这个问题是因为在 AutoMapper 或 AutoMapper.Data 中，AddDataReaderMapping 方法现在需要提供一个 TypeMapConfiguration 对象。下面是一个示例：

using AutoMapper;
using AutoMapper.Configuration.Conventions;
using AutoMapper.Data;
using Dapper;
using System.Data.Common;

public class MyProfile : Profile
{
    public MyProfile()
    {
        var mapperConfiguration = new MapperConfigurationExpression();
        mapperConfiguration.AddDataReaderMapping();

        CreateMap()
            .ConvertUsing(r =>
            {
                var myType = new MyType();
                myType.Id = r.GetInt32(r.GetOrdinal("Id"));
                myType.Name = r.GetString(r.GetOrdinal("Name"));
                return myType;
            });

        CreateMap()
            .ConvertUsing(t => new[]
            {
                new SqlParameter("Id", t.Id),
                new SqlParameter("Name", t.Name),
            });

        CreateMap()
            .ForMember(x => x["Id"].Value, opt => opt.MapFrom(t => t.Id))
            .ForMember(x => x["Name"].Value, opt => opt.MapFrom(t => t.Name));

        Register(mapperConfiguration);
    }
}

public class MyType
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public static class Program
{
    public static void Main()
    {
        var configuration = new ConfigurationBuilder()
            .AddMaps(typeof(MyProfile).Assembly)
            .AddMapperDataTypes()
            .Build();

        using (var connection = new NpgsqlConnection("Connection String"))
        {
            connection.Open();

            var command = connection.CreateCommand();
            command.CommandText = "SELECT * FROM MyTable;";
            var reader = command.ExecuteReader();

            while (reader.Read())
            {
                var myType = Mapper.Map(reader);
                Console.WriteLine($"ID: {myType.Id}, Name: {myType.Name}");
            }
        }
    }
}
