DeepMapper 1.0.6

Deep Mapper

It is an object mapper with zero configuration. It maps using two methods conventional mapping and configurational mapping. It also maps nested classes recursivley to a new instance. This library can be used for deep copying as well.

Add DI to the project.

services.AddDeepMapping(config => 
{ 
     config.UseConventionalMapping();
});

Conventional Mapping

This method requires no configurations and uses property names to map objects and set the unmatched properties to default. Use IConventionalMapper interface or IDeepMapper. This class can be used without DI just by instantiating a new instance of ConventionalMapper class.

var obj = mapper.Map<TDestination>(TSource);

//or 

var obj = new ConventionalMapper().Map<TDestination>(TSource);

//or 

var destintion = new ConventionalMapper().Map(Type destinationType, object? sourceObject)

Conventioal mapping can use constructors to fill destination class.

class TDestination 
{
  public TProperty Property {get; private set;}
}

// Or

class TDestination 
{
  TDestination(TProperty property)
  {
     Property = property
  }
  public TProperty Property {get;}
}
 

Conventional mapper is able to map structs to classes (and vice versa) to fill properties with the same name. The convention is case insensitive.

Configurational Mapping

In this method the library uses configuration for a types in the service registeration.

config.Map<TSource, TDestination>()
              .ToProperty(destination => TProperty, source => TProperty)
              .ToConstant(destination => TProperty, object)
              .ToDefault(destination => TProperty)
              .Ignore(destination => TProperty);

The UseConventionalMapping() in the configuration enables the configurational mapper to map the rest of the properties using name conventions.

// Use IDeepMapper for configurational mapping
var obj = mapper.Map<TDestination>(TSource);

Version 1.0.3

• MapAsync has been added to IDeepMapper for async mapping.
• Map functions has been added to IEnumerable interface for mapping collection in DeepMapper.Extensions namespace. This must be used when DI activated.
• The DI extension moved to new namespcace DeepMapper.Extensions alongside Map for IEnumerable.

// Map for IEnumerable
IEnumerable<TDestination> objects = IEnumerable.Map<TDestination>();

Version 1.0.5

• MapDictionary has been added to Conventional mapper.

var keyValue = new Dictionary<string, object?>();
keyValue["P1"] = "ONE";
keyValue["P2"] = "TWO";
keyValue["P3"] = new object();

var newObj = new ConventionalMapper().Map<T>(keyValue);

Version 1.0.6
