C#中文件夹类Directory的常用操作，unity获取streamingAssets下所有的文件夹及文件生成树结构物体

Directory.CreateDirectory(@"D:\test");

Directory.Delete(@"D:\test",true);

if (Directory.Exists(@"D:\test")) {
				Directory.CreateDirectory(@"D:\test);
		}

string[] files = Directory.GetFiles(path);

  string[] directories = Directory.GetDirectories(path);

public class CubeGenerator : MonoBehaviour
{
    public GameObject folderPrefab; // 文件夹的Prefab
    public GameObject filePrefab; // 文件的Prefab

    void Start()
    {
        string streamingAssetsPath = Application.streamingAssetsPath;
        GenerateObjectTree(streamingAssetsPath, null);

       
    }

    void GenerateObjectTree(string path, Transform parent)
    {
        // 创建文件夹物体
        GameObject folderObject = Instantiate(folderPrefab, Vector3.zero, Quaternion.identity, parent);
        folderObject.name = Path.GetFileName(path);

        // 获取文件夹下的所有文件和文件夹
        string[] files = Directory.GetFiles(path);
        string[] directories = Directory.GetDirectories(path);

        // 递归处理文件夹
        foreach (string directory in directories)
        {
            GenerateObjectTree(directory, folderObject.transform);
        }

        // 创建文件物体
        foreach (string file in files)
        {
            if (file.EndsWith(".meta"))
            {
                continue;
            }
            GameObject fileObject = Instantiate(filePrefab, Vector3.zero, Quaternion.identity, folderObject.transform);
          
            fileObject.name = Path.GetFileName(file);
        }
    }
