Unity editor extends C to traverse all pictures in folders and subdirectories

Below is the editor extension I wrote myself about traversing all the pictures under the folder and subdirectories , For reference only

    [MenuItem(" Editor Extension about atlas /C# Traverse all pictures in folders and subdirectories ")]
    static void RefreshAllPicture()
    {
    
        string[] DebugAllImage = new string[] {
     };

         DebugAllImage=KnowAllPicture();

    }


    public static string[]  KnowAllPicture()
    {
    
        List<string> liststring = new List<string>();

        string myfolderPath = "PicTureFolder";
        string path = Path.Combine(Application.dataPath, myfolderPath);

        var images = Directory.GetFiles(path, ".", SearchOption.AllDirectories).Where(s => s.EndsWith(".png") || s.EndsWith(".jpg"));

        foreach(var i in images)
        {
    
            var str = i.Replace(Application.dataPath, "");
            var strpath = str.Replace("\\", "/");
            strpath = "Assets" + strpath;
            liststring.Add(strpath);
        }

        foreach(var item in liststring)
        {
    
            Debug.Log($"ITem:{
      item}\n");
        }

        return liststring.ToArray();
    }
