Remarks
The EntityReference class exposes the EntityKey of the related object and is a base class for the EntityReference<TEntity> class. An EntityReference<TEntity> object is returned by a navigation property when the related end has a multiplicity of zero or one. For more information, see NavigationProperty Element (CSDL).
Constructors
| EntityReference() |
Initializes a new instance of the EntityReference class. |
Properties
| EntityKey |
Returns the key for the related object. |
| IsLoaded |
Gets a value that indicates whether all related objects have been loaded. (Inherited from RelatedEnd) |
| RelationshipName |
Gets the name of the relationship in which this related end participates. (Inherited from RelatedEnd) |
| RelationshipSet |
Gets a reference to the metadata for the related end. (Inherited from RelatedEnd) |
| SourceRoleName |
Gets the role name at the source end of the relationship. (Inherited from RelatedEnd) |
| TargetRoleName |
Gets the role name at the target end of the relationship. (Inherited from RelatedEnd) |
Methods
| Attach<TEntity>(IEnumerable<TEntity>, Boolean) |
Defines a relationship between two attached objects. (Inherited from RelatedEnd) |
| Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
| GetEnumerator() |
Returns an IEnumerator that iterates through the collection of related objects. (Inherited from RelatedEnd) |
| GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| Load() |
When overridden in a derived class, loads the related object or objects into the related end with the default merge option. (Inherited from RelatedEnd) |
| Load(MergeOption) |
When overridden in a derived class, loads an object or objects from the related end with the specified merge option. (Inherited from RelatedEnd) |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
| Merge<TEntity>(IEnumerable<TEntity>, MergeOption, Boolean) |
Merges related entities into the local EntityCollection<TEntity>. (Inherited from RelatedEnd) |
| OnDeserialized(StreamingContext) |
Used internally to deserialize entity objects along with the RelationshipManager instances. (Inherited from RelatedEnd) |
| ToString() |
Returns a string that represents the current object. (Inherited from Object) |
| ValidateEntityForAttach<TEntity>(TEntity, Int32, Boolean) |
Determines whether an object can be attached to the local collection or reference. (Inherited from RelatedEnd) |
| ValidateLoad<TEntity>(MergeOption, String) |
Ensures that the related object or objects can be successfully loaded into the local collection or reference. (Inherited from RelatedEnd) |
| ValidateOwnerForAttach() |
Ensures that the object to which the related end belongs supports an attach operation. (Inherited from RelatedEnd) |
Events
| AssociationChanged |
Occurs when a change is made to a related end. (Inherited from RelatedEnd) |
