Is there a way to call a method after ProjectToType<T> is completed?

[bhagavan44]

I wanted to modify a property value after the result is retrieved from the database with ProjectToType . AfterMappingInline and AfterMapping is not executed when we use the ProjectToType. What are the other options in this situation?

This is something I'm interested in. Have you found a solution, @bhagavan44 ?

@savornicesei I was unable to find a suitable solution for that issue, so I decided to create my own code mapping tailored specifically to my use case.

@bhagavan44 Thank you.

It is possible to use translations at mapping level but I doubt they'll work with ProjectToType

using Mapster;
using Microsoft.Extensions.Localization;
public class MappingConfig
{
    public static void ConfigureMappings(IStringLocalizer localizer)
    {
        TypeAdapterConfig<Entity, TranslatedDto>
            .NewConfig()
            .Map(dest => dest.TranslatedDescription, 
                 src => localizer[src.Description]); // Translate the Description field
    }

It is also possible to intercept materialized objects in EF Core and EF6 and apply translations there but that works only for table-entitites, not for composite ones.

As far as I understand, ProjectToType is needed to optimize the request, when the number of members in the destination type is less than in the source.
There is no point in using it to modify already received data.

It should work if localizer is a function localizer(src.Description)

TypeAdapterConfig<Entity, TranslatedDto>
           .NewConfig()
           .Map(dest => dest.TranslatedDescription, 
                src => localizer[src.Description]); // Translate the Description field
