Nome	Descrizione
TryValidateObject(Object, ValidationContext, ICollection<ValidationResult>)	Determina se l'oggetto specificato è valido utilizzando il contesto di convalida e la raccolta dei risultati di convalida.
TryValidateObject(Object, ValidationContext, ICollection<ValidationResult>, Boolean)	Determina se l'oggetto specificato è valido utilizzando il contesto di convalida, la raccolta dei risultati di convalida e un valore che specifica se convalidare tutte le proprietà.

Commenti

Questo metodo valuta ogni ValidationAttribute istanza associata al tipo di oggetto. Controlla inoltre se viene fornita ogni proprietà contrassegnata con RequiredAttribute . Convalida i valori delle proprietà dell'oggetto se validateAllProperties è true ma non convalida in modo ricorsivo le proprietà degli oggetti restituiti dalle proprietà.
