfo file`".

In C#, you can also simplify things greatly like so:

 foreach (string file in System.IO.Directory.GetFiles(path))
 { }

^ Note that this doesn't require 'using System . IO'

It's strange the Unity's $$anonymous$$ono implementation supports GetFiles but not the IEnumerable methods like EnumerateFiles.

The Correct way (Calls the GetFiles() Method only once):

  string [] files = System.IO.Directory.GetFiles(path);
     foreach (string file in files)
     {
          //Do work on the files here
     }

The Incorrect way(Calls the GetFiles() Method every iteration):

 foreach (string file in System.IO.Directory.GetFiles(path))
 {
      //Do work on the files here
 }

Laziness leads to bugs.

@NOAA_Julien: You can do that in JS too, but I broke it down into steps to make it more clear. That's not necessarily simplified; you might very well want to keep the references in variables like I showed, depending on what you're doing elsewhere. It's also pretty likely you're doing other file operations, so importing the System.IO namespace avoids having to append that to every file command you do.

In C# you can do it with:

 using System.IO;
 DirectoryInfo dir = new DirectoryInfo(myPath);
 FileInfo[] info = dir.GetFiles("*.*");
 foreach (FileInfo f in info) 
 { ... }

If you have a specific file you want to, you can use *.extension like this

directory.GetFiles("*.asset");

ANSWER UPDAtE 2015 ERICS ANSWER IS NOT CURRENT SYNTAX>..

YES THIS IS CURRENT ANSWER YOU SAW THAT HAHA

 function Start () {
 GetFiles();

 // var filePaths : String[] = Directory.GetFiles(info);
 // for (file in filePaths) print (file);


 }

or

 function GetFiles(){

 var info :String = Application.dataPath + "/AudioWave/";
  var fileInfo =Directory.GetFiles(info);
  for (file in fileInfo) print (file);


   }

 System.IO.Path.GetFileName(fullPath)

to get the name of only the file from string.. fullpath string.

to get the files by type do this i.e. text

var fileInfo =Directory.GetFiles(info,"*.txt");
