how to do infinitive loop for finding all sub folders / files C#

Question

ok I've managed to do a loop of 5 Subfolders and all files in them

but I wander how do I create a loop that loops it self and knows he's own loop changes a bit each time it loops it self of it has finished it's loop

I know it's a bit complicated - how do I make this code going infinitive (or untill last subfolder found)

     public List`<`TextureC> texturec ;
     
     public string[] dirPaths;
     public string[] dirPaths1;
     public string[] dirPaths2;
     public string[] dirPaths3;
     public string[] dirPaths4;
     public string[] dirPaths5;

     public string[] filePaths;
     public string[] filePaths1;
     public string[] filePaths2;
     public string[] filePaths3;
     public string[] filePaths4;
     public string[] filePaths5;


     void ResizeTextures(){    
         
         
         
         dirPaths = Directory.GetDirectories(Application.dataPath + "/Resources/Textures/");
         for (int di = 0; di < dirPaths.Length ; di++){
             filePaths = Directory.GetFiles(dirPaths[di]);
             for (int fi = 0; fi < filePaths.Length; fi++){
                 texturec.Add (new TextureC (filePaths[fi]));
             }
             
             dirPaths1 = Directory.GetDirectories(dirPaths[di]);
             for (int dii = 0; dii < dirPaths1.Length; dii++){
                 filePaths1 = Directory.GetFiles(dirPaths1[dii]);
                 for (int fii = 0; fii < filePaths1.Length; fii++) {
                     texturec.Add (new TextureC (filePaths1[fii]));
                 }
                 
                 dirPaths2 = Directory.GetDirectories(dirPaths1[dii]);
                 for (int diii = 0; diii < dirPaths2.Length; diii++){
                     filePaths2 = Directory.GetFiles(dirPaths2[diii]);
                     for (int fiii = 0; fiii < filePaths2.Length; fiii++) {
                         texturec.Add (new TextureC (filePaths2[fiii]));
                     }
                     
                     dirPaths3 = Directory.GetDirectories(dirPaths2[diii]);
                     for (int diiii = 0; diiii < dirPaths3.Length; diiii++){
                         filePaths3 = Directory.GetFiles(dirPaths3[diiii]);
                         for (int fiiii = 0; fiiii < filePaths3.Length; fiiii++) {
                             texturec.Add (new TextureC (filePaths3[fiiii]));
                         }
                         
                         dirPaths4 = Directory.GetDirectories(dirPaths3[diiii]);
                         for (int diiiii = 0; diiiii < dirPaths4.Length; diiiii++){
                             filePaths4 = Directory.GetFiles(dirPaths4[diiiii]);
                             for (int fiiiii = 0; fiiiii < filePaths4.Length; fiiiii++) {
                                 texturec.Add (new TextureC (filePaths4[fiiiii]));
                             }
                             
                             dirPaths5 = Directory.GetDirectories(dirPaths4[diiiii]);
                             for (int diiiiii = 0; diiiiii < dirPaths5.Length; diiiiii++){
                                 filePaths5 = Directory.GetFiles(dirPaths5[diiiiii]);
                                 for (int fiiiiii = 0; fiiiiii < filePaths5.Length; fiiiiii++) {
                                     texturec.Add (new TextureC (filePaths5[fiiiiii]));
                                 }
                             }
                         }
                     }
                 }
             }
         }
     }

and if you wander about class (nothing special yet)

my Class

 using UnityEngine;
 using System.Collections;
 
 [System.Serializable]
 
 public class TextureC {
     public string names ;
     public string paths ;
     public string filenames ;
     public Texture2D texture ;
     
     
     // Constructors
     public TextureC (){}
     public TextureC (string path){
         paths = path ;
     }
     public TextureC (Texture2D tex){
         texture = tex ;
     }
 }

sorry about generic list forgot how to make >< visible around TextureC (public list TextureC texturec)

How about Directory.GetFiles?

You can pass SearchOption.AllDirectories to Directory.GetFiles and it will recurse all subfolders for you.

:D totally forgot this one. However in some situations you might want to exculde certain directories.

Anyway +1

my mistake for comments thanks

 dirPaths = Directory.GetFiles(Application.dataPath + "/Resources/Textures/", "*.jpg" ,SearchOption.AllDirectories);

worked like charm

The easiest way is to use a recursive function. However you can also use a iterative loop, but in this case you have to use your own Stack / List / Queue.

 //C# - recursive (untested)
 public List<TextureC> texturec ;
 
 void ProcessDirectory(string aDir)
 {
     var files = Directory.GetFiles(aDir);
     foreach(var fileName in files)
     {
         texturec.Add(new TextureC(fileName));
     }
     var subDirs = Directory.GetDirectories(aDir);
     foreach(var subDir in subDirs)
     {
         ProcessDirectory(subDir);
     }
 }
 
 void ResizeTextures()
 {
     texturec = new List<TextureC>();
     ProcessDirectory(Application.dataPath + "/Resources/Textures/");
 }

I'm not sure if GetFiles and GetDirectories will return the full path or not, but the basice function should be the same.

i did it like this

when searching for unity files

GamesFound = Directory.GetFiles(LocationComp, "*.unity",SearchOption.AllDirectories);
