MB.FastAutoMapper
The aim of this project is to provide compile-time support for auto-mapping by using source generation. The ubiquitous AutoMapper instead builds the mapping code at run-time.
One of the benefits of this approach, besides paying the mapping cost at compile-time instead of run-time everytime, is that any mapping errors are also caught at compile time due to the strict type-safety of C#.
The code is pretty simple to use, simply reference the NuGet package MB.FastAutoMapper
and write something like this:
using FastAutoMapper;
class Src
{
public string Text { get; set; }
public float[] Color { get; set; }
}
class Dst
{
public string Text { get; set; }
public Vector3 Color { get; set; }
}
// first declare the mapper class, make sure it is a partial type
partial class Mapper : FastAutoMapperBase { }
// then declare your instance
var mapper = new Mapper();
// define the maps you need, including any conversions with `ForMember`
mapper.CreateMap<From, To>()
.ForMember(x => x.Color, x => new Vector3(x.Color[0], x.Color[1], x.Color[2]));
// and map your instances
var dst = mapper.Map(new Src { Text = "meep", Color = new[] { .1f, .5f, 1f } });
