RSCG – AutoDeconstruct

Automatically add deconstruct for all types in an assembly

This is how you can use AutoDeconstruct .

The code that you start with is

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="AutoDeconstruct" Version="1.0.0" />
  </ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

// See https://aka.ms/new-console-template for more information
Console.WriteLine("Hello,World!");
var p = new Person();
p.FirstName = "Test";
p.LastName = "Ignat";
var (_,l,_ ) = p;
Console.WriteLine($"Last name is {l}");

// See https://aka.ms/new-console-template for more information
using AutoDeconstruct;

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

[NoAutoDeconstruct]
public class TestPerson
{
    public string? FirstName { get; set; }
    public string? LastName { get; set; }
    public string? Title { get; set; }

}

The code that is generated is

#nullable enable

public static partial class PersonExtensions
{
	public static void Deconstruct(this global::Person @self,out string? @firstName,out string? @lastName,out string? @title)
	{
		global::System.ArgumentNullException.ThrowIfNull(@self);
		(@firstName,@lastName,@title) =
			(@self.FirstName,@self.LastName,@self.Title);
	}
}
