Public Shared Function TryValidateObject (instance As Object, validationContext As ValidationContext, validationResults As ICollection(Of ValidationResult), validateAllProperties As Boolean) As Boolean

Parameters

instance: Object

Het object dat moet worden gevalideerd.

validationContext: ValidationContext

De context die het object beschrijft dat moet worden gevalideerd.

validationResults: ICollection<ValidationResult>

Een verzameling voor elke mislukte validatie.

validateAllProperties: Boolean

true om alle eigenschappen te valideren; als falsealleen vereiste kenmerken worden gevalideerd.

Retouren

Boolean

true als het object valideert; anders, false.

Kenmerken: RequiresUnreferencedCodeAttribute

Uitzonderingen

ArgumentNullException

instance is null.

ArgumentException

instance komt niet overeen met deObjectInstanceon validationContext.

Opmerkingen

Met deze methode wordt elke ValidationAttribute instantie geëvalueerd die is gekoppeld aan het objecttype. Ook wordt gecontroleerd of elke eigenschap die is gemarkeerd RequiredAttribute , is opgegeven. Hiermee worden de eigenschapswaarden van het object gevalideerd, indien validateAllProperties dat wel het geval is true , maar worden eigenschappen van de objecten die door de eigenschappen worden geretourneerd, niet recursief gevalideerd.
