Die folgenden Codebeispiele zeigen, wie für die Ableitung der ConfigurationConverterBase erstellen Sie eine benutzerdefinierte Klasse TimeSpan Konvertertyp.The following code examples show how to derive from the ConfigurationConverterBase class to create a custom TimeSpan converter type. Darüber hinaus veranschaulicht die Beispiele zum Verwenden dieses Typs in einem benutzerdefinierten Abschnitt.Also, the examples show how to use this type in a custom section.

Die ConfigurationConverterBase ist die Basisklasse für den Konverter Konfigurationstypen.The ConfigurationConverterBase is the base class for the converter configuration types. Hierbei handelt es sich um Typen, die Zeichenfolgen zu konvertieren, finden Sie in der Konfigurationsdatei zu und von der stark typisierten Eigenschaften.These are types that convert strings, found in the configuration file, to and from the related strongly typed properties.
