설명

이 메서드가 반환되면 stream 열려 있고 stream 내의 현재 위치는 정의되지 않습니다.

저장 작업의 일부로 현재 선택 영역의 콘텐츠를 dataFormat지정한 데이터 형식으로 변환할 수 있습니다.

설명

preserveTextElements false사용자 지정 TextElement 개체는 알려진 TextElement 형식으로 저장됩니다. 예를 들어 Paragraph상속하는 Heading1라는 사용자 지정 TextElement 만듭니다. preserveTextElements false설정하여 이 메서드를 호출하면 TextRange 저장되면 Heading1Paragraph 변환됩니다. preserveTextElements true설정하여 이 메서드를 호출하면 변환되지 않고 Heading1 저장됩니다. 사용자 지정 텍스트 요소를 유지하려면 dataFormatDataFormats.Xaml설정해야 합니다.

Save(Stream, String, Boolean) .NET Framework 버전 3.5에 도입되었습니다. 자세한 내용은 버전 및 종속성참조하세요.
