How to configure AbpAutoMapperOptions to expression mapping?

Viewed 47

I want to configure an abp.io application project to successfully map Expression<Func<TDto, bool>> to Expression<Func<TEntity, bool>> I don't know is that can be done by Volo.Abp.ObjectMapping I succussed to get mapping work like that

var mapper = new Mapper(new MapperConfiguration(cfg =>
        {
            cfg.AddExpressionMapping();
            cfg.CreateMap<Category, CategoryDto>();
        })
);

var predicateConverted =mapper.MapExpression <Expression<Func<Category, bool>>>(predicate);

but I think I should but that configuration with

public override void ConfigureServices(ServiceConfigurationContext context)
    {
        Configure<AbpAutoMapperOptions>(options =>
        {
            options.AddMaps<TesttApplicationModule>();
        });
    }

You need to use the AutoMapper.Extensions.ExpressionMapping package for expression mapping and use the AddExpressionMapping method (as you mentioned).


You can configure the AbpAutoMapperOptions option as follow to enable expression mapping (after adding the related package to your *.Application project):

Configure<AbpAutoMapperOptions>(options =>
{
   //add a new configurators and call the AddExpressionMapping()
   options.Configurators.Add(config =>
   {
       config.MapperConfiguration.AddExpressionMapping();
   });
            
   options.AddMaps<TesttApplicationModule>();
});
