예제
다음 샘플 코드에서는 HttpRequestHeaderCollection 개체의 속성을 사용하여 HttpRequestMessage 개체에서 요청 헤더를 가져와서 설정하는 메서드를 보여 줍니다. 또한 Windows.Web.Http.Headers 네임스페이스에는 유효성 검사를 사용하여 헤더를 가져와서 설정하는 데 사용할 수 있는 특정 HTTP 헤더에 대한 강력한 형식의 헤더 컬렉션 및 값 클래스가 많이 있습니다.

설명
HttpRequestHeaderCollection은 HTTP 요청과 연결된 HTTP 헤더의 컬렉션입니다. HttpRequestHeaderCollection 개체를 사용하여 HTTP 요청에서 특정 헤더를 얻거나 설정할 수 있습니다. HttpRequestHeaderCollection 개체의 대부분의 속성은 특정 HTTP 헤더의 값에 대한 액세스를 제공합니다.
HttpRequestMessage의 Headers 속성은 HttpRequestHeaderCollection 개체를 반환합니다. HttpClient의 DefaultRequestHeaders 속성은 HttpRequestHeaderCollection 개체도 반환합니다. HttpRequestHeaderCollection 개체를 생성하는 두 가지 메서드입니다.
HttpRequestHeaderCollection은 앱 개발자가 설정할 수 있는 HTTP 요청의 HTTP 헤더를 나타내며, 결국 요청과 함께 전송될 수 있는 모든 헤더는 아닙니다. HttpBaseProtocolFilter는 일부 추가 헤더를 추가합니다.
HTTP 요청의 헤더는 기본 스택에서 변경할 수 있습니다. 따라서 요청이 완료된 후 앱이 HttpRequestHeaderCollection에서 헤더 값을 가져올 수 있습니다.
C# 또는 Microsoft Visual Basic에서 컬렉션 열거
C# 또는 Microsoft Visual Basic에서 HttpRequestHeaderCollection 개체를 반복할 수 있습니다.
foreach 구문 사용과 같은 대부분의 경우 컴파일러는 이 캐스팅을 수행하므로 명시적으로 캐스팅 IEnumerable
할 필요가 없습니다.
예를 들어 GetEnumerator를 호출하려는 경우 명시적으로 캐스팅해야 하는 경우 컬렉션 개체를 제약 조건으로 String 및 String의 KeyValuePair를 사용하여 IEnumerable<T>로 캐스팅합니다.
