Class definition

Context: A class definition specifies the members (fields, properties, methods, events) that instances of the class will have.

Syntax

[access modifier] class ClassName
{
    // members: fields, properties, methods, constructors, etc.
}

Example

public class Person
{
    // Fields
    private string _name;

    // Constructor
    public Person(string name)
    {
        _name = name;
    }

    // Method
    public void SayHello()
    {
        Console.WriteLine($"Hello, I'm {_name}");
    }
}

Naming Conventions

• Class names use PascalCase (e.g., CustomerService).
• File name usually matches the class name (e.g., Person.cs).
• One class per file is common but not mandatory.
