Beispiel

Im folgenden Beispiel wird versucht, einen nicht vorhandenen Typ aus der mscorlib-Assembly zu laden. Die resultierende Ausnahme wird abgefangen, und der TypeName-Wert und der Message-Wert werden angezeigt. Damit dieses Codebeispiel ausgeführt werden kann, müssen Sie den voll gekennzeichneten Assemblynamen bereitstellen. Informationen über das Abrufen des voll gekennzeichneten Assemblynamens finden Sie unter Assemblynamen.
