using System;using System.Collections.Generic;using System.IO;private List<string> finded_files = new List<string>();private void RecursiveGetFiles(string parent_path){    string[] files = Directory.GetFiles(parent_path);    foreach (string file in files)    {        // 这里能够进行文件的过滤，比方筛选指定的后缀        finded_files.Add(file);    }    string[] paths = Directory.GetDirectories(parent_path);    foreach (string path in paths)    {        RecursiveGetFiles(path);    }}
