Looping a directory with subdirectories?

Question

I am working on a windows application in VS2005 C#. The problem is that I will read a directory for files. I have a foreach so I can loop al the files in the directory. Know I wil do the same but for the subdirectories also. So I think there must be a second foreach and place the subdir in the method. Someone who can help me??

Here is some test code:

public void test(String path)
{
DirectoryInfo root = new DirectoryInfo(path);

DirectoryInfo[] dirs = root.GetDirectories();

String bla = "";
foreach (DirectoryInfo subDir in dirs)
{
bla += subDir.Name.ToString()+"-----";
}
richTextBox1.Text = bla;
}

You could use the DirectoryInfo.GetFiles() to get all the files in a directory public void test( String path) { DirectoryInfo root = new DirectoryInfo (path); DirectoryInfo [] dirs = root.GetDirectories( *  SearchOption .AllDirectories); String bla =  ; foreach ( DirectoryInfo subDir in dirs) { bla += subDir.FullName.ToString() + Environment .NewLine; FileInfo[] files = directory.GetFiles(); foreach (FileInfo file in files) { Console.WriteLine(file.FullName); } } rtb1.Text = bla; } if you want to get the files in the root for processing as well use root.GetFiles() before the loop

Thanks for your support! I have only one problem and that is that I will do something with all the files in the dir and subdirs. Know it is so that I only can do somenthing with the directories. So can you please explain that?

Hello: Use the search option for GetDirectories: public void test( String path) { DirectoryInfo root = new DirectoryInfo (path); DirectoryInfo [] dirs = root.GetDirectories( *  SearchOption .AllDirectories); String bla =  ; foreach ( DirectoryInfo subDir in dirs) { bla += subDir.FullName.ToString() + Environment .NewLine; } rtb1.Text = bla; }
