CSharp Methods

🎯 한 줄 통찰 (One-line insight)

C# calls these "methods" and only parenthetically notes "also known as functions" — a terminology choice with real teeth, since the Syntax chapter's rule that ALL code must live inside a class means C# genuinely has no free-standing functions the way C++ does; every "function" is necessarily a method of SOME class (even Main() itself lives inside class Program), and the naming-convention split flagged back in the Identifiers chapter (variables lowercase-first) is completed here: methods are explicitly recommended to start UPPERCASE (MyMethod), giving C# a hard camelCase-vs-PascalCase split by identifier KIND that neither C nor C++ enforces as a style convention. [S1]

🧠 핵심 개념 (Core concepts)

• Method — a block of code that only runs when called; used to perform actions and enable code reuse (define once, use many times). [S1]
• static void MethodName() { ... } — the minimal method skeleton, defined inside a class. [S1]
• static — means the method belongs to the CLASS itself, not to an object/instance of the class (object-based method access deferred to a later chapter). [S1]
• void — means the method has no return value (deferred detail to the Return Values chapter). [S1]
• PascalCase convention — method names should start with an UPPERCASE letter for readability, in contrast to the lowercase-starting convention recommended for variable names. [S1]
• Calling a method — MethodName(); — same method can be called any number of times, each call re-executing the body independently. [S1]

📖 세부 내용 (Details)

• Method definition: class Program { static void MyMethod() { // code to be executed } }. [S1]
• Single call: static void Main(string[] args) { MyMethod(); } → outputs "I just got executed!". [S1]
• Repeated calls: calling MyMethod(); three times in Main() prints the same message three times. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

• C++와 달리 클래스 밖의 자유 함수가 존재하지 않음: Syntax 챕터에서 확인된 "모든 코드는 class 안에" 원칙 때문에, C#은 C++처럼 클래스 밖에 독립적으로 존재하는 자유 함수를 가질 수 없고 모든 함수가 반드시 어떤 class의 메서드라는 점이 확인됨 — Main() 자체도 Program 클래스 안에 있음. [S1]
• 변수는 소문자, 메서드는 대문자로 시작하는 명명 규칙 분리가 완성됨: Identifiers 챕터에서 예고했던 변수 lowercase 시작 관례에 이어, 이번 챕터는 메서드명을 uppercase로 시작하도록 명시적으로 권장한다는 점이 확인됨 — 식별자 종류(변수 vs 메서드)에 따라 대소문자 관례가 갈라지는 C#만의 스타일 규칙. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — "I just got executed!"를 출력하는 메서드를 정의하고 여러 번 호출하는 예제가 원문에서 제시됨. [S1]

💻 코드 패턴 (Code patterns)

Minimal method definition and repeated calls (C#):

static void MyMethod()
{
    Console.WriteLine("I just got executed!");
}

static void Main(string[] args)
{
    MyMethod();
    MyMethod();
    MyMethod();
}
