Public

A class in C# is a blueprint for creating objects, defined with the class keyword.

This page covers Class in C#. For a language-agnostic introduction, see Class.

Defining a Class#

public class Player
{
}

public is the access modifier — it means the class can be used from anywhere in the program. The class body sits between the curly braces.

By convention, class names use PascalCase: Player, OddsAndEvens, RockPaperScissors.

Adding Fields and Properties#

A field stores data on the object. A property provides controlled access to that data.

A method in C# is a function defined inside a class that defines what an object can do.

This page covers Method in C#. For a language-agnostic introduction, see Method.

Defining a Method#

A C# method has an access modifier, a return type, a name, and a body.

public void Greet()
{
    Console.WriteLine("Hello!");
}

• public — the access modifier; public means the method can be called from anywhere
• void — the return type; void means the method returns nothing
• Greet — the method name; use PascalCase by convention
• () — the parameter list; empty here, but arguments go inside these parentheses

Return Types#

If a method produces a value, declare the return type instead of void and use return to send it back.
