Thread: file recursion help

How would I get all sub directories in the base master directory (C drive).

I also need to use this for the registry (please I know what I am doing)

well to bad the faq doesn't have any file recursion for C#.

I'm sure the c++ code is convertable but I really don't know c++ as good as C#.

can someone move this please, I feel like an idoit.

please move this to C# board.

thank you for your patients with me.

Moved to C# board as requested.

However you may want to provide a little bit more detail.

I want to collect the names of all of the directorys in the, lets say, C drive. From there I can get the names of the files, and any other info I need.

That is as clear as I can get it.

Simple recursion:

Code:

using System;
using System.Collections;
using System.IO;

namespace GetDirs
{
	class entry
	{
		static void Main(string[] args)
		{
			Test test = new Test();
			test.GetDirs(@"C:\");
			test.DumpDirs();
		}
	}

	class Test
	{
		private ArrayList directories = new ArrayList();

		public void GetDirs(string home)
		{
			string[] dirs1 = Directory.GetDirectories(home);
			foreach (string dir in dirs1)
			{
				directories.Add(dir);
				try
				{
					string[] dirs2 = Directory.GetDirectories(dir);
					if (dirs2.Length > 0)
						GetDirs(dir);
				}
				catch { }
			}
		}

		public void DumpDirs()
		{
			foreach (object obj in directories)
				Console.WriteLine((string)obj);
		}
	}
}

And here I modified the above example to do the same thing with registry keys:

Code:

using System;
using System.Collections;
using Microsoft.Win32;

namespace GetReg
{
	class entry
	{
		static void Main(string[] args)
		{
			Test test = new Test();
			test.GetRegKeys(Registry.ClassesRoot);
			test.GetRegKeys(Registry.CurrentUser);
			test.GetRegKeys(Registry.LocalMachine);
			test.GetRegKeys(Registry.Users);
			test.GetRegKeys(Registry.CurrentConfig);
			test.DumpRegKeys();
		}
	}

	class Test
	{
		private ArrayList regkeys = new ArrayList();

		public void GetRegKeys(RegistryKey homekey)
		{
			string[] subkeys = homekey.GetSubKeyNames();
			foreach (string subkey in subkeys)
			{
				try
				{
					regkeys.Add(homekey.Name + '\\' + subkey);
					RegistryKey subkey2 = homekey.OpenSubKey(subkey);
					if (subkey2.SubKeyCount > 0)
						GetRegKeys(subkey2);
					subkey2.Close();
				}
				catch { }
			}
		}

		public void DumpRegKeys()
		{
			foreach (object obj in regkeys)
				Console.WriteLine((string)obj);
		}
	}
}

I don't see where test is coming from? It isn't in Visual C# 2005 at least.


Edit: nvm I see now.

ok so how would I get the value of the key it is in as well. I have tried many, many things but I got no results.

Also, do a little search on recursion to understand why it works.

alright I should do some research by just by looking at it I can grasp how it works.

And thank you, I was alot confused on C# registry values. The registry can be confusing at times.
