설명

빈 DataSet 항목이 만들어지고 .와 연결됩니다 XmlDataDocument.

XmlDataDocument(DataSet)

지정된 XmlDataDocument를 사용하여 DataSet 클래스의 새 인스턴스를 초기화합니다.

public:
 XmlDataDocument(System::Data::DataSet ^ dataset);

public XmlDataDocument (System.Data.DataSet dataset);

new System.Xml.XmlDataDocument : System.Data.DataSet -> System.Xml.XmlDataDocument

Public Sub New (dataset As DataSet)

매개 변수

dataset

DataSet

DataSet에 로드할 XmlDataDocument입니다.

설명

지정된 XmlDataDocument .와 동기화됩니다 DataSet. 의 모든 데이터는 .를 DataSet 통해 XmlDataDocument즉시 사용할 수 있습니다. 의 DataSet 모든 변경 내용은 .에 XmlDataDocument전파됩니다. 스키마와 XmlDataDocument일치하는 DataSet 경우 변경된 내용은 .에 DataSet전파됩니다.
