ChangeTracker.HasChanges Method


Checks if any new, deleted, or changed entities are being tracked such that these changes will be sent to the database if SaveChanges() or SaveChangesAsync(CancellationToken) is called.

public virtual bool HasChanges ();
abstract member HasChanges : unit -> bool
override this.HasChanges : unit -> bool
Public Overridable Function HasChanges () As Boolean


true if there are changes to save, otherwise false.


This method calls DetectChanges() to ensure the returned value is accurate. Since detecting changes can be slow, consider temporarily setting AutoDetectChangesEnabled to prevent detecting changes in situations where the state is known to be up-to-date.

See EF Core change tracking for more information and examples.
