Unity 获取指定路径文件夹下所有文件集合（递归写法）（二）

方法代码的使用：

    private List<string> fileList = new List<string>();

    /// <summary>
    /// 获取路径下所有文件以及子文件夹中文件
    /// </summary>
    /// <param name="path">全路径根目录</param>
    /// <param name="FileList">存放所有文件的全路径</param>
    /// <returns></returns>
    public static List<string> GetFile(string path, List<string> FileList)
    {
        DirectoryInfo dir = new DirectoryInfo(path);
        FileInfo[] fil = dir.GetFiles();
        DirectoryInfo[] dii = dir.GetDirectories();
        foreach (FileInfo f in fil)
        {
            //int size = Convert.ToInt32(f.Length);
            long size = f.Length;
            FileList.Add(f.FullName);//添加文件路径到列表中
        }
        //获取子文件夹内的文件列表，递归遍历
        foreach (DirectoryInfo d in dii)
        {
            GetFile(d.FullName, FileList);
        }
        return FileList;
    }

    private void GetShowFile(string rootPath)
    {
        if (string.IsNullOrEmpty(rootPath))
            return;

        var files = GetFile(rootPath, fileList);

        foreach (var item in files)
        {

            string info = new DirectoryInfo(item).Name;

            if (Path.GetExtension(info) == ".fbx")
            {
                string equipmentName = item;
                var tup = pool.Getprefab();
                tup.Item2.cusName.text = Path.GetFileNameWithoutExtension(equipmentName);
                tup.Item2.pathname = equipmentName;
                tup.Item2.ui.OnBeginDragEvent.AddListener((Transform tr) =>
                {
                    Debug.Log("Begin");
                    isres = false;
                    choose = equipmentName;
                });
                tup.Item2.ui.OnEndDragEvent.AddListener((Transform tr) =>
                {
                    Debug.Log("End");
                    Vector3 pos = Input.mousePosition;
                    if (GameApp.camera.ScreenPointToWorld(ref pos, 500))
                    {
                        LoadObj(pos);
                        Debug.Log("pos");
                    }
                    else
                    {
                        MessageBox.Ins.ShowOk("提示", "无法放置在该位置", "好的");
                    }
                });
                items.Add(tup.Item2);
            }

        }

    }
