Generating XML serializer without reflection

This is how you can use StackXML .

The code that you start with is

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net9.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>
	<ItemGroup>
		<PackageReference Include="StackXML" Version="1.0.0" OutputItemType="Analyzer"  />
	</ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

using SerializerDemo;
using StackXML;

var p= new Person() { Name= "Andrei Ignat" , Age=55};
var str= XmlWriteBuffer.SerializeStatic(p);
Console.WriteLine(str);
var entity = XmlReadBuffer.ReadStatic<Person>(str);
Console.WriteLine("name is "+entity.Name);

using StackXML;

namespace SerializerDemo;
[XmlCls("person")]
public partial class Person
{
    [XmlField("age")]
    public int Age;
    [XmlField("name")]
    public string Name = string.Empty;

    
}

The code that is generated is

using System;
using System.IO;
using System.Collections.Generic;
using StackXML;
using StackXML.Str;

// <auto-generated/>
#pragma warning disable

namespace SerializerDemo
{
    /// <inheritdoc cref="Person"/>
    partial class Person : IXmlSerializable
    {
        public virtual ReadOnlySpan<char> GetNodeName()
        {
            return "person";
        }

        public virtual bool ParseAttribute(ref XmlReadBuffer buffer, ReadOnlySpan<char> name, ReadOnlySpan<char> value)
        {
            switch (name)
            {
                case "age": {
                    this.Age = buffer.m_params.m_stringParser.Parse<System.Int32>(value);
                    return true;
                }
                case "name": {
                    this.Name = value.ToString();
                    return true;
                }
            }
            return false;
        }

        public virtual void SerializeAttributes(ref XmlWriteBuffer buffer)
        {
            buffer.PutAttribute("age", Age);
            buffer.PutAttribute("name", Name);
        }

        public virtual bool ParseFullBody(ref XmlReadBuffer buffer, ReadOnlySpan<char> bodySpan, ref int end)
        {
            return false;
        }
        public virtual bool ParseSubBody(ref XmlReadBuffer buffer, ReadOnlySpan<char> name, ReadOnlySpan<char> bodySpan, ReadOnlySpan<char> innerBodySpan, ref int end, ref int endInner)
        {
            return false;
        }

        public virtual void SerializeBody(ref XmlWriteBuffer buffer)
        {
        }
    }
}
