AutoMapper/AutoMapper
AutoMapper
AutoMapper is a .NET object-to-object mapper designed to transfer data between different object types. It functions as an automated mapping library that reduces the need for manual property assignments by using naming conventions to match properties between classes.
The library focuses on automating data projection and the conversion of internal domain models into data transfer objects. It supports layered architecture decoupling by mapping data between domain entities and view models.
The system employs convention-based member matching, flattening-based property projection, and recursive type resolution. It utilizes expression-tree compilation and a configuration-based mapping cache to handle object transformations, while providing a type-converter pipeline for incompatible data formats.
Features
- .NET Object Mapping - Acts as a specialized .NET library for transferring data between different object types using conventions.
- Automated Data Projection - Projects database query results directly into specific object shapes without manual field-by-field mapping.
- Object Mapping Libraries - Simplifies the conversion of data transfer objects to domain models and vice versa.
- Object-to-Object Mappers - Provides a library for transferring data between different object types in .NET using convention-based mapping.
- Data Transfer Object Mapping - Provides automated mapping between domain entities and data transfer objects to decouple APIs from internal schemas.
- Convention-Based Data Mapping - Automatically matches properties of different classes based on naming standards to reduce manual assignment code.
- Convention-Based Matching - Automatically matches source and destination properties by comparing names and types using predefined naming rules.
- Type-Converter Pipelines - Routes the mapping process through a chain of custom converters to transform incompatible data types.
- Object Flattening - Converts complex nested source objects into a single-level structure by concatenating property names.
- Expression Tree Compilation - Compiles mapping definitions into executable delegates using expression trees to eliminate repeated reflection during transformation.
- Recursive Type Resolution - Walks through nested object hierarchies to resolve and instantiate child types based on mapping configurations.
- Mapping Caches - Implements a configuration-based mapping cache to store compiled functions and ensure high-performance reuse.
- Layered Architectures - Separates application layers by mapping data between domain entities and view models.
- Core .NET Libraries - Convention-based library for mapping between object models.
- General Utilities - Convention-based object-to-object mapping for .NET applications.
- Object Mapping - Convention-based object-to-object mapping for .NET applications.
