Beschreibung

Weist dem Variant-Objekt das in rhs angegebene Variant-Objekt zu.

Die tatsächlichen Typen des Variant-Objekts bestimmen das Ergebnis der Operation. Die Zuweisung erfolgt nur dann, wenn die Variant-Objekte in Datentypen konvertiert werden können, die für die Operation geeignet sind. Wenn eine dieser Operationen wegen einer ungültigen Variant-Typumwandlung scheitert, wird eine EVariantError-Exception ausgelöst.
