## Usage

### One-way Mapping Profile

``` csharp

record BarEntity(Guid Id, string Value);

record BarDto(Guid Id, string Value);

class BarMappingProfile : OneWayProfile

{

}

```

### Two-way Mapping Profile

``` csharp

record FooEntity(Guid Id, string Value);

record FooDto(Guid Id, string Value);

class FooMappingProfile : TwoWayProfile

{

}

```

### Two-way Mapping Profile (Explicit)

``` csharp

class TransactionEntity

{

    public int Id { get; set; }

    public Guid OperatorId { get; set; }

    public DateTimeOffset ProcessedAt { get; set; }

    public double Amount { get; set; }

}

class TransactionDto

{

    public int Id { get; set; }

    public long ProcessedAt { get; set; }

    public double Amount { get; set; }

}

class TransactionMappingProfile : TwoWayProfile

{

    public override void ConfigureLeftToRightMapping()

    {

        CreateMap()

            .ForMember(

                dto => dto.Id,

                options => options.MapFrom(entity => entity.Id))

            .ForMember(

                dto => dto.ProcessedAt,

                options => options.MapFrom(entity => entity.ProcessedAt.ToUnixTimeMilliseconds()))

            .ForMember(

                dto => dto.Amount,

                options => options.MapFrom(entity => entity.Amount));

    }

    public override void ConfigureRightToLeftMapping()

    {

        CreateMap()

            .ForMember(

                entity => entity.Id,

                options => options.MapFrom(dto => dto.Id))

            .ForMember(

                entity => entity.OperatorId,

                options => options.Ignore())

            .ForMember(

                entity => entity.ProcessedAt,

                options => options.MapFrom(dto => DateTimeOffset.FromUnixTimeMilliseconds(dto.ProcessedAt)))

            .ForMember(

                entity => entity.Amount,

                options => options.MapFrom(dto => dto.Amount));

    }

}

```
