Si items es null, se crea un diccionario vacío. Si items no es null, el conjunto de pares clave-valor se copia en un nuevo diccionario, lo que impide que los consumidores modifiquen el diccionario original.

Parámetros

instance: Object

Objeto que se va a validar. Este parámetro es obligatorio.

serviceProvider: IServiceProvider

Objeto que implementa la IServiceProvider interfaz . Este parámetro es opcional.

items: IDictionary<Object,Object>

Diccionario de pares clave-valor para que estén disponibles para los consumidores del servicio. Este parámetro es opcional.

Atributos: RequiresUnreferencedCodeAttribute

Excepciones

ArgumentNullException

instance es null.

Comentarios

El serviceProvider parámetro representa un servicio que el método puede usar GetService para realizar la validación personalizada.

Si el items parámetro es null, se crea un diccionario vacío. Si el parámetro no nulles , el conjunto de pares clave-valor se copia en un nuevo diccionario, lo que impide que los consumidores del servicio modifiquen el diccionario original.

Parámetros

instance: Object

Instancia de objeto que se está validando. No se puede null.

displayName: String

Nombre para mostrar asociado a la instancia del objeto.

serviceProvider: IServiceProvider

Opcional IServiceProvider para usar cuando GetService(Type) se llama a .

Si es null, GetService(Type) siempre devolverá null.

items: IDictionary<Object,Object>

Conjunto opcional de pares clave-valor para que estén disponibles para los consumidores a través de Items.

Si nulles , se creará un diccionario vacío. Si no es null, el conjunto de pares clave-valor se copiará en un nuevo diccionario, lo que impide que los consumidores modifiquen el diccionario original.

Excepciones

ArgumentNullException

Cuándo instance es null

Comentarios

Este constructor es seguro para recortes porque no usa reflexión para resolver el tipo de instance para admitir la configuración de DisplayName.
