AutoMapper的配置

1，安装AutoMapper 和 Autofac

命令：

Install-package AutoMapper

Install-package Autofac

using Autofac;
using AutoMapper;
using AutoMapper.Configuration;
using Morningstar.EquityFundamentals.Framework.Db.Chatbot;
using Morningstar.EquityFundamentals.Model.Chatbot;

namespace Morningstar.EquityFundamentals.Framework
{
    public static class ContainerBuilderExtension
    {
        public static ContainerBuilder LoadAutoMapper(this ContainerBuilder builder)
        {
            builder.RegisterType<MapperConfigurationExpression>().SingleInstance();
            builder.Register(m =>
            {
                var mapperConfigurationExpression = m.Resolve<MapperConfigurationExpression>();
                var instance = new MapperConfiguration(mapperConfigurationExpression);
                return instance;
            });
            builder.Register(m =>
            {
                var mapperConfiguration = m.Resolve<MapperConfiguration>();
                return mapperConfiguration.CreateMapper();
            });
            return builder;
        }
    }

    public class AutoMapperProfile : Profile
    {
        public void Mapping(ILifetimeScope scope)
        {
            var expression = scope.Resolve<MapperConfigurationExpression>();
            expression.CreateMap<AppInfo, AppInfoDto>();
        }
    }

    public static class AutoMapperHelper
    {
        public static TDestination Map<TDestination>(object source)
        {
            ContainerBuilder builder = new ContainerBuilder();
            builder.LoadAutoMapper();
            builder.RegisterType<AutoMapperProfile>();
            IContainer Container = builder.Build();

            using var scope = Container.BeginLifetimeScope();
            scope.Resolve<AutoMapperProfile>().Mapping(scope);
            return scope.Resolve<IMapper>().Map<TDestination>(source);
        }
    }
}
