How to access subDirectories of a Directory in C#


A directory or a folder can contains multiple directories or files. If you want to access all those directories which is under in a parent directory Then you should use DirecotryInfo class for accessing subDirectories of a parent Directory.In previous example we had seen that how to create a subDirectory under parent Directory.Now in this example we will seen that how to access all subDirectories under parent Directory.

Logic behind the program is

Step-1 : Create a instance of DirectoryInfo Class with parent directory path.
Step-2 : Now check , If parent directory is exist or not in specified path
Step-3: If Exist then get all subdirectories under parent directory and assign to an array using GetDirectories() method
Step-4 : Items add into List.

NoteGetDirectories() method does not access compressed directories

namespace WindowsFormsApplication2
    public partial class Form5 : Form
        public Form5()

        private void button1_Click(object sender, EventArgs e)
            string dirpath = textBox1.Text;
            DirectoryInfo dirinfo = new DirectoryInfo(dirpath);
            if (dirinfo .Exists)
                DirectoryInfo[] subdir = dirinfo.GetDirectories();
