Generating function to map DTOs

This is how you can use AutoGen .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>

	<ItemGroup>
	  <PackageReference Include="Antelcat.AutoGen" Version="1.0.0-pre-alpha-7" />
	</ItemGroup>

	
</Project>

The code that you will use is

using mapperDemo;
var p=new Person();
p.FirstName = "Andrei";
p.LastName = "Ignat";
PersonDTO dto= p.ToDTO();
Console.WriteLine(dto.FullName);

public class Person
{
    public int ID { get; set; }
    public string? FirstName { get; set; }
    public string? LastName { get; set; }
}

using Antelcat.AutoGen.ComponentModel.Mapping;

namespace mapperDemo;
public class PersonDTO
{
    public int ID { get; set; }
    public string? FirstName { get; set; }
    public string? LastName { get; set; }
    [MapIgnore]
    public string FullName { 
        get
        {
            return FirstName + " " + LastName;
        }
    }
}

using Antelcat.AutoGen.ComponentModel.Mapping;

namespace mapperDemo;

public static partial class Extensions
{
    [AutoMap(Extra = [nameof(AfterMap)])]
    public static partial PersonDTO ToDTO(this Person person);

    private static void AfterMap(Person person,PersonDTO personDTO)
    {
        person.ID= personDTO.ID;
    }
}

The code that is generated is

// <auto-generated/> By Antelcat.AutoGen
#pragma warning disable
#nullable enable
namespace mapperDemo
{
    partial class Extensions
    {
        [global::System.CodeDom.Compiler.GeneratedCodeAttribute("Antelcat.AutoGen.SourceGenerators.Generators.Mapping.MapperGenerator","1.0.0.0")]
        [global::System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverageAttribute]
        public static partial global::mapperDemo.PersonDTO ToDTO(this global::Person person)
        {
            var ret = new global::mapperDemo.PersonDTO()
            {
                ID = person.ID,
                FirstName = person.FirstName,
                LastName = person.LastName,
            };
            global::mapperDemo.Extensions.AfterMap(person,ret);
            return ret;
        }
    }
}
