Parámetros

instance: Object

Objeto que se va a validar.

validationContext: ValidationContext

Contexto que describe el objeto que se va a validar.

validationResults: ICollection<ValidationResult>

Colección que contiene cada validación con error.

Devoluciones

Boolean

true si el objeto se valida; de lo contrario, false.

Atributos: RequiresUnreferencedCodeAttribute

Excepciones

ArgumentNullException

instance es null.

ArgumentException

instanceno coincide con en ObjectInstancevalidationContext.

Comentarios

Este método evalúa cada ValidationAttribute instancia adjunta al tipo de objeto. También comprueba si se proporciona cada propiedad marcada con RequiredAttribute . No valida recursivamente los valores de propiedad del objeto.

Comentarios

Este método evalúa cada ValidationAttribute instancia adjunta al tipo de objeto. También comprueba si se proporciona cada propiedad marcada con RequiredAttribute . Valida los valores de propiedad del objeto si validateAllProperties es true pero no valida de forma recursiva las propiedades de los objetos devueltos por las propiedades.
