XmlAttribute.Value-Eigenschaft

Ruft den Wert des Knotens ab oder legt diesen fest.

Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)

Syntax

'Declaration
Public Overrides Property Value As String
'Usage
Dim instance As XmlAttribute
Dim value As String

value = instance.Value

instance.Value = value

public override string Value { get; set; }

public:
virtual property String^ Value {
    String^ get () override;
    void set (String^ value) override;
}

/** @property */
public String get_Value ()

/** @property */
public void set_Value (String value)

public override function get Value () : String

public override function set Value (value : String)

Eigenschaftenwert

Der zurückgegebene Wert hängt vom NodeType des Knotens ab. Bei XmlAttribute-Knoten ist diese Eigenschaft der Wert des Attributs.

Ausnahmen

Ausnahmetyp	Bedingung
ArgumentException	Der Knoten ist schreibgeschützt, und ein Set-Vorgang wird aufgerufen.

Beispiel

Im folgenden Beispiel werden Informationen über die einzelnen Knoten in der Attributauflistung angezeigt.
