Commenti

Questo NumberFormatInfo oggetto restituito da questa proprietà non cambia, indipendentemente dalle impostazioni cultura correnti. Rappresenta le convenzioni di formattazione delle impostazioni cultura invarianti, ovvero impostazioni cultura associate alla lingua inglese, ma non a qualsiasi paese/area geografica. Le impostazioni cultura invarianti vengono usate nelle operazioni di formattazione indipendenti dalle impostazioni cultura o che producono stringhe di risultati adatte per la visualizzazione in più impostazioni cultura.
