Get only all folders recursive

I was reading that once you find a exception trying to access to a directory the function interrupt and don’t continue with the next directory (at least that’s what i need). ¿any idea how can i workaround the problem?

I just looking for some folders to show..

C# .Net

Thanks advance

        static void WalkDirectoryTree(System.IO.DirectoryInfo root)
    {
        try
        {
            System.IO.DirectoryInfo[] subDirs = null;

            // Now find all the subdirectories under this directory.
            subDirs = root.GetDirectories();

            foreach (System.IO.DirectoryInfo dirInfo in subDirs)
            {
                // Resursive call for each subdirectory.
                WalkDirectoryTree(dirInfo);
            }
        }
        catch (Exception)
        {

            //Do nothing
        } 
    }

>Solution :

You need to narrow the scope of your try catch to be inside the foreach loop

static void WalkDirectoryTree(System.IO.DirectoryInfo root)
{
    System.IO.DirectoryInfo[] subDirs = null;

    // Now find all the subdirectories under this directory.
    subDirs = root.GetDirectories();

    foreach (System.IO.DirectoryInfo dirInfo in subDirs)
    {
        // Resursive call for each subdirectory.
        try 
        {
            WalkDirectoryTree(dirInfo);
        }
        catch (Exception)
        {
        } 

    }
}

This will then catch the exception but continue with the next directory.
