Oqim va fayl tizimi bilan ishlash

Directory yoki DirectoryInfo
Funktsionallikdan ko'rinib turibdiki, ikkala sinf ham o'xshash xususiyatlarni taqdim etadi. Qachon va nimadan foydalanish kerak? Agar bitta katalog bilan bir yoki ikkita amalni bajarish kerak bo'lsa, u holda Directory sinfidan foydalanish osonroq. Agar bir xil katalogda amallar ketma-ketligini bajarish kerak bo'lsa, unda DirectoryInfo sinfidan foydalangan ma'qul. Nega? Gap shundaki, Directory sinfining usullari qo'shimcha xavfsizlik tekshiruvlarini amalga oshiradi. Va DirectoryInfo sinfi uchun bunday tekshiruvlar har doim ham talab qilinmaydi.

Demak, ushbu sinflarni qo'llash misollarini ko'rib chiqamiz.

Fayllar va qism kataloglar ro'yxatini olish
string dirName = "C:\\";

if (Directory.Exists(dirName))

{
Console.WriteLine("Qism katolog:");
string[] dirs = Directory.GetDirectories(dirName);
foreach (string s in dirs)
{
Console.WriteLine(s);
}
Console.WriteLine();
Console.WriteLine("Fayllar:");
string[] files = Directory.GetFiles(dirName);
foreach (string s in files)
{
Console.WriteLine(s);
}
}
Fayl nomlaridagi slesh chiziqlardan foydalanishga e'tibor bering. Yoki ikkita slesh chiziqdan foydalaniladi: "C: \\" yoki bitta slesh, lekin keyin @ belgisini butun yo'lning oldida qo'yamiz : @ "C: \ Program Files".
DirectoryInfo bilan o'xshash misol:

string dirName = @"C:\";

var directory = new DirectoryInfo(dirName);

if (directory.Exists)

{
Console.WriteLine("Qism katologlar:");
DirectoryInfo[] dirs = directory.GetDirectories();
foreach (DirectoryInfo dir in dirs)
{
Console.WriteLine(dir.FullName);
}
Console.WriteLine();
Console.WriteLine("Fayllar:");
FileInfo[] files = directory.GetFiles();
foreach (FileInfo file in files)
{
Console.WriteLine(file.FullName);
}
}
