Inspecting EntityValidationErrors

try { context.[table name].Add([object]) // Could also be before try if you know the exception occurs in SaveChanges context.SaveChanges(); } catch (DbEntityValidationException e) { foreach (var eve in e.EntityValidationErrors) { Console.WriteLine("Entity of type \"{0}\" in state \"{1}\" has the following validation errors:", eve.Entry.Entity.GetType().Name, eve.Entry.State); foreach (var ve in eve.ValidationErrors) { Console.WriteLine("- Property: \"{0}\", Error: \"{1}\"", ve.PropertyName, ve.ErrorMessage); } } throw; }
