The IEntityFields type exposes the following members.

Properties

	Name	Description
	Count	Gets the number of slots allocated in this fields object. (Inherited from IEntityFieldsCore.)
	FieldsWithExpressionOrAggregate	Gets the fields with expression or aggregate. (Inherited from IEntityFieldsCore.)
	InheritanceInfoProviderToUse	Gets the inheritance info provider to use. (Inherited from IEntityFieldsCore.)
	IsChangedInThisEditCycle	Flag to signal if the entity fields have changed during an edit cycle which is controlled outside this IEntityFieldsCore object. If set to true, EndEdit will succeed, otherwise EndEdit will ignore any changes, since these are made in a previous edit cycle which is already ended. (Inherited from IEntityFieldsCore.)
	IsDirty	Gets / sets the flag if the contents of the EntityFields2 object is 'dirty', which means that one or more fields are changed. (Inherited from IEntityFieldsCore.)
	IsFixedSize	Gets a value indicating whether the IList has a fixed size. (Inherited from IList.)
	IsReadOnly	Gets a value indicating whether the ICollectionT is read-only. (Inherited from ICollectionIEntityFieldCore.)
	IsSynchronized	Gets a value indicating whether access to the ICollection is synchronized (thread safe). (Inherited from ICollection.)
	ItemInt32	Gets / sets the EntityField on the specified Index.
	ItemString	Gets the EntityField with the specified name.
	OwnPrimaryKeyFieldInfos	Gets the primary key field infos of the pk fields owned by this entity, so not the pk fields inherited from a supertype. If this entity isn't in a TPE inheritance hierarchy, this property is equal to PrimaryKeyFieldInfos (Inherited from IEntityFieldsCore.)
	PrimaryKeyFieldInfos	Gets the primary key field infos. Similar to PrimaryKeyFields, but this property doesn't trigger field creation. (Inherited from IEntityFieldsCore.)
	PrimaryKeyFields	List of IEntityField references which form the primary key
	State	The state of the IEntityFieldsCore object (Inherited from IEntityFieldsCore.)
	SyncRoot	Gets an object that can be used to synchronize access to the ICollection. (Inherited from ICollection.)

	Add(Object)	Adds an item to the IList. (Inherited from IList.)
	Add(T)	Adds an item to the ICollectionT. (Inherited from ICollectionIEntityFieldCore.)
	BeginEdit	Begins an edit on an object. (Inherited from IEditableObject.)

	CleanAndPreserveExpressionsFromFields	Removes the expressions from fields and returns them in the dictionary, key is field index, value is the expression on that field. Only removes expressions from fields which have a non-empty containingobjectname, as those are real entity fields. (Inherited from IEntityFieldsCore.)

	Clone	Clones this instance and its contents using a deep copy.
	CloneAsDirty	Clones this object to a new EntityFields object where all fields are changed and the object itself is marked dirty.
	Compact	Compacts the list of fields so all empty slots are removed. (Inherited from IEntityFieldsCore.)
	Contains(Object)	Determines whether the IList contains a specific value. (Inherited from IList.)
	Contains(T)	Determines whether the ICollectionT contains a specific value. (Inherited from ICollectionIEntityFieldCore.)
	Contract	Contracts the list of fields so all empty slots at the end of the list of fields are removed. Doesn't perform a contract operation if the fields object is empty (Inherited from IEntityFieldsCore.)
	CopyTo(Array, Int32)	Copies the elements of the ICollection to an Array, starting at a particular Array index. (Inherited from ICollection.)
	CopyTo(T, Int32)	Copies the elements of the ICollectionT to an Array, starting at a particular Array index. (Inherited from ICollectionIEntityFieldCore.)

	EndEdit	Pushes changes since the last BeginEdit or AddNew call into the underlying object. (Inherited from IEditableObject.)
	Expand	Expands this entity fields object by appending numberOfCells new cells to this object. (Inherited from IEntityFieldsCore.)
	ForcedValueWrite(Int32, Object)	Sets the current value for the field with the index specified to the currentValue specified without setting changed flags. From user code, use SetCurrentValue instead. (Inherited from IEntityFieldsCore.)
	ForcedValueWrite(Int32, Object, Object)	Sets the current value for the field with the index specified to the currentValue specified and the dbvalue to the dbvalue specified without setting changed flags. From user code, use SetCurrentValue instead. (Inherited from IEntityFieldsCore.)
	GetAsEntityFieldCoreArray	Returns the complete list of IEntityFieldCore objects as an array of IEntityFieldCore objects. (Inherited from IEntityFieldsCore.)
	GetAsPersistenceInfoArray	Returns the complete list of IEntityField objects as an array of IFieldPersistenceInfo objects. IEntityField objects implement IFieldPersistenceInfo.

	GetHashCode	Overrides the GetHashCode routine. It will calculate a hashcode for this set of entity fields using the eXclusive OR of the hashcodes of the primary key fields in this set of entity fields. That hashcode is returned. If no primary key fields are present, the hashcode of the base class is returned, which will not be unique. (Inherited from IEntityFieldsCore.)

Extension Methods

	Name	Description
	InT	Creates a predicate which is true if there's an object of type T in values, which has for each property P a field in fields with the same name / alias and the value for property P is equal to the value of the field equivalent in the main query. (Defined by InPredicateProducers.)
	NotInT	Creates a predicate which is true if there's no object of type T in values, which has for each property P a field in fields with the same name / alias and the value for property P is equal to the value of the field equivalent in the main query. (Defined by InPredicateProducers.)
