Printer.WriteLine(person.name);

Printer.Read();

}

Taxalluslar

class User

{

public string name;

}

}

Sinf User deb nomlanadi, ammo dasturda uning o’rniga Person taxallusidan foydalanadi.

Shuningdek C# da sinflarning funksionalligini import qilish imkoniyati mavjud. Masalan, Console sinfining imkoniyatlarini import qilaylik:

Taxalluslar

using static System.Console;

namespace HelloApp

{

class Program

{

static void Main(string[] args)

{

WriteLine("Hello from C# 8.0");

Read();

}

}

}

Taxalluslar

using static System.Console;

namespace HelloApp

{

class Program

{

static void Main(string[] args)

{

WriteLine("Hello from C# 8.0");

Read();

}

}

}

 using static ifodasi dasturga barcha statik metodlarni, xususiyatlarni, shuningdek o’zgarmas (konstanta) larni qo’shadi. Va shundan so’nggina metodni chaqirishda sinf nomini ko’rsatmasdan qoldirib yuborish mumkin.

Taxalluslar

Xuddi shunday, foydalanuvchi tomonidan aniqlanadigan sinflarni belgilash va ularni import qilish mumkin:

using static System.Console;

using static System.Math;

using static HelloApp.Geometry;

namespace HelloApp

{

class Program

{

static void Main(string[] args)

{

double radius = 50;

double result = GetArea(radius); //Geometry.GetArea

WriteLine(result); //Console.WriteLine

Read(); // Console.Read

}

}

Taxalluslar

class Geometry

{

public static double GetArea(double radius)

{

return PI * radius * radius; // Math.PI
