ExprMapper 1.0.0

ExprMapper

Simple C# POCO classes mapper, based on the Expressions generation.

How it works?

Based on the class structure, it generates binding expression, which is compiled into the function. It tracks class properties and generates the following code:

return new Destination {
	PropInt = source.PropInt,
	PropStr = source.PropStr,
	PropRef = source.PropRef != null ? PropRef : null,
	// ...
}

Features

• Objects mapping with null references handling
• Nested objects mapping
• Mapping collection types (array, list & IEnumerable), as well as the collection type properties
• Custom mapping functions for selected properties

How to use it?

First, create the mapper instance, which defines available mappings:

var mapper = new Mapper()
    .Add<L, R>()
    .Add<UserDTO, User>();

Then just call:

var result = mapper.Map<L, R>(someObj);  // L -> R

Defining the mapping with custom bindings:

var mapper = new Mapper().Add<L, R>(
	(r => r.Id, l => l.Id.ToString())
	(r => r.Year, l => (short)l.Date.Year)
);
