This will generate code for investigating at runtime the properties of an object
The code that you start with is
//no special requirements
class Person
{
[Required]
public string FirstName { get; set; }
public string LastName { get; set; }
}
The code that you will use is
var pOldPerson = new Person();
pOldPerson.FirstName = "Andrei";
var prop = pOldPerson.GetProperties().Values ;
foreach (var item in prop)
{
Console.WriteLine($"{item.Name} Attr: {item.Attributes.Length} value {item.Name}");
if(item.TryGetValue(pOldPerson, out var val)){
Console.WriteLine("value : " + val);
}
}
The code that is generated is
using System;
using System.Linq;
namespace Apparatus.AOT.Reflection
{
public static class CopyConstructor_PersonExtensions
{
[global::System.Runtime.CompilerServices.ModuleInitializer]
public static void Bootstrap()
{
MetadataStore<global::CopyConstructor.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::CopyConstructor.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::CopyConstructor.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::CopyConstructor.Person value)
{
return _lazy.Value;
}
}
}
