Question

1. I am trying to mark the objects for deletion.

2. I have overridden the Savechnages method, and want to get all the entities regardless of their state. The code below is take from a site, the problem is the objects whose properties have not been changed, and simply marked for deletion don’t show up.

   public override int SaveChanges(SaveOptions options)
   {
       var deletedEntities = __getDeletedEntities();
       _softDelete(deletedEntities);
       return base.SaveChanges(options);
   }
   
   private List<ISoftDelete> __getDeletedEntities()
   {
   
      return ObjectStateManager
                .GetObjectStateEntries(EntityState.Unchanged)
                       .Select(entry => entry.Entity)
                       .OfType<ISoftDelete>()
                       .Where(e => e.IsDeleted)
                       .ToList();
   

   }

Q: Is there any other way rather than using GetObjectStateEntries, to get all entities regardless of state?

Answer 1

EntityState is a flags enums which means that you can combine multiple values when invoking GetObjectStateEntries like this:

ObjectStateManager.GetObjectStateEntries(EntityState.Unchanged | EntityState.Deleted)

On the other hand since the deleted entities are already marked as deleted they will be sent to the database anyways for deletion so I am not sure what you are going to do with them.
