XPathNavigator.CanEdit XPathNavigator.CanEdit XPathNavigator.CanEdit XPathNavigator.CanEdit Property

定義

XPathNavigator で、基になる XML データを編集できるかどうかを示す値を取得します。Gets a value that indicates whether the XPathNavigator can edit the underlying XML data.

public:
 virtual property bool CanEdit { bool get(); };
public virtual bool CanEdit { get; }
member this.CanEdit : bool
Public Overridable ReadOnly Property CanEdit As Boolean

プロパティ値

trueが基になる XML データを編集falseできる場合は。それ以外の場合は。XPathNavigatortrue if the XPathNavigator can edit the underlying XML data; otherwise, false.

次の例ではCanEdit 、プロパティを使用CanEditXPathDocumentて、クラスXmlDocumentとクラスの値を表示します。The following example uses the CanEdit property to display the CanEdit values of the XPathDocument and XmlDocument classes.

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)

この例は、books.xml ファイルを入力として使用します。The example takes the books.xml file as an input.

注釈

プロパティCanEditは、.NET Framework 内のIXPathNavigableインターフェイスの3つの異なる実装に基づいて異なる値を持ちます。The CanEdit property has different values based on the three different implementations of the IXPathNavigable interface in the .NET Framework. CanEdit実装にXPathNavigatorよって作成されたオブジェクトの値を、次の表に示します。The CanEdit values for XPathNavigator objects created by each implementation are listed in the following table.
