}

Natijasi:

Delete() – agar u bo'sh bo'lsa, bu DirectoryInfo ni yo'q qiladi.

Foydalanish misoli:

using System;
using System.IO;
class Test 
{
    public static void Main() 
    {
         DirectoryInfo di1 = new DirectoryInfo(@"C:\MyDir");
        try 
        {
            di1.Create();
            di1.CreateSubdirectory("temp");
            Console.WriteLine("Men {0}ni o'chirishga harakat qilyapman.", di1.Name);
            di1.Delete();
            Console.WriteLine("Yo'q qilish operatsiyasi tasodifan muvafaqqiyatli yuz berdi.");
        } 
        catch (Exception) 
        {
            Console.WriteLine("Yo'q qilish operatsiyasi kutilganidek muvafaqqiyatsiz yuz berdi.");
        } 
        finally {}
        Console.ReadKey();
    }
}

Natijasi:

Delete(Boolean) – pastki kataloglar va fayllarni yo'q qilish kerakligini aniqlab, DirectoryInfo ning ushbu nusxasini yo'q qiladi.

Foydalanish misoli:

          DirectoryInfo di = new DirectoryInfo(@"C:\TempDir");

         if (di.Exists == false)
          di.Create();
          DirectoryInfo dis = di.CreateSubdirectory("SubDir");
          Console.WriteLine("Katalog va pastki katalog muvafaqqiyatli yaratildi.");
          //True shuni ko'rsatadiki, agar ushbu katalogda pastki kataloglar
          // yoki fayllar bo'lsa, ular ham o'chiriladi.
          di.Delete(true);
          Console.WriteLine("Katalog va pastki katalog muvafaqqiyatli o'chirildi.");
          Console.ReadKey();
Natijasi:

GetDirectories() – belgilangan katalogdagi pastki kataloglarning nomlarini (shu jumladan yo’llarini) qaytaradi.

Foydalanish misoli:

using System;
using System.IO;
public class GetDirectoriesTest 
{
    public static void Main() 
    {
        DirectoryInfo di = new DirectoryInfo("C:\\");

        Console.Write("    'C:\\' diskdagi kataloglar:");
        Console.WriteLine();
        foreach (DirectoryInfo dri in diArr)
            Console.WriteLine("\t" +dri.Name);
        Console.ReadKey();
    }
}

Natijasi:

GetDirectories(String) – belgilangan katalogdagi qidiruv uslubiga mos keladigan pastki kataloglarning nomlarini (shu jumladan yo’llarini) qaytaradi.

GetDirectories(String, SearchOption) – belgilangan katalogdagi belgilangan qidiruv namunasiga mos keladigan pastki kataloglarning nomlarini (shu jumladan yo’llarini) va ixtiyoriy ravishda pastki kataloglarni qaytaradi.

Foydalanish misoli:

using System;
using System.IO;
public class GetDirectoriesTest 
{
    public static void Main() 
    {
        DirectoryInfo di = new DirectoryInfo("C:\\");
        DirectoryInfo[] diArr = di.GetDirectories("p*");   //("p*", SearchOption.TopDirectoryOnly)
        Console.Write("  'C:\\' diskdagi 'p' harfi bilan boshlanuvchi kataloglar:");
        Console.WriteLine();
        foreach (DirectoryInfo dri in diArr)
            Console.WriteLine("\t" +dri.Name);
        Console.ReadKey();
    }
}

Natijasi:

EnumerateDirectories() – joriy katalogdagi ma'lumotlarni sanaydigan to'plamni qaytaradi.

Foydalanish misoli:

using System;
using System.IO;
using System.Linq;
namespace EnumDir
{
    class Program
    {
        static void Main(string[] args)
        {
            string docPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
            DirectoryInfo dirPrograms = new DirectoryInfo(docPath);
            DateTime StartOf2019 = new DateTime(2019, 12, 04);
            var dirs = from dir in dirPrograms.EnumerateDirectories()
            where dir.CreationTimeUtc > StartOf2019
            select new
            {
                ProgDir = dir,
            };
            Console.WriteLine("(2019, 12, 04) sanadan boshlab yaratilgan kataloglar ro'yxati:"+"\n");
            foreach (var di in dirs)
            {
                Console.WriteLine(di.ProgDir.Name);
            }
              Console.ReadKey();
            }
     }
}

Natijasi:

EnumerateDirectories(String) – belgilangan yo’lda qidirish namunasiga mos keladigan katalogning to’liq nomlarini sanaydigan to’plamni qaytaradi.
