ObjectStateManager::TryGetRelationshipManager Method (Object^, RelationshipManager^%)

Assembly: System.Data.Entity (in System.Data.Entity.dll)
public: bool TryGetRelationshipManager( Object^ entity, [OutAttribute] RelationshipManager^% relationshipManager )
Parameters
- entity
-
Type:
System::Object^
The object for which to return the RelationshipManager.
- relationshipManager

Type:
System.Data.Objects.DataClasses::RelationshipManager^%
When this method returns, contains the RelationshipManager for the entity.
Return Value
Type: System::Booleantrue if a RelationshipManager instance was returned for the supplied entity; otherwise false.
The GetRelationshipManager method is used to obtain the RelationshipManager for objects that are persistence ignorant. When objects implement IEntityWithRelationships or inherit from EntityObject, the RelationshipManager is accessed from the RelationshipManager property.
The RelationshipManager cannot be returned when the object is in a Detached state.
Calling the TryGetRelationshipManager method is the same as calling the GetRelationshipManager method, except that this method returns false instead of raising an exception.
