RSCG – CommonCodeGenerator

Generating ToString from classes

This is how you can use CommonCodeGenerator .

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>
	<ItemGroup>
		<PackageReference Include="CommonCodeGenerator" Version="0.2.0" />
		<PackageReference Include="CommonCodeGenerator.SourceGenerator" Version="0.2.0">
			<PrivateAssets>all</PrivateAssets>
			<IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
		</PackageReference>
	</ItemGroup>

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

The code that you will use is

using ToStringData;

Console.WriteLine("Hello,World!");
Person person = new ();
person.FirstName = "Andrei";
person.LastName = "Ignat";
Console.WriteLine(person.ToString());

using CommonCodeGenerator;

namespace ToStringData;
[GenerateToString]
internal partial class Person
{
    public string? FirstName { get; set; }
    public string? LastName { get; set; }

    [IgnoreToString]
    public int Age { get; set; }
}

The code that is generated is

// <auto-generated />
#nullable disable
namespace ToStringData
{
    partial class Person
    {
        public override string ToString()
        {
            var handler = new global::System.Runtime.CompilerServices.DefaultInterpolatedStringHandler(0,0,default,stackalloc char[256]);
            handler.AppendLiteral("Person ");
            handler.AppendLiteral("{ ");
            handler.AppendLiteral("FirstName = ");
            handler.AppendFormatted(FirstName);
            handler.AppendLiteral(",");
            handler.AppendLiteral("LastName = ");
            handler.AppendFormatted(LastName);
            handler.AppendLiteral(" }");
            return handler.ToStringAndClear();
        }
    }
}
