MapperToolkit 1.0.1.9-alpha

MapperToolkit

This project is a Mapper library use Source Generator with function such as:

• mapper: object-object mapper .
• transoform:by object (entity) build specified model (DTO) .

MapperToolkit is the fastest .NET object mapper if member inclube List IEnumerable surpassing even the manual mapping and Mapperly The benchmark was generated with(https://github.com/GaoNian-NET/Benchmark.netCoreMappers).

Quickstart

Installation

Add the NuGet Package to your project:

dotnet add package MapperToolkit

Create your first mapper

//example Entity
public class Entity
{
    public string Account { get; set; }
    public DateTime CreateTime { get; set; }
}

//example DTO
public class DTO
{
    public string EmpNo { get; set; }
    public string EmpName { get; set; }
    public DateTime CreateTime { get; set; }
}

Create profile class inherit MapperToolkit.Profile in constructors type mapper code

// Profile declaration
public class MappingProfile : Profile
{
    public MappingProfile()
    {
        GenerateAllMapper<Entity, DTO>()
        .Map(src => src.Account[0..4],dest=>dest.EmpNo)
        .Map(src => src.Account[4..^0],dest=>dest.EmpName);
    }
}

//Generator code
 public static partial class DTOMapper
{
    public static global::ConsoleApp.DTO MapperToDTO(this global::ConsoleApp.Entity source)
    {
        global::ConsoleApp4.DTO result = new();
        global::System.Func<global::ConsoleApp.Entity, string> EmpNoMapper = src => src.Account[0..4];
        global::System.Func<global::ConsoleApp.Entity, string> EmpNameMapper = src => src.Account[4..^0];
        result.EmpNo = EmpNoMapper.Invoke(source);
        result.EmpName = EmpNameMapper.Invoke(source);
        result.CreateTime = source.CreateTime;
        return result;
    }
}

//Mapper usage
var entity = new Entity() { Account = "A123Bojack" ,CreateTime = DateTime.Now };
var dto = entity.MapperToDTO();
Console.WriteLine($"EmpNo:{dto.EmpNo};EmpName:{dto.EmpName};CreateTime:{dto.CreateTime}");
// print EmpNo:A123;EmpName:Bojack;CreateTime:2022/8/16 12:13:15
