少有人走的路

一段常用的代码，取指定目录下所有的文件，并且会递归搜索所有子目录下的文件。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApp1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            File.WriteAllText("d:\\fileList.txt", getfileNames("C:\\Users\\Administrator\\Desktop\\529\\all\\123"));
        }


        public string getfileNames(string rootPath)
        {
            StringBuilder sw = new StringBuilder();
            try
            {
                getDirectory(sw, rootPath, 2);
                return sw.ToString();
            }
            catch (IOException e)
            {
                return "";
            }

        }
        public static void getFileName(StringBuilder sw, string path, int indent,string externName)
        {
            DirectoryInfo root = new DirectoryInfo(path);
            foreach (FileInfo f in root.GetFiles())
            {
                if (f.FullName.EndsWith(externName))
                    sw.Append(f.FullName + "\r\n");
            }
        }

        public static void getDirectory(StringBuilder sw, string path, int indent)
        {
            getFileName(sw, path, indent,".bmp");
            DirectoryInfo root = new DirectoryInfo(path);
            foreach (DirectoryInfo d in root.GetDirectories())
            {
                getDirectory(sw, d.FullName, indent + 2);
            }
        }
    }
}
