지정된 이름과 선택적 특성을 사용하여 DOCTYPE 선언을 작성합니다.

public:
 override void WriteDocType(System::String ^ name, System::String ^ pubid, System::String ^ sysid, System::String ^ subset);

public override void WriteDocType (string name, string? pubid, string? sysid, string? subset);

public override void WriteDocType (string name, string pubid, string sysid, string subset);

override this.WriteDocType : string * string * string * string -> unit

Public Overrides Sub WriteDocType (name As String, pubid As String, sysid As String, subset As String)

매개 변수

name

String

DOCTYPE의 이름입니다. 이 이름은 비어 있지 않아야 합니다.

pubid

String

null이 아닌 경우 PUBLIC "pubid" "sysid"도 씁니다. 여기서 pubid와 sysid는 지정된 인수 값으로 바뀝니다.

sysid

String

pubid가 null이고 sysid가 null이 아닌 경우 SYSTEM "sysid"를 씁니다. 여기서 sysid는 이 인수 값으로 바뀝니다.

subset

String

null이 아닌 경우 하위 집합이 이 인수 값으로 대체되는 [subset]을 작성합니다.

예외

InvalidOperationException

이 메서드가 루트 요소 다음의 프롤로그 외부에서 호출된 경우

ArgumentException

name이 null 또는 String.Empty인 경우

또는 name의 값이 잘못된 XML이 되는 경우

예제

다음 예제에서는 책을 나타내는 XML 파일을 씁니다.

설명

참고

.NET Framework 2.0부터 메서드와 XmlWriterSettings 클래스를 사용하여 XmlWriter.Create 새 기능을 활용하여 인스턴스를 만드는 XmlWriter 것이 좋습니다.

이 메서드는 잘못된 문자(또는 subset.)를 sysid pubid확인하지 않습니다. 또한 내부 하위 집합이 올바른 형식인지는 확인하지 않습니다.

중요

메서드에 XmlTextWriter 전달되는 WriteDocType 데이터의 유효성을 검사하지 않습니다. 이 메서드에 임의의 데이터를 전달하면 안 됩니다.
