Photosphere.Mapping

Simple high performance flat object mapper based on emitting CIL code.
It perform mapping by properties names and assignable types.

Status

Install via NuGet

PM> Install-Package Photosphere.Mapping

Interface

This tiny library gives next extension methods

void MapTo<TSource, TTarget>(this TTarget target, TSource source);    // Map from existent object to another one
void MapToObject(this object target, object source);                  // Map from existent object to another one
TTarget Map<TSource, TTarget>(this TSource source);                   // Map from existent object to new object
TTarget MapObject<TTarget>(this object source);                       // Map from existent object to new object

Examples

Map object source to existent object target

source.MapTo(target);

Map object source of type Foo to new object target of type Bar

var target = source.Map<Foo, Bar>();

You can perform mapping from anonymous type

var source = new { A = "a", B = 1 };
source.MapToObject(target);

or

var source = new { A = "a", B = 1 };
var target = source.MapObject<Bar>();

but not vice versa (to anonymous type object), because anonymous type objects are immutable by design.

Perfomance

You can see perfomance test and pefromance test result.
