Interface IGetsEnumerableItemsToBeValidated

An object which can get a System.Collections.Generic.IEnumerable<T> of individual items to be validated, based upon an object which should implement the correct enumerable interface and an intended type.

Namespace: CSF.Validation.RuleExecution

Assembly: CSF.Validation.dll

Syntax

public interface IGetsEnumerableItemsToBeValidated

Methods

GetEnumerableItems(Object, Type)

Gets an enumerable collection of item values to be validatated.

Declaration

IEnumerable<object> GetEnumerableItems(object enumerableValue, Type itemType)

Parameters

Type	Name	Description
System.Object	enumerableValue	A value to be validated, which must implement System.Collections.Generic.IEnumerable<T> for a generic type specified by itemType.
System.Type	itemType	The expected generic type of the enumerable collection.

Returns

Type	Description
System.Collections.Generic.IEnumerable<System.Object>	Either a collection of item values from the enumerable, or a null reference if enumerableValue is null.

Remarks

Note that executing this method will enumerate the source collection and crystalise it into a finite collection. The order of items is defined by the order in which the source System.Collections.Generic.IEnumerable<T> provided them. There is no certainty that executing this method more than once would provide the items in the same order (or even the same items each time).

Exceptions

Type	Condition
ValidationException	If the enumerableValue does not implement System.Collections.Generic.IEnumerable<T> for the type itemType.
System.ArgumentNullException	If itemType is null.
