Override Equals and GetHashCode

• Override Equals and GetHashCode

Quando for sobrescrever um dos dois, deve se sobrescrever o outro também

public class ImaginaryNumber : IEquatable<ImaginaryNumber>
{
    public double RealNumber { get; set; }
    public double ImaginaryUnit { get; set; }

    public override bool Equals(object obj)
    {
        return Equals(obj as ImaginaryNumber);
    }

    public bool Equals(ImaginaryNumber other)
    {
//MESMAS PROPRIEDADES USADAS AQUI DEVEM SER USADAS NO GETHASHCHODE
        return other != null &&
               RealNumber == other.RealNumber &&
               ImaginaryUnit == other.ImaginaryUnit;
    }

    public override int GetHashCode()
    {
        return HashCode.Combine(RealNumber, ImaginaryUnit);
    }
}
