Uwagi

Uwaga

Począwszy od .NET Framework 2.0, zalecamy utworzenie XmlWriter wystąpień przy użyciu metody i XmlWriterSettings klasy, aby korzystać z XmlWriter.Create nowych funkcji.

Jeśli wywołasz metodę WriteStartAttribute, możesz zamknąć atrybut za pomocą tej metody.

Atrybut można również zamknąć, wywołując ponownie wywołanie WriteStartAttribute metody , lub wywołując WriteAttributeStringmetodę WriteEndElement.
