Here is an example of what a Value Object looks like. No inheritance, so this can also be used for structs.

The Equals method simply delegates to the ValueObjectComparer. Same for the IEquatable interface implementation. The IEquatable interface uses a strongly typed Equals method, which is better for structs, as it will avoid boxing.

The difference between the built-in object's Equals and IEquatable is that the compiler will pick the most specific matching Equals(T other).

public class SomeObject : IEquatable<SomeObject>
{
  public string Name { get; set; }
  public int Age { get; set; }

  public override bool Equals(object obj)
    => ValueObjectComparer<SomeObject>.Instance.Equals(this, obj);

  public bool Equals([AllowNull] SomeObject other) 
    => ValueObjectComparer<SomeObject>.Instance.Equals(this, other);
}

Ignoring Certain Properties

Some Value Objects have calculated properties, and using them in the comparison is not necessary. You might want to use the ValueObjectComparer for other, non-value-object, types. So you might want to ignore certain properties for short.

Simply add the [Ignore] attribute to the property, and it won't be used for equality.

[Ignore]
public int NotUsed { get; set; }
