지정된 시작 태그를 작성하고 지정된 네임스페이스 및 접두사에 연결합니다.

public:
 override void WriteStartElement(System::String ^ prefix, System::String ^ localName, System::String ^ ns);
public override void WriteStartElement(string? prefix, string localName, string? ns);
public override void WriteStartElement(string prefix, string localName, string ns);
override this.WriteStartElement : string * string * string -> unit
Public Overrides Sub WriteStartElement (prefix As String, localName As String, ns As String)

매개 변수

prefix
String

요소의 네임스페이스 접두사입니다.

localName
String

요소의 로컬 이름입니다.

ns
String

요소와 연결할 네임스페이스 URI입니다. 이 네임스페이스가 이미 범위에 있고 연결된 접두사를 가지고 있는 경우 기록기는 자동으로 해당 접두사도 씁니다.

예외

InvalidOperationException

작성기가 닫혀 있습니다.

메모

새로운 기능을 활용하기 위해 XmlWriter 인스턴스를 XmlWriter.Create 메서드를 사용하고 XmlWriterSettings 클래스를 활용하여 만드는 것을 권장합니다.

이 메서드를 호출한 후 특성을 작성하거나 , WriteComment또는 WriteString 자식 요소를 사용하여 WriteStartElement콘텐츠를 만들 수 있습니다. 끝 태그가 기록되는 시점에 요소를 WriteEndElement 닫을 수 있습니다.
