AutoGenerate Mapping

This is how you can use MapTo .

The code that you start with is

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net7.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

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

	<ItemGroup>
	  <PackageReference Include="MapTo" Version="0.9.1" />
	</ItemGroup>

</Project>

The code that you will use is

// See https://aka.ms/new-console-template for more information
using mapperlyDemo;
var p=new Person();
p.FirstName = "Andrei";
p.LastName = "Ignat";
PersonDTO dto = p.MapToPersonDTO();
Console.WriteLine(dto.FullName);

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

using MapTo;

namespace mapperlyDemo;
[MapFrom(typeof(Person))]
public class PersonDTO
{
    public int ID { get; set; }
    public string? FirstName { get; set; }
    public string? LastName { get; set; }

    [IgnoreProperty]
    public string FullName { 
        get
        {
            return FirstName + " " + LastName;
        }
    }
}

The code that is generated is

// <auto-generated />
#nullable enable

namespace mapperlyDemo;

[global::System.CodeDom.Compiler.GeneratedCodeAttribute("MapTo","0.9.1.51471")]
public static class PersonMapToExtensions
{
    [return: global::System.Diagnostics.CodeAnalysis.NotNullIfNotNull("person")]
    public static global::mapperlyDemo.PersonDTO? MapToPersonDTO(this Person? person)
    {
        if (ReferenceEquals(person,null))
        {
            return null;
        }

        return new PersonDTO
        {
            ID = person.ID,
            FirstName = person.FirstName,
            LastName = person.LastName
        };
    }
}
