using namespace System;
int main()
{
   
   // Assume the current culture is en-US.
   // Create a DateTime for the first of May, 2003.

설명

열거형에 있는 DayOfWeek 상수의 값 범위는 DayOfWeek.Sunday 다음과 같습니다 DayOfWeek.Saturday. 정수로 캐스팅하는 경우 해당 값의 범위는 0부터 6(나타 DayOfWeek.Sunday낸 DayOfWeek.Saturday것)입니다.

이 속성은 DayOfWeek 열거형 상수이며 시스템의 지역 및 언어 설정을 반영하지 않습니다. 특정 날짜의 지역화된 평일 이름을 나타내는 문자열을 검색하려면 매개 변수를 포함하는 메서드의 ToString 오버로드 중 하나를 호출하고 해당 문자열 또는 dddd 사용자 지정 형식 문자열을 ddd 전달 format 합니다. 자세한 내용은 방법: 특정 날짜에서 요일 추출을 참조하세요.
