This will generate code for investigating at runtime the properties of an object

 

This is how you can use ApparatusAOT .

The code that you start with is

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

	<PropertyGroup>
		<OutputType>Exe</OutputType>
		<TargetFramework>net7.0</TargetFramework>
	</PropertyGroup>

	<ItemGroup>
		<PackageReference Include="Apparatus.AOT.Reflection" Version="0.2.0" />
	</ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>

</Project>

The code that you will use is

using Apparatus.AOT.Reflection;
using ApparatusDemo;
using System;

Person p1 = new();
p1.FirstName = "Andrei1";
p1.LastName = "Ignat1";

Person p2 = new ();
p2.FirstName = "Andrei2";
p2.LastName = "Ignat2";

var prop =p1.GetProperties().Values;
foreach (var item in prop)
{
    Console.WriteLine($"{item.Name} Attr: {item.Attributes.Length} value {item.Name}");
    if (item.TryGetValue(p1, out var val))
    {
        Console.WriteLine("value : " + val);
    }

}
foreach (var item in prop)
{
    Console.WriteLine($"{item.Name} Attr: {item.Attributes.Length} value {item.Name}");
    if (item.TryGetValue(p2, out var val))
    {
        Console.WriteLine("value : " + val);
    }

}

using System.ComponentModel.DataAnnotations;
namespace ApparatusDemo;
class Person
{
    [Required]
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

 

The code that is generated is

using System;
using System.Linq;

namespace Apparatus.AOT.Reflection
{
    public static class ApparatusDemo_PersonExtensions
    {
        [global::System.Runtime.CompilerServices.ModuleInitializer]
        public static void Bootstrap()
        {
            MetadataStore<global::ApparatusDemo.Person>.Data = _lazy;
        }

        private static global::System.Lazy<global::System.Collections.Generic.IReadOnlyDictionary<string, IPropertyInfo>> _lazy = new global::System.Lazy<global::System.Collections.Generic.IReadOnlyDictionary<string, IPropertyInfo>>(new global::System.Collections.Generic.Dictionary<string, IPropertyInfo>
        {
            { "FirstName", new global::Apparatus.AOT.Reflection.PropertyInfo<global::ApparatusDemo.Person,string>(
                        "FirstName", 
                        new global::System.Attribute[] 
                        {
                            new global::System.ComponentModel.DataAnnotations.RequiredAttribute(),
                        }, 
                        instance => instance.FirstName, (instance, value) => instance.FirstName = value)
                },
            { "LastName", new global::Apparatus.AOT.Reflection.PropertyInfo<global::ApparatusDemo.Person,string>(
                        "LastName", 
                        new global::System.Attribute[] 
                        {
                            
                        }, 
                        instance => instance.LastName, (instance, value) => instance.LastName = value)
                },
        }); 


        internal static global::System.Collections.Generic.IReadOnlyDictionary<string, IPropertyInfo> GetProperties(this global::ApparatusDemo.Person value)
        {
            return _lazy.Value;
        }   
    }
}
