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 } });
