如何可以将某个文件夹（目录）下的所有子文件夹名(子文件夹下的也要）加入到ArrayList中？

Answer 1

private void GetFileInfo(string filePath, TreeNode node)
        {
            DirectoryInfo directoryInfo = new DirectoryInfo(filePath);
            try
            {
                foreach (DirectoryInfo childDirectoryInfo in directoryInfo.GetDirectories())
                {
                    TreeNode directoryNode = new TreeNode(childDirectoryInfo.Name.ToString());
                    directoryNode.Tag = childDirectoryInfo.Name.ToString();
                    GetFileInfo(filePath + "\\" + childDirectoryInfo.Name.ToString(), directoryNode);
                    node.Nodes.Add(directoryNode);
                }
                foreach (FileInfo fileInfo in directoryInfo.GetFiles("*.html"))
                {
                    TreeNode leafNode = new TreeNode();
                    leafNode.Text = fileInfo.Name.ToString().Substring(0,fileInfo.Name.ToString().IndexOf(".html"));
                    leafNode.Tag = fileInfo.Name.ToString();
                    node.Nodes.Add(leafNode);
                }
 }
            catch
            { 
            }
        }使用介绍:            TreeNode treenode = new TreeNode();
            treenode.Text = "报表树";
            GetFileInfo(@"C:\AutoReport", treenode);
            this.treeView1.Nodes.Add(treenode); 给个相关的给你

写的不好 见笑了
public class Test
{
      public static void Main()
  { 
       string   filename=@"D:\test";
       FileInfo file=new FileInfo(filename);
       List<string> list = new List<string>();
       AddDirectory(list, file);
   
     foreach(string s in list)
        {
            Console.WriteLine(s);
        }
   
}    static void  AddDirectory(List<string> list,FileInfo file) 
{
           
                 if (Directory.Exists(file.FullName)) 
{ 
string[] files = Directory.GetFileSystemEntries(file.FullName); 

if (files != null) 
{ 
for (int i = 0; i < files.Length; i++) 
{ 
AddDirectory( list,new FileInfo(files[i]));  
} 
} 
} 
else  
{ 
                //Console.WriteLine(file.Name);
list.Add(file.Name);
} 
              
} 
}

Answer 3

string [] Files; Files = Directory. GetFiles (@"",); 
foreach (string name in strFiles) 
{          
  arrFiles.Add(name);  
} 
大概就这样......

Answer 4

用迭代法
using System;
using System.Collections.Generic;
using System.Text;using System.IO;
using System.Collections;namespace CTTest
{
    class Program
    {
        private static ArrayList dirarray = new ArrayList();
        static void Main(string[] args)
        {
            string dir = @"D:\a";
            searchsubdir(dir);
            foreach (object sdir in dirarray)
            {
                Console.WriteLine(sdir.ToString());
            }
            Console.ReadKey();
        }        static void searchsubdir(string fatherdir)
        {
            string[] subdir = Directory.GetDirectories(fatherdir);
            for (int i = 0; i < subdir.Length; i++)
            {
                dirarray.Add(subdir[i]);
                searchsubdir(subdir[i]);
            }
        }
    }
}
