XmlSignificantWhitespace.NodeType Свойство

Определение

Возвращает тип текущего узла.Gets the type of the current node.

public:
 virtual property System::Xml::XmlNodeType NodeType { System::Xml::XmlNodeType get(); };
public override System.Xml.XmlNodeType NodeType { get; }
member this.NodeType : System.Xml.XmlNodeType
Public Overrides ReadOnly Property NodeType As XmlNodeType

Значение свойства

Для узлов XmlSignificantWhitespace это значение — XmlNodeType.SignificantWhitespace.For XmlSignificantWhitespace nodes, this value is XmlNodeType.SignificantWhitespace.

Примеры

В следующем примере в документ добавляется значащий пробел.The following example adds significant white space to the document.
