XPathNavigator.CanEdit Свойство

public:
 virtual property bool CanEdit { bool get(); };

public virtual bool CanEdit { get; }

member this.CanEdit : bool

Public Overridable ReadOnly Property CanEdit As Boolean

true Значение , если может изменять базовые XML-данные; в XPathNavigator противном случае — значение false.

В следующем примере свойство используется для CanEdit отображения значений CanEditXPathDocument классов и XmlDocument .

XPathDocument^ readOnlyDocument = gcnew XPathDocument("books.xml");
XPathNavigator^ readOnlyNavigator = readOnlyDocument->CreateNavigator();

XmlDocument^ editableDocument = gcnew XmlDocument();
editableDocument->Load("books.xml");
XPathNavigator^ editableNavigator = editableDocument->CreateNavigator();

Console::WriteLine("XPathNavigator.CanEdit from XPathDocument: {0}", readOnlyNavigator->CanEdit);
Console::WriteLine("XPathNavigator.CanEdit from XmlDocument: {0}", editableNavigator->CanEdit);

XPathDocument readOnlyDocument = new XPathDocument("books.xml");
XPathNavigator readOnlyNavigator = readOnlyDocument.CreateNavigator();

XmlDocument editableDocument = new XmlDocument();
editableDocument.Load("books.xml");
XPathNavigator editableNavigator = editableDocument.CreateNavigator();

Console.WriteLine("XPathNavigator.CanEdit from XPathDocument: {0}", readOnlyNavigator.CanEdit);
Console.WriteLine("XPathNavigator.CanEdit from XmlDocument: {0}", editableNavigator.CanEdit);

Dim readOnlyDocument As XPathDocument = New XPathDocument("books.xml")
Dim readOnlyNavigator As XPathNavigator = readOnlyDocument.CreateNavigator()

Dim editableDocument As XmlDocument = New XmlDocument()
editableDocument.Load("books.xml")
Dim editableNavigator As XPathNavigator = editableDocument.CreateNavigator()

Console.WriteLine("XPathNavigator.CanEdit from XPathDocument: {0}", readOnlyNavigator.CanEdit)
Console.WriteLine("XPathNavigator.CanEdit from XmlDocument: {0}", editableNavigator.CanEdit)

В примере в качестве входных данных используется файл books.xml.
