Oqim va fayl tizimi bilan ishlash

Papkalar va fayllarni filtrlash
Papkalar va fayllarni qidirish usullari filtrlashni amalga oshirishga imkon beradi. Filtr sifatida ushbu usullarga shablon uzatiladi, ular ikkita to'ldiruvchini o'z ichiga olishi mumkin: * yoki yulduzcha belgisi (istalgan belgilar soniga mos keladi) va ? yoki savol belgisi (bitta belgiga mos keladi)
Masalan, “books” bilan boshlangan barcha papkalarni topamiz:

// Directory sinfi

string[] dirs = Directory.GetDirectories(dirName, "books*.");
// DirectoryInfo sinfi
var directory = new DirectoryInfo(dirName);
DirectoryInfo[] dirs = directory.GetDirectories("books*.");
Yoki ".exe" kengaytmali barcha fayllarni olish:
// Directory sinfi
string[] files = Directory.GetFiles(dirName, "*.exe");

// DirectoryInfo sinfi

var directory = new DirectoryInfo(dirName);
FileInfo[] files = directory.GetFiles("*.exe");
Katalogni yaratish
DirectoryInfo sinfi
string path = @"C:\SomeDir";
string subpath = @"program\avalon";
DirectoryInfo dirInfo = new DirectoryInfo(path);
if (!dirInfo.Exists)
{
dirInfo.Create();
}
dirInfo.CreateSubdirectory(subpath);

Dastlab, bunday katalog mavjudligini tekshiriladi, chunki agar u mavjud bo'lsa, u holda uni yaratib bo'lmaydi va dastur xatoga yo'l qo'yadi. Natijada, quyidagi yo'l olinadi: "C: \ SomeDir \ program \ avalon"

Directory sinfi yordamida xuddi shunga o‘xshash amalni bajarish
string path = @"C:\SomeDir";
string subpath = @"program\avalon";
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
Directory.CreateDirectory($"{path}/{subpath}");

Katalog haqida ma'lumotlari olish
string dirName = "C:\\Program Files";
DirectoryInfo dirInfo = new DirectoryInfo(dirName);
Console.WriteLine("Katalog nomi: "+dirInfo.Name);
Console.WriteLine("Katologning to`liq nomi: "+dirInfo.FullName);
Console.WriteLine("Katologni vaqtincha yaratish: "+dirInfo.CreationTime);
Console.WriteLine("Ildiz katalog: "+dirInfo.Root);
