How do I get started

First configure DeepDiff to know what types you want to compare, in the startup of your application

var diffConfiguration = new DiffConfiguration(); diffConfiguration.Entity<Entity>() .HasKey(x => new { x.StartsOn, x.Name }) .HasValues(x => new { x.Price, x.Volume }) .HasMany(x => x.SubEntities) .MarkAsInserted(x => x.PersistChange, PersistChange.Insert) .MarkAsUpdated(x => x.PersistChange, PersistChange.Update) .MarkAsDeleted(x => x.PersistChange, PersistChange.Delete);; diffConfiguration.PersistEntity<SubEntity>() .HasKey(x => x.SubName) .HasValues(x => x.Energy) .MarkAsInserted(x => x.PersistChange, PersistChange.Insert) .MarkAsUpdated(x => x.PersistChange, PersistChange.Update) .MarkAsDeleted(x => x.PersistChange, PersistChange.Delete);; var deepDiff = diffConfiguration.CreateDeepDiff();

Then in your application code

var results = deepDiff.DiffMany(existingEntities, newEntities).ToArray();

Sample entities definition

public class Entity { public Guid Id { get; set; } // DB Key public DateTime StartsOn { get; set; } // Business Key public string Name { get; set; } // Business Key public int Price { get; set; } public int Volume { get; set; } public PersistChange PersistChange { get; set; } public List<SubEntity> SubEntities { get; set; } } public class SubEntity { public Guid Id { get; set; } // DB Key public string SubName { get; set; } // Business Key public int Energy { get; set; } public PersistChange PersistChange { get; set; } } public enum PersistChange { None, Inserted, Updated, Deleted }
