CultureInfo.IsReadOnly-Eigenschaft

Ruft einen Wert ab, der angibt, ob die aktuelle CultureInfo schreibgeschützt ist.

Namespace: System.Globalization
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public ReadOnly Property IsReadOnly As Boolean
'Usage
Dim instance As CultureInfo
Dim value As Boolean

value = instance.IsReadOnly

public bool IsReadOnly { get; }

public:
property bool IsReadOnly {
    bool get ();
}

/** @property */
public boolean get_IsReadOnly ()

public function get IsReadOnly () : boolean

Eigenschaftenwert

true, wenn die aktuelle CultureInfo schreibgeschützt ist, andernfalls false. Der Standardwert ist false.

Hinweise

Wenn die CultureInfo schreibgeschützt ist, sind die DateTimeFormat-Instanz und die NumberFormat-Instanz ebenfalls schreibgeschützt.

Beispiel

Folgender Beispielcode zeigt, dass auch IsReadOnly den Schutz der CultureInfo zugeordneten Instanzen DateTimeFormatInfo und NumberFormatInfo unterstützt.
