Examples

Negli esempi di codice seguenti viene illustrato come derivare dalla classe ConfigurationConverterBase per creare un tipo di convertitore TimeSpan personalizzato.The following code examples show how to derive from the ConfigurationConverterBase class to create a custom TimeSpan converter type. Negli esempi viene inoltre illustrato come utilizzare questo tipo in una sezione personalizzata.Also, the examples show how to use this type in a custom section.

Di seguito è riportato un estratto della configurazione usato dall'esempio precedente.The following is a configuration excerpt as used by the previous example.

Remarks

Il ConfigurationConverterBase è la classe di base per i tipi di configurazione del convertitore.The ConfigurationConverterBase is the base class for the converter configuration types. Si tratta di tipi che convertono le stringhe, individuate nel file di configurazione, da e verso le proprietà fortemente tipizzate correlate.These are types that convert strings, found in the configuration file, to and from the related strongly typed properties.

Constructors

ConfigurationConverterBase()

Inizializza una nuova istanza della classe ConfigurationConverterBase.Initializes a new instance of the ConfigurationConverterBase class.
