public:
System::Object ^ GetOriginalEntityState(System::Object ^ entity);public object GetOriginalEntityState (object entity);abstract member GetOriginalEntityState : obj -> objPublic Function GetOriginalEntityState (entity As Object) As ObjectParameters
- entity
- Object
The entity whose original value is to be retrieved.
Returns
A copy of the original entity. The value is null if the entity passed in is not tracked. Disconnected entities sent back by a client must be attached before the DataContext can begin to track their state. The "original state" of a newly attached entity is established based on values supplied by the client. The data context does not track the state of disconnected entities.
Remarks
Note the following:
The entity argument must be non-null. Otherwise, a null argument exception is thrown.
In the case of the strongly typed (
TEntity) method, the type must be mapped and must be an entity type. That is, it must have object ID information in its mapping. Otherwise, a wrong type exception is thrown.
