Esempio

Nell'esempio seguente i valori dell'enumerazione vengono salvate in una matrice e i valori correnti delle proprietà ConsoleColor BackgroundColor e vengono ForegroundColor archiviati in variabili. Il colore di primo piano viene quindi modificato in ogni colore dell'enumerazione, ad eccezione del colore corrispondente allo sfondo corrente, e il colore di sfondo viene modificato in ogni colore dell'enumerazione, ad eccezione del colore corrispondente al primo piano ConsoleColor ConsoleColor corrente. Se il colore di primo piano corrisponde al colore di sfondo, il testo non è visibile. Infine, chiama il metodo ResetColor per ripristinare i colori originali della console.
