AutoMapper Enum to byte with implemention IMapperConfigurator

Question

Enum definition is

public enum RowStatusEnum
{
    Modified = 1,
    Removed = 2,
    Added = 3
}

public class RowStatusEnumConvertor : IMapperConfigurator
{
           


        

Answer 1

Starting from version 9 of Automapper there were changes in initialization which caused to be out of date above examples. I updated above example and left original values to have also reference to older version (NUnit 3.12.0):

RowStatusEnum

namespace StackOverflow.RowStatus
{
    public enum RowStatusEnum
    {
        Modified = 1,
        Removed = 2,
        Added = 3
    }
}

AutoMapperConfigurator.cs

namespace StackOverflow.RowStatus
{
    using System;
    using System.Linq;

    using AutoMapper;

    public class MyProfile : Profile
    {
        public MyProfile()
        {
            CreateMap().ConvertUsing(
                x => Enum.GetValues(typeof(RowStatusEnum))
                    .Cast().First(y => (byte)y == x));
            CreateMap().ConvertUsing(
                x => (byte)x);
        }
    }
}

MappingTests

namespace StackOverflow.RowStatus
{
    using AutoMapper;

    using NUnit.Framework;

    [TestFixture]
    public class MappingTests
    {
        [Test]
        public void AutoMapper_Configuration_IsValid()
        {
            var config = new MapperConfiguration(cfg => cfg.AddProfile());
            config.AssertConfigurationIsValid();
        }

        [TestCase(1, ExpectedResult = RowStatusEnum.Modified)]
        [TestCase(2, ExpectedResult = RowStatusEnum.Removed)]
        [TestCase(3, ExpectedResult = RowStatusEnum.Added)]
        public RowStatusEnum AutoMapper_ConvertFromByte_IsValid(
            byte rowStatusEnum)
        {
            var config = new MapperConfiguration(cfg => cfg.AddProfile());
            var mapper = config.CreateMapper();
            return mapper.Map(rowStatusEnum);
        }

        [TestCase(RowStatusEnum.Modified, ExpectedResult = 1)]
        [TestCase(RowStatusEnum.Removed, ExpectedResult = 2)]
        [TestCase(RowStatusEnum.Added, ExpectedResult = 3)]
        public byte AutoMapper_ConvertFromEnum_IsValid(
            RowStatusEnum rowStatusEnum)
        {
            var config = new MapperConfiguration(cfg => cfg.AddProfile());
            var mapper = config.CreateMapper();
            return mapper.Map(rowStatusEnum);
        }
    }
}
