이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영. - Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들 (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거. - Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/ Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/ Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이 존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존). - Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/ JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동. - 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리. - Topic_Programming 최종 문서 수: 2784 → 3985.

CSharp Switch
🎯 한 줄 통찰 (One-line insight)
The switch(expression) { case x: ... break; default: ... break; } skeleton is structurally identical to C/C++'s switch statement — same case/break/default keywords, same "evaluate once, compare against each case" model — making Switch the fourth chapter in the C# series (after Comments, Operators, Special Characters) where the answer to "what's different from C++" is essentially nothing at the syntax level shown here. [S1]
🧠 핵심 개념 (Core concepts)
switch(expression)— evaluated exactly ONCE, then compared against eachcasevalue in order. [S1]case x:— if the switch expression matchesx, that block's code runs. [S1]break— exits the switch block immediately once a match's code has run, preventing execution from continuing into subsequent cases; described as saving execution time by skipping the rest of the block. [S1]default:— optional; runs when NO case matches the expression. [S1]
📖 세부 내용 (Details)
- Weekday-name example:
switch (day) { case 1: Console.WriteLine("Monday"); break; ... case 7: Console.WriteLine("Sunday"); break; }withday = 4→ outputs"Thursday". [S1] - Default fallback example:
switch (day) { case 6: ...Saturday...; break; case 7: ...Sunday...; break; default: Console.WriteLine("Looking forward to the Weekend."); break; }withday = 4(no matching case) → outputs"Looking forward to the Weekend."viadefault. [S1]
⚖️ 모순 및 업데이트 (Contradictions & updates)
- switch 구조가 C/C++와 동일:
switch/case/break/default키워드와 전체 구조가 C/C++의 switch문과 차이가 없다는 점이 확인됨 — Comments, Operators, Special Characters에 이은 네 번째 "구조 동일" 챕터. [S1]
🛠️ 적용 사례 (Applied in summary)
요일 번호(day)를 받아 요일 이름을 출력하는 switch문과, 매치되는 case가 없을 때 default로 넘어가는 예제가 원문에서 직접 실전 활용 사례로 제시됨. [S1]
💻 코드 패턴 (Code patterns)
Switch with break and default (C#):
int day = 4;
switch (day)
{
case 1:
Console.WriteLine("Monday");
break;
case 4:
Console.WriteLine("Thursday");
break;
default:
Console.WriteLine("Looking forward to the Weekend.");
break;
}
// Outputs "Thursday"
